Foresters and landowners in the forestry community are very aware of the impact of fires on our landscapes. Many of us use fire to provide conservation stewardship to forest ecosystems. As we now see with the ongoing historical wildfire events across the U.S., society needs to assess ways to live with fire, as opposed to continuing the long-term war on fire.
The debate now rages whether climate change is causing these catastrophic wildfires. Little consideration is given to the long-term, benign neglect of our public forests and its effects. People must begin to understand and accept that fire in the forest is as natural as rain or sunshine; it&rsquo;s how we need fires to behave in the forest that has become a concern.
Fire has helped forests evolve for thousands of years. Many people remain under the illusion that prior to European settlement, forests in North American were carpets of pristine, old-growth forests. Nothing could be further from the truth. Most forests were occupied and intentionally managed by Native Americans and fire was their primary tool.
I&rsquo;m not suggesting we can go back to the methods Native Americans utilized to sustain forested lands, but we can learn much from them. Mitigating the damages resulting from uncontrolled massive wildfire is going to take many years and complex solutions. We didn&rsquo;t get here over night, but by decades of poor land management decisions, policies and government regulation.
The past 40 years of hands-off preservationist policy discouraging active conservation stewardship on the land has led to forests overstocking themselves&mdash;an unnatural buildup of fire fuels in both quantity and structure, resulting in increased size and intensity of forest fires. Politicians have accepted the premise of &ldquo;Mother Nature knows best, thus, leave it alone.&rdquo; This thinking has resulted in disaster.
Additionally, we have permitted construction of homes, businesses, and infrastructure in fire-prone landscapes, only exasperating the overall fire problem.
As to climate change issues, our forests should be a major component of solving that problem. They should be carbon sinks that help naturally remove CO2 from our atmosphere. Instead, they are at risk to become a major source of carbon release.
Throughout the country, the forest is too overgrown to apply prescribed fire, so tree removal is required. In many areas, we simply cannot burn our way out of the crisis. We must integrate planned tree and timber harvesting. Of course, harvesting trees is the activity that has caused many special interests to block forest management by any means politically and socially. This has resulted in a dramatic decline in active forest management on most public lands over the past 50-plus years.
The good news is we have many excellent examples of integrated burning and thinning that has resulted in restored forest ecosystems that are aesthetically beautiful, more resilient to fire and insects, and more biologically diverse than the neglected lands nearby.&nbsp; One can visit the beautiful restoration of Ponderosa Pine systems in Arizona, Oregon and Washington, the beautiful conifer forests in the mountains of California, or the beautiful restoral long leaf pine forests of Florida and Georgia. It is unfortunate that the work done is only a drop in the bucket as to the scale of things that needs to be done in all regions.
The use of fire has its limitations, thus mechanical removal or treatment of trees remains an essential tool. Many areas are too close to homes or infrastructure and smoke becomes a real problem. Getting the right weather conditions on a given day to allow for the intentional setting of a fire is very limited and difficult. There are also ecological concerns at times. Allowing a fire to destroy a seed bank or burn into the turf can have devasting impacts to some ecosystems. The bottom line is that this is all complex. But we need to get on with what we know works.
The management of many of our forests requires an understanding of the fire ecology of those forests. It is not possible technically, physically or economically to apply management to all our conserved forest lands. Thus, nature will continue to be a partner in our forest management strategies. &nbsp;
None of this will be easy. Much of the restoration work requires the removal of small-diameter trees with no markets for this wood. Our new vision for forest and fire policy will need to consider the economic and tax policies that can make the needed work economically feasible. Utilizing wood fiber for renewable energy may be one of the key players in the needed forest restoration and management program. Biomass, small-diameter timber, pulpwood and wood chips all will play a role. Here in southern New Jersey, we have a fire culture on the land. Family forest landowners along with state fire wardens burn forests annually without concern or problem. It can be done&mdash;come see for yourselves. &nbsp; Author: Robert R.

Forests and Fires: Perfect Together, However…

Earlier this summer, Enviva was pleased to share a new piece of peer-reviewed research conducted by the team at Boundless Impact Investing, an independent research firm specializing in climate analytics for investors.
At the request of one of our largest unitholders, Boundless initially engaged with Enviva in the summer 2019 to begin to understand the carbon impact of wood pellet energy, as well as the sustainability of Enviva&rsquo;s supply chain. We found their work to be of such high quality that we asked them to conduct a deeper dive that could illustrate this more rigorous approach to carbon accounting, and to enable this research to be peer reviewed and shared widely. We are delighted to share their independent work.
As part of this research, Boundless used recent peer-reviewed literature on the greenhouse gas (GHG) impacts of wood pellets to create a life cycle analysis of GHG emissions from the wood pellet supply chain. They compared the performance of electricity generated using wood pellets versus other fuels such as coal and natural gas, examined Enviva&rsquo;s supply chain in the U.S. Southeast, and conducted an analysis of the U.K., German, and Japanese power sectors to understand the overall impact of bioenergy on meeting country-level GHG targets.
Boundless&rsquo;s entire piece is important, but the following are some highlights regarding three key facts from the report.
For steady-state working forests, you get the same net climate impact result no matter what assumptions are used for carbon accounting. The bottom line is this: crediting biogenic carbon uptake prior to combustion (i.e., the conventional approach applied in regulatory practice, where stack emissions are set to zero as long as the biomass is sourced from a region with stable or increasing carbon stocks) yields the same result for working forests as the carbon-debt accounting approach in which a debt is assigned at the time of combustion and is paid back as the forest regrows.
Renewable, baseload bioenergy enables the renewable electric grid. Solar and wind energy are important parts of the overall transition to a renewable energy grid, but these renewable sources are intermittent, meaning they don&rsquo;t produce power during times of the day or year when the wind doesn&rsquo;t blow or sun doesn&rsquo;t shine. Boundless found that we can balance the electricity grid with biomass to provide stability for other renewable sources of energy.&nbsp;&nbsp;&nbsp;
The carbon benefits of good biomass are clear. Boundless is careful to explain that its analysis is limited to the specific case of wood sourced sustainably as a by-product of a traditional timber harvest where the land returns to forested use, from a region with stable or increasing forest carbon stocks. In this we agree, of course&mdash;not all biomass is good biomass.
Biomass is essentially a natural storage vessel for energy from the sun. Trees from working forests are continuously recycling carbon from the atmosphere to trees and back. In contrast, fossil fuels represent a one-way trip for carbon from geologic storage to the atmosphere. As long as the requirements for good biomass are met, we can mitigate GHG emission by substituting bioenergy for fossil fuels.

The Environmental Impact of Wood Pellet Electricity 

It&rsquo;s what I like to call Windtober in Minnesota, that few-week period where the fall chill and lingering warm seem to battle each other, and much of what&rsquo;s in your yard&mdash;for me, my Styrofoam Halloween cemetery&mdash;blows away during those gusty days. The pretty colors fade to brown and the trees are stripped of their leaves seemingly overnight&mdash;winter is around the corner.
We&rsquo;re all grateful to be able to warm our homes or businesses at the push of a button. For some, that might involve tapping into a stockpile of wood pellets. Manufacturers have been readying for the season for many months, and despite the uncertainty the year has brought, things are looking good. As industry stakeholders often articulate, there are always unknowns, including heating degree days, market demand and other heating fuel prices. But this year has added another, and that&rsquo;s the downstream effects of fiber constraints caused by sawmills throttling down production during a pandemic that has no end in sight. Some have already felt the pinch, but for now, the data shows very modest implications. During times like these, finding ways to pinch pennies and save money is more important than ever. This is the theme of freelance writer Keith Loria&rsquo;s feature, &ldquo;Reducing Front-End Expenses,&rdquo; on page 10. Although this story focuses more on equipment and technology investments&mdash;mostly big picture&nbsp; strategies more so than short-term&mdash;there is some great advice in there from industry experts when it comes to fiber processing and handling logistics. During his discussion with Loria, Ken Upchurch, vice president of sales at marketing at Bruks Siwertell, touched on the difference choosing an automated versus manual woodyard can make on an operation&rsquo;s bottom line, which is applicable not just to wood pellet plants, but biomass power and thermal plants as well.&nbsp; &ldquo;Reducing the manpower and equipment used in a 500,000-ton-per-year plant can be significant,&rdquo; he says. &ldquo;Through automation, staffing can be reduced significantly. In addition, high-energy consumers such as dozers can be eliminated. The cost savings on an annual basis can easily exceed the $1 million threshold.&rdquo;
Related to this topic, you&rsquo;ll find a profile on KEITH Manufacturing&rsquo;s moving floor technologies, ideal for transporting anything from wood waste to municipal solid waste, and an excerpt from an interesting case study on the potential of straw-to-energy in a county in New York.
The last story I&rsquo;ll mention is &ldquo;RNG Revolution&rdquo; on page 16, in which I provided a snapshot of the North American RNG industry. In it, I speak with the RNG Coalition&rsquo;s Johannes Escudero on growth and drivers, challenges and more, and detail several examples of the versatile types of RNG-based projects recently built or under construction in the U.S. With landfill gas, wastewater treatment plants, animal manure, ag and food waste all being potential sources of RNG generation, it seems the potential is nearly endless. What will grease the industry tracks even more is continued and enhanced policy support.
This is final issue of Biomass Magazine in 2020, so I want to take the opportunity to thank you all for your continued readership and support. We're rooting for an &ldquo;unprecedented&rdquo; 2021, meaning the best year our respective industry sectors have had yet.

We're rooting for an â€œunprecedentedâ€� 2021, meaning the best year our respective industry sectors have had yet.

Closing Out the Year  with Optimism 

Whether transporting wood waste, ag residue or MSW, the ability to safely and efficiently deliver bulk material in almost any situation&mdash;high winds, uneven terrain, canopied storage areas&mdash;makes horizontal unloading a frequent necessity in biomass handling. This challenging work is made possible by the &ldquo;moving floor&rdquo; technologies developed by Oregon-based KEITH Manufacturing Co., maker of the world-renowned KEITH Walking Floor systems.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;
Offering its Walking Floor technology for both mobile and stationary applications, KEITH&rsquo;s customizable material handling solutions offer biomass handlers outstanding versatility. Walking Floor systems are comprised of a series of reciprocating slats&mdash;powered by a hydraulic drive&mdash;that serve as the floor of a trailer or bin. As the floor moves through its four-phase cycle, every third slat moves together. The friction of the load on the two sets of slats that remain in place keeps the load from moving while just one set of slats moves. During the final phase, all slats move in unison conveying the material. Safe, Reliable and Fast The Walking Floor system is as ingenious as it is simple. And it is not only reliable, but surprisingly fast. &ldquo;Our Walking Floor technology, with the right PTO, offers the fastest unloading speed of any moving system on the market,&rdquo; says KEITH Sales Director Mike Robinson. &ldquo;A mobile unit unloads a 45- to 48-foot trailer in 3 to 5 minutes. This is a big selling point for our systems because rapid turn times with biomass delivery is important to optimizing plant operations.&rdquo;&nbsp;&nbsp; &nbsp;
Further boosting the speed and convenience of the mobile Walking Floor unloader, KEITH offers an electric or hydraulic CleenSweep tarp system that, true to its name, cleans the floor of a Walking Floor trailer as it unloads material, essentially eliminating manual cleanup and reducing payload cross contamination. The automated system eliminates the need for brooms or manual tarps, making operator entry into the trailer unnecessary.
Robinson says Walking Floor systems are available in a variety of floor slat profiles and thicknesses, depending on the type of material being handled. There are slats designed for wood and agricultural residues, high-moisture loads, heavy duty and abrasive materials, bales, pallets, etc. The slats come standard in aluminum but are also available in stainless steel for very abrasive or corrosive materials. The standard 3.5-inch slats are principally flat with various profiles. For certain applications, v-shaped slats, pressure-seal slats or leak-proof slats are specified. &nbsp;
The self-unloading Walking Floor systems for trailers, which are sold through a nationwide network of dealers and trailer manufacturers, bring mobile unloading options to where tippers and dump trailers simply can&rsquo;t go: inside buildings and tunnels, under power lines, and on uneven or unstable ground.
Since the technology&rsquo;s inception more than 60 years ago, safety has been KEITH&rsquo;s top priority. The horizontal unloading action of the Walking Floor system is safer than dump or tipper trailers, which can overturn in windy conditions or because of load shift.
&ldquo;Walking Floor trailers keep your trailer on the ground,&rdquo; Robinson says. &ldquo;The biomass industry relies on our mobile systems because they are safe and reliable under almost all conditions, which minimizes operator risk and reduces unnecessary downtime caused by unforeseen conditions.&rdquo; Stationary Systems KEITH&rsquo;s Walking Floor conveyor for stationary storage and conveying bin systems are available in several configurations: pit-mounted, large storage bins, loader fed bins, as well as the company&rsquo;s patented DrivOn Bin system. Each configuration may be custom engineered to client specifications and can be designed with virtually unlimited dimensions and weight restrictions. These applications can be constructed to include multiple bins, walls, roofing and accessories.
&ldquo;KEITH is known for high-volume bins,&rdquo; says Kevin Desjardins of KEITH sales. &ldquo;Our systems can be designed to any weight or material conveying volume. Everything can be customized, from bin size&mdash;length, width, height&mdash;to the way it is configured.&rdquo;
Stationary Walking Floor bins can be engineered for up to 1,400 tons of storage capacity. And they come available with a variety of industrial material handling accessories such as infeed chutes, leveling screws, spike rolls and discharge augers. &ldquo;Our Walking Floor bins are custom-engineered from concept to construction,&rdquo; Desjardins says. &ldquo;We use site-specific engineering based on the client&rsquo;s needs: the type of facility, the throughput and type of material, and any other factor might help optimize the set up.&rdquo;
In fact, KEITH&rsquo;s moving floor solutions are often engineered into biomass facility designs to boost plant efficiency. Walking Floor bins eliminate manual labor costs and have relatively low power consumption. &ldquo;Our stationary application maximizes material throughput with the least amount of expended energy,&rdquo; Desjardins says. &ldquo;The system does not require increased power when you start it up, and all the mechanical components are outside the material zone for easy maintenance.&rdquo;
KEITH&rsquo;s specifications call for a minimum of 3 feet of clearance under a stationary bin&rsquo;s hydraulic drive for maintenance. This is achieved by pit-mounting the unit or installing an inverted drive. Each stand-alone hydraulic unit is designed for trouble free operation, and is mounted in a way that reduces contaminant entry.
KEITH Walking Floor bins provide what material handling experts call FIFO&mdash;"first in, first out&rdquo;&mdash;material rotation, offering consistent material flow that helps ensure product integrity. &ldquo;It&rsquo;s important to end users that the material they put into the unit first, comes out for processing first,&rdquo; says Desjardins. &ldquo;This is just one of many technical achievements we have mastered over several decades.&rdquo;

A bucket of biomass residue is dumped into a pit-mounted bin equipped with a KEITH Walking Floor system.

KEITH Walking Floor Systems: Moving Biomass Forward

Managers battled multiple issues in Q3 2020, including fires, hurricanes, COVID and market volatility. While lumber production surged, generating more residual volumes into fiber markets, demand from the pulp and paper sector continued to struggle with the impacts of the coronavirus on end-market products. The pandemic deteriorated market conditions for printing and writing paper while accelerating newsprint&rsquo;s decline. In the woods, the combustible mix of hot weather, strong winds and low humidity fueled explosive fires. Hurricane Laura added to the volatility, snapping 30 million tons of pine and 9 million tons of hardwood in Louisiana alone, comprising more wood than in-state mills consume in a typical year.
At the end of Q1 2020, uncertainty surrounding coronavirus impacts on lumber markets led to mill curtailments and a drawdown of inventory. Although housing slowed, it bounced back and became a bright spot for this year; housing starts for the three months ending in August were up 10% year-over-year. The uptick in housing, as well as repair and remodeling, increased lumber demand while supply chains were depleted, pushing lumber prices to record levels. According to the Producer Price Index (PPI), softwood lumber prices have risen 47% since April 2020, the highest four-month increase since data collection began in the 1940s (Figure 1). In August alone, prices rose 16% from the previous month, the highest monthly increase on record.
Responding to prices, lumber manufacturers increased production, generating more residual volumes into fiber markets as variance across end products in pulp and paper continued to separate winners from losers. Printing and writing papers remained unattractive, still &ldquo;eclipsed by newsprint for an uglier market,&rdquo; according to Forisk Wood Fiber Review Editor Tim Gammell. U.S. paper production in July and August was down over 13% year-over-year, while paperboard production declined 2.0%.
This imbalance put downward pressure on pulp fiber prices in the U.S. South Central&nbsp; region. Delivered softwood roundwood and residual chips both declined 2% in Q3 2020, representing a seven-year low for roundwood and a 10-year low for residual chips (Figure 2). Hardwood also declined with roundwood falling 3% and residual chips down 1%.
Following outages and mill upgrade projects, the eastern portion of the south central region was moving toward more supply/demand balance for pulp fiber. IP&rsquo;s Rome, Georgia, plant was operating again, and its mill in Selma, Alabama, was partially operating. Further west in the region, however, Hurricane Laura disrupted mill operations. In anticipation of the hurricane, mills in the projected pathâ€•WestRock Evadale and IP Orange amongst othersâ€•shut down. Though most mills returned to operations, the storm added volatility to the markets. Also, south central market dynamics included Domtar&rsquo;s announced plans to close the Kingsport, Tennessee, mill and convert it to recycled linerboard in three years. The company also announced the closure of its communication papers machine in Ashdown, Arkansas, and will convert it to fluff pulp production. Resolute FP strives to reopen the sawmill in El Dorado, Arkansas, later this year.
Although other sectors struggled, capital investments in U.S. export-oriented wood pellet capacity continued to increase, with most growth in the south central region. Pinnacle is constructing a 360,000-metric-ton (MT) facility in Demopolis, Alabama. The projectâ€•a joint venture between Pinnacle, Westervelt, and Two Rivers Lumberâ€•is scheduled to begin operations in Q2 2021. Enviva continues to advance on its announced &ldquo;Pascagoula Cluster.&rdquo; The company plans to build three 700,000 MT pellet plants in the Gulf Coast, one of which&mdash;Enviva Lucedale&mdash;is under construction and expected online by the end of 2021. Drax is expanding its Morehouse, Amite, and LaSalle facilities by a combined 350,000 MT, and Huntsville Pellets began operations at its 40,000-MT mill in Huntsville, Texas.
While the Forisk Wood Fiber Review tracks fiber prices over time and provides a snapshot from the first half of each quarter, it also captures imbalances across regions. U.S. south central pulp fiber prices declined in Q3 2020 as fiber supply outstripped demand. Sawmill manufacturing increased while pulp markets and production were spotty and relatively weaker. Capital continued to flow into the region&rsquo;s industrial wood pellet sector, however, with over 1.45 million MT of announced new capacity and resulting demand. Caution abounds with respect to lumber markets. Therefore, short-term planning horizons persists for many managers and executives.

U.S. South Central Fiber Prices: A Q3 Snapshot

The technology of straw/hay production and combustion is well developed and has been used for many years in Scandinavian countries, particularly in Denmark, where there are more than 8,000 small and large straw-fired heating plants collectively consuming more than 1.5 million tons of straw.
A study was conducted to investigate the opportunity to create a reliable and cost-effective source of straw and hay fuels for heat and power generation at a farm in Chautauqua County, New York. The following is an excerpt from a detailed report available upon request. &nbsp;
Chautauqua County Straw/Hay Production Capacity Chautauqua County farmers generate limited amounts of straw used for bedding and other needs. The straw is produced from growing mostly oats, as well as barley and wheat. These farmers have land and equipment necessary for production of low-quality hay for combustion in power and heat generation plants. It is estimated that the farmers can produce low-quality hay in the annual amount of 440,000 tons. This would supply fuel for power generating facilities with a capacity of 90 MW.
Farmers in the area are very interested in producing and supplying hay fuel at prices ranging from $4 to $5 per MMBtu. Most produce hay, with individual farm field crop production size ranging from 29 to 2,000 acres. Typically, two cuttings of hay are performed each year. Both round and square bales are produced by the farmers, with round being less costly to produce at 35 to 1,000 lbs. Square bales can range from 1,000 to 2,000 pounds.
Production capacity of hay is 3 to 4 tons per acre. Based on information provided by the farmers, the average farm gate cost of growing and harvesting hay is estimated at $52 per ton ($3.25 per MMBtu). Farmers, owning or renting the harvesting equipment, indicated that if profitable, they could produce all the hay needed. A majority is interested in using the ash from the combustion facility on their farms. Collection, Transportation and Storage Baling and transport. Baling capacity depends on the choice of technology. The baling capacity that includes all operations connected to baling is lowest when the straw/hay is baled by a small and round baler, and it is the highest when using a big baler.
When transporting straw/hay, various techniques and methods are used depending on the local conditions.
Small bales are loaded in the field by bale fork, bale loader, bale chute or bale gun. At the farm, bales are unloaded directly into the storage or an elevator or bale conveyor. Flat cars or special V-shaped vehicles are used. They will contain 75 to 250 bales.
Round bales are loaded by front-end loader, loader tractor or a trencher. The same machinery is used for unloading into storage. For transport, trucks or truck trailers are used, but also ordinary farm trailers or specially designed vehicles. Usually, the tractor is only towing one trailer, and it will contain from 8 to 14 bales.
Medium-sized bales are loaded and unloaded by front-end loader, trencher or a loader tractor. The front-end loader is the most used machine for both loading in the field and for unloading in the storage. The size of the loads varies 12 to 45 bales, but most often load will be 24 bales. Big bales are loaded and unloaded by front-end loader, trencher, loader tractor or a telescope loader, which is suitable for unloading because it can reach high up when storing in stacks. The front-end loader is the most widely used. Capacity is highest when handling two bales at a time. The size of the load varies from 6 to 18 bales. Over long distances, the tractor is often towing two trailers so that the size of the truckload attains 24 bales per trailer per trip. By handling big bales, the manpower required is about 13 minutes per ton.
Storage. In July and August, the straw/hay is harvested and collected. At the combustion facility, it is consumed evenly throughout the year, but due to the lack of storage facilities (typically only for three to five days), large power stations are not able to receive it until immediately before firing. Intermediate storage is typically provided at the farmers&rsquo; facilities. The supplier is paid for storing the bales at his own facility. Typically, payments for this service amount to 1% a month.
Delivery to plant. The straw/hay must be delivered to the plant in accordance with a crop delivery contract. It may be a direct agreement with the farmer, an association of crop producers, or a contractor. This agreement includes delivery dates, quantities to be supplied, contracted prices and quality criteria. Typically, a farmer transport, either a tractor or a truck, is used. The farmer loads and transports the crop to the plant, and the plant personnel unload it either by forklift truck or an overhead traveling crane. When transporting by haulage contractor, the farmer or the haulage contractor loads the track, and the haulage contractor travels to the plant. There, plant personnel unload the bales by forklift track. In transporting by tractor, the speed is considerably lower than by haulage contractor, and consequently, capacity is lower. The manpower requirement increases, and the capacity decreases with increased transport distance. The manpower required is greater and the capacity lower when transporting by tractor than by haulage contractor, and these differences increase with increasing transport distance.
When transporting by truck, there are almost always 12 bales loaded on the track and 12 bales on the track trailer distributed in two layers. This is also typical for tractor transport, but load sizes of 16 or 20 bales are typically used, particularly for transport over short distances. Plants unloading by crane require that the bales are arranged accurately on the vehicles, have a specified dimension and do not exceed a certain weight.
&nbsp;Crop price. Trading in crop for energy purposes among producers and the energy sector are determined by delivery contracts for several years, between the individual crop producer or an association of producers and the purchaser. The price is expressed in dollars per ton of delivered hay. The purchasers of fuel enter into long-term crop delivery contracts to ensure that they can supply heat and energy to the consumers. Not all fuel is traded according to crop delivery contracts, as plants may often obtain a better price for part of their annual consumption by spot market purchasing.
The producer's fuel price includes the return on investment and depreciation on the machinery, wages and cost of fuel in connection with growing, baling, and gathering, and costs of storage and transport to the generating plant. Additional costs include insurance and the producer&rsquo;s risk covering, i.e., due to shrinkage caused by bad weather conditions during the period of harvest and shrinkage during storage. Feasibility Analysis in Chautauqua County Four optimum site locations for the potential straw/hay-fired plants in Chautauqua County have been selected as: 3 MWe (megawatts electric) CHP facility located at the Airport Hill Industrial Park; two 2 MWt (megawatts thermal) district heating plants located at the BOCES New York Educational Centers&mdash;LoGuidice in Fredonia and Hewes in Ashville; and a 4 MWt district heating plant located at Jamestown Community College.
Each of the aforementioned sites has been investigated and analysis of electric and thermal loads performed. Based on this analysis, the optimum size of the hay-fired plant has been selected. The preliminary feasibility analysis for the 3 MWe Airport Hill CHP plant indicated that the power production cost is $65 per megawatt-hour. This cost is comparable with the energy cost produced by gas turbine installations at current gas prices.
The economic analysis of the straw/hay-fired district heating plants located at BOCES and JCC provide potential savings resulting in payback periods between 8 and 13 years, which are quite long. The implementation of these projects will require state and federal green power subsidies. Further escalation of fossil fuel prices will increase the economic feasibility of the hay-fired plants.
Potential benefits for Chautauqua County include 90 MW of potential straw/hay-fired capacity; 600 million kilowatt hours/year, generating $39 million annually; and creation of over 2,250 jobs. Conclusion It is recommended to proceed with the development of the proposed straw/hay-fired plants in Chautauqua County. To facilitate the implementation of the proposed projects, it is recommended to apply for cost-sharing grants to NYSERDA, the U.S. DOE and USDA.

Straw for Energy Generation in Chautauqua County

As unpresented wildfires ravage California&mdash;shattering records of total acres of land burned by more than double, and by early October, surpassing 4 million acres just this year&mdash;discussions of climate change mitigation efforts are becoming louder and more pressing than ever. Particularly for those feeling the heat when it comes reducing carbon footprints, interest in renewable natural gas (RNG) as an alternative vehicle fuel is an all-time high, and for good reason. Not only does it meet the most stringent emissions requirements, but for utilities and companies at which large vehicle fleets are essential for operating, making the switch is relatively easy and inexpensive. Announcements of transitions for large vehicle fleets are made almost daily&mdash;for example, in early September, the New York Metropolitan Transportation Authority inked a deal with Clean Energy Fuels Corp. to fuel the MTA&rsquo;s 800 transit buses with RNG. Less than a week later, CEFC announced that, in just a 45-day period, it had made new and extended deals for the supply of more than 20 million gallons of RNG for municipal and refuse vehicle fleets and fueling stations across the country.
Coincidentally, California happens to be the heart of North America&rsquo;s RNG boom, where conventional on-road natural gas is being rapidly displaced by RNG. In 2019, 77% of all on-road fuel used in natural gas vehicles in the state was RNG, according to the Coalition for Renewable Natural Gas, and its use as a transportation fuel has increased 210% in the past five years. The Low Carbon Fuel Standard has proven to be a powerful accelerator of RNG production and use, as RNG fuel use in natural gas vehicles across the rest of North America in 2019 was at 39%. A recent study by clean technology consulting firm Gladstein, Neandross &amp; Associates revealed that more than $1 billion is being invested in California to increase the state&rsquo;s RNG supply, mostly private investments. By January 2024, the report predicts, 160 RNG production facilities will be operational within the state. As of April, there were 110 operating RNG production facilities across all of North America.
Further illustrating the industry&rsquo;s incredible momentum during the past decade, Johannes Escudero, executive director of the RNG Coalition, points out that the first RNG project was developed nearly 40 years ago at the Fresh Kills Landfill on Staten Island, New York, and from then until 2011, only 30 additional RNG projects were developed. &ldquo;That&rsquo;s an average of just one project per year over 30 years,&rdquo; he says. &ldquo;But between 2011 and 2015, building upon our policy advocacy successes, the industry quadrupled its annual project development average from 1 to 4. In 2015, we announced an objective to double the number of projects from 47 to 100 by 2025. We surpassed our 100 project goal five and a half years ahead of schedule, in July 2019.&rdquo;
And over just the past 12 months, Escudero says, the North American RNG industry has developed more projects than it did during its first three decades of existence, between 1982 and 2011. &ldquo;That said, we are only proud to the extent we are looking back, and our focus is fixed on the future and our recently announced Sustainable Methane Abatement &amp; Recycling Timeline (SMART) Initiative, an initiative to capture and control the methane from more than 43,000 aggregated organic waste sites in North America by 2050. We are currently working with our membership developing an action plan to achieve this that includes benchmarks for 2030 and 2040.&rdquo;
As for bright spots in further building out the industry, Escudero says landfills still represent the largest, stationary feedstock, so it continues to be the lowest-hanging fruit from a development standpoint. &ldquo;However, due to the environmental and economic incentives included in recent policies, there is an increased effort to develop RNG production facilities from livestock waste (primarily dairy manure) and wastewater treatment facilities,&rdquo; he says. Landfill Gas to RNG Currently, there are roughly 636 on-site landfill energy generation projects in North America, with 450 additional project candidates, according to the RNG Coalition.
The U.S. EPA&rsquo;s Landfill Methane Outreach Program, which tracks projects via its Landfill and LFG Energy Project database, indicates landfill-gas-to-energy projects are operating in 48 states, roughly 75% of which generate electricity. Breaking down numbers for the U.S., there were roughly 399 operational LFG-to-electricity projects operating in August, 99 direct-use projects, 58 RNG pipeline injection and nine RNG local use, according to LMOP data.
For project partners Fortistar and Rumpke Waste &amp; Recycling, RNG represents major investments in the waste management and renewable fuel sectors. A joint project under construction at the Noble Road landfill in Shiloh, Ohio, marks the fourth of 12 new Fortistar RNG projects totaling nearly $500 million in investments over the next three years.
The $33 million Noble Road Landfill project will capture and upgrade landfill methane into RNG to be distributed through Chesapeake utility Corp. affiliate Aspire Energy&rsquo;s pipelines. The RNG will be dispensed at natural gas vehicle fueling stations, totaling 6.9 million gallons of gasoline gallon equivalents per year, enough to fuel 725 trucks.
Recently beginning operations is the South Shelby Landfill RNG project, a three-way partnership of Republic Services, Aria Energy and BP. The 4,000 MMBtu-per-day facility marks Aria and BP&rsquo;s fourth RNG project at a Republic Services Landfill and is one of 69 Republic landfill gas projects. The facility can produce the equivalent of nearly 33,250 gallons of gasoline daily. Aria operates the project, processing and purifying biogas from the landfill into RNG, with BP transporting the RNG into the interstate natural gas pipeline to market to customers. &nbsp; Wastewater to RNG Because wastewater treatment plants (WTTPs) generate biogas with high methane content and very low nitrogen and oxygen, they are attractive candidates for RNG projects. Some wastewater treatment facilities treat sewage sludge on-site using AD, while some send it to other facilities for processing. Approximately 13 WWTPs had operating RNG projects in 2019, according to LMOP.
That number has increased, as Tetra Tech Inc., CGRS Inc., and the city of Boulder have recently completed what has been dubbed the Biogas Use Enhancement Project. A main impetus in moving forward with the project was that facility&rsquo;s cogeneration system, which has been replaced with a new digester gas upgrading system, was at the end of its useful service life. Western Disposal has agreed to purchase the RNG to fuel a portion of its vehicle fleet of approximately 31 trucks, according to the city, which plans to take advantage of renewable identification number (RIN)-earning opportunities under the U.S. Renewable Fuel Standard, potentially driving a return on investment in the next 10 to 15 years.
Another example of a new WWTP-to-RNG facility is the city of Phoenix 91st Avenue Wastewater Treatment Plant. There, Ameresco designed, built, owns and operates the largest wastewater treatment biogas-to-RNG facility of its kind in the U.S. The plant, capable of processing raw biogas at a rate of 3,250 standard cubic feet per minute, sends RNG through a three-mile RNG pipeline connected to an interstate natural gas pipeline. The RNG is sold on the open market as vehicle fuel under the RFS. The project is expected to generate $1.2 million in annual revenue, to be shared among the cities that jointly own the wastewater treatment plant. Manure to RNG According to the EPA AgSTAR project database, as of March 2020 there were 255 operational digester projects utilizing livestock manure in the U.S.&nbsp; Nearly 80 percent of these are at dairy farms, 14 percent are at hog farms, and the remaining&nbsp; utilize mix of animal manure, including poultry and beef cattle. Most of these projects generate electricity&mdash;roughly 84 percent&mdash;and many also recover waste heat for cogeneration. More than 20 manure-based digester projects are currently producing RNG from their biogas, with a variety of RNG end uses including electricity, vehicle fuel and pipeline gas.&nbsp;&nbsp; The RNG Coalition asserts there are 8,000 large farms and dairies are potential candidates for ag waste/manure-to-RNG production. &nbsp;
Perhaps one of the best-known projects is Monarch Bioenergy, a joint project between Roeselein Alternative Energy and Smithfield Hog Production. It has the purpose of initaiting RNG production across all Smithfield&rsquo;s hog farms in Missouri, resulting in approximately 1.3 million dekatherms of RNG annually, the equivalent to eliminating 130,000 gasoline vehicles.
Smithfield is also involved in RNG project through its joint venture with Dominion Energy, Align Renewable Natural Gas. Located in Duplin and Sampson counties in North Carolina, the project will generate enough energy to power more than 3,500 homes annually upon completion. As part of the initiative, RNG production will be installed across as many as 19 area farms. The project is modeled after the Optima KV project, which captures biogas on five Smithfield contract farms in North Carolina, and similar projects on Smithfield farms in northern Missouri and Utah.
Another notable project is that of Calgren Dairy Fuels. Early this year, Calgren and Southern California Gas Co.&nbsp; announced that four additional Central Valley dairies have begun sending methane produced from cow manure to Calgren's biogas-to-RNG operation in Pixley, California, for injection into SoCalGas' system. The Calgren cluster project now processes manure from more than 66,000 cows at 10 area dairy farms.&nbsp; The additional dairies are projected to nearly double the amount of RNG produced at the facility. &nbsp;&nbsp; &nbsp; Food Waste to RNG The EPA reported in its 2018 AD survey results that of the 43 stand-alone organic waste-using facilities that disclosed their biogas end use, just five produce RNG for company vehicles or for sale to other customers, while none provide RNG for pipeline injection.
One of the relatively few food waste-to-RNG projects is CR&amp;R Environmental Services&rsquo; AD project in Perris, California, which uses residential and commercial yard and food waste. Though the project has an initial maximum capacity of 83,600 tons per year, additional phases are planned to build out capacity to four times that amount.&nbsp; In 2018, CR&amp;R began injecting RNG into the SoCalGas fossil natural gas system via a newly built 1.4-mile pipeline, which CR&amp;R extracts the RNG back out of to fuel about 400 of its waste-hauling trucks. Moving Forward As for North American industry growth moving forward, Escudero says that first and foremost, public policies are driving industry growth. &ldquo;Public policies influence markets, markets drive demand,&rdquo; he says. &ldquo;Additionally, as the general public becomes better educated about the environmental and economic benefits of RNG&mdash; including recognition of RNG as a waste management solution for organic waste materials&mdash;the call for public officials to support pro-RNG policies like the RFS, LCFS, and state renewable portfolio standards increases.&rdquo; &nbsp;
The calendar year is nearing a close, Escudero adds, and despite the uncertainty the past year has brought, the future for RNG looks bright. &ldquo;This uncertainty&mdash;politically, socially, environmentally, economically&mdash;is likely to continue into the foreseeable future,&rdquo; he says. &ldquo;That said, we are eternally optimistic. We consider ourselves very fortunate as an industry to provide energy as an essential service. As the industry advocate and representative, we are grateful for the personnel, systems and practices, relationships and membership support that have enabled us to advance our mission, even during these unpredictable times.&rdquo; Author: Anna Simet Editor, Biomass Magazine 701-738-4961 asimet@bbiinternational.com

RNG Revolution

Minimizing costs has always been a top priority for pellet producers, but today&rsquo;s economic uncertainty underscores the urgency for companies to thoroughly evaluate methods of reducing waste&mdash;that is, regarding wasted efforts, wasted energy and wasted product.
In fact, 60 percent of production activities in a typical manufacturing operation are waste, according to research by the Lean Enterprise Research Centre. The eight forms of waste are defined as waiting, unnecessary transportation, unnecessary motion, inventory, extra processing, defect, overproduction and unused talent. &ldquo;Elimination of these eight forms increase the value generated for the company and the consumer, but more importantly, provide sustainability of the natural resource by avoidance of the depletion of the resource,&rdquo; says Justin Price, P.E., principal of Eugene, Oregon-based Evergreen Engineering. &ldquo;For me, when a producer wants to minimize cost, we typically look to the lean manufacturing principals and look to eliminate the &lsquo;eight wastes.&rsquo;&rdquo;
One of the major challenges pellet producers face is moisture monitoring and control of incoming feedstock, proper control of which can reduce or eliminate problems down the process line. Sarah Hammond, marketing manager of Sarasota, Fla.-based MoistTech Corp., notes with implemented moisture monitoring, manufacturing and processing plants can find huge money savings in a short of time. Managing Moisture &ldquo;Immediate results can be seen from reduced transportation costs from excess moisture, savings in water usage from dust suppression and cleanup, less wear and tear on equipment die to ash and dust buildup, and preventing blockages on the conveyor resulting in shutting down the boiler,&rdquo; Hammond says.
When looking at the many challenges pellet plant operators are tasked with, moisture control is one of the biggest. Hammond notes sensing moisture in wood pellets is one of the most important steps, especially after manufacturing when pellets are stored. &ldquo;Moisture control in pellet plant design is a crucial implementation in proactive avoidance of quality control issues,&rdquo; she says. &ldquo;Moisture sensors are recommended to be installed in several locations throughout the process to achieve ultimate efficiency.&rdquo;
Dryer effectiveness is critical, and because dryers use a lot of energy to run, installing a sensor prior to the dryer will monitor the moisture levels going in and also provide better control over the dryer&rsquo;s temperature, according to Hammond. &ldquo;Too dry of a product will result in over drying, causing a dusty, ambient environment, but could also result in a fire,&rdquo; she says. &ldquo;Installing sensors after the dryer and prior to the pelletizer will result in significant cost savings. Product that is too wet could cause the pelletizer to plug up which results in the line shutting down and product being wasted.&rdquo;
Manufacturing wood pellets requires the refining, drying and blending of wood waste prior to entering the pellet press. By integrating MoistTech&rsquo;s IR-3000 into the process, Hammond notes, producers can monitor 100 percent of their product quality, instantly and consistently. &ldquo;Measuring moisture throughout the wood pelletizing process will produce pellets at a specific moisture percentage, preventing them from being off-spec when the product is too wet or too dry,&rdquo; she adds.&nbsp; &ldquo;Additionally, pro-active adjustments can be made to the process, to optimize pellet manufacturing. The higher the moisture content of incoming purchased wood fuel results in overpaying. The overuse of dryers results in overpaying on energy costs.&rdquo;
Hammond gives the example of an MDF manufacturing client having issues with a moisture gauge that would continually fail due to high temperatures, thus delaying production. Installation of an IR-3000 moisture gauge with a vortex cooling panel solved the problem.
Moisture measurement is just one component of many that add up the big picture. The key players in the industry have figured out how to balance capital investment with operating costs and take advantage of technology and designs that maximize automation and increased reliability, an example of which would be an automated wood yard, says Ken Upchurch, vice president of sales and marketing at Bruks Siwertell. &nbsp; Material Sizing, Conveying &nbsp; &ldquo;Reducing the manpower and equipment used in a 500,000-ton-per-year plant can be significant,&rdquo; Upchurch says. &ldquo;The typical operation is under 24/7 demand. Through automation, staffing can be reduced significantly. In addition, high-energy equipment such as dozers can be eliminated. The cost savings on an annual basis can easily exceed the $1 million threshold.&rdquo;
Price notes that for large pellet manufacturing operations&mdash;those producing more than 300,000 metric tons per year&mdash;should evaluate having their own chipping operations to save money, while smaller mills typically purchase chips, sawdust or other residuals.
Judi Tyacke-Rawlings, project manager at Missoula, Montana-based Rawlings Manufacturing, says the company&rsquo;s machines are designed to run 24/7, and this continuous operation helps minimize costs. &ldquo;We are the very first grinder in a pellet mill, either the horizontal version or the vertical hogs, and we are completely different than hammermills, as we can handle contaminants,&rdquo; she says. &ldquo;Our machines go up to 90 tons an hour, and we take it down to 2-inch minus. They have a solid, complete steel rotor, which allows us to be a heavy-duty primary grinder without causing a lot of damage to the machine.&rdquo;
Because the machines run at lower RPMs, it saves money on electricity and requires less maintenance, as parts wear out slower than those running at 1800 RPMs, Tyacke-Rawlings says.
Moving on from drying to moving material, it is imperative to get conveyor transitions designed and installed correctly. This, Price says, is the area where he sees the largest fiber waste. &ldquo;To put this in perspective, if you put one hand in a bucket of ice, and the other on a hot stove, the average is great but neither hand is a workable situation,&rdquo; Price says. &ldquo;We see this most often in conveyors handling large surge loads&mdash;for example, truck dumpers. The conveyor from the discharge of these devices needs to be sized for the peak loading on the volumetric and mass basis.&rdquo;
Bruks Siwertell recently worked with Canadian wood pellet manufacturer Barrette-Chapais on its 210,000 metric-ton-per-year wood pellet facility at the Port of Saguenay facility in Quebec, installing a Bruks Siwertell air-supported conveying system. With a rated capacity of 800 tons an hour, the system is comprised of a 100-meter Bruks Belt Conveyor and a 250-meter Tubulator, which uses air support to deliver low-friction conveying, the major benefit of which is preservation of product quality.
In a nutshell, the belt conveyor carries material from the facility&rsquo;s two pellet storage domes that utilize a gravity reclaim system to discharge pellets onto the Tubulator system. This ultimately feeds it to the ship loading operation.
The Tubulator employs Bruks Siwertell&rsquo;s suspension cable tower technology, reducing foundation requirements and minimizing construction costs. According to Bruks, the Tubulator can achieve capacities up to 40 percent higher than comparable conventional idler belt conveyors.
&ldquo;It is critical that transport conveyors protect the pellets from outside environmental conditions as they are delivered to the ship,&rdquo; Upchurch says. &ldquo;The air-supported design required less capital due to the quantity of structural steel required as compared to other designs, and this design also required less moving mechanical componentry, equating to lower maintenance and operating costs.&rdquo;
Upchurch notes that air-supported conveyors can be considered advantageous in many but not all situations. &ldquo;The application that favors air supported technology is one that requires a fully enclosed conveying systems with transport capacities that are moderate to high,&rdquo; he says. &nbsp; Drying Details For drying systems, the most important aspect is moisture control of the final product, according to Price, which he says is done through proper management of raw material, as well as understanding the seasonality of the wood, weather and source.
&ldquo;Another aspect is understanding the effect the fuel has on the drying,&rdquo; he says. &ldquo;For many large-scale pellet plants, waste wood or hog fuel burners are used to generate the hot gas for drying. If the fuel has a high moisture content&mdash;roughly greater than 68 percent MCwb (wet bulb moisture content)&mdash;natural gas or another fuel is often used as an overfired fuel to sustain combustion and achieve the desired energy.&rdquo;
There are several other operational factors to consider in the energy plant and drying areas&mdash;the effect of excess air after combustion on the combustion burner efficiency, for example. The greater the excess air, the less efficient the burner becomes, and the greater the fuel consumption. &ldquo;You can also expect that, as excess air after combustion increases, the gas flow rate through the dryer will increase,&rdquo; Price says. In turn, this increase decreases the moisture content of the material existing the dryer.
Dryer exhaust temperate has a significant impact on the thermodynamic of the dryer and the drying efficiency, Price says. &ldquo;Drying efficiency will ultimately have effects on the boiler efficiency. In some instances, an increase in the dryer exhaust temperature is accompanied by a decrease in the boiler efficiency. This decrease is generally due to the loss of energy from the system, energy that leaves the dryer that otherwise would have been used for drying.&rdquo; Avoiding Overspending When working with producers, Price typically selects multiple facilities within their organization to benchmark the operations, but if the producer only has one facility, then he focuses on the capacity or equipment capabilities. &ldquo;In both methods, we focus on cost reduction through a well-directed review of the process, operations and procedures,&rdquo; he says. &ldquo;With our plant engineering, maintenance, and operations background, we help producers gain efficiency with the goal of increased margins.
Outcomes of these operational reviews identify opportunities, develop budgets for cost-effective solutions, and formulate long-range plans to mitigate current and prevent future bottlenecks.&rdquo;
Evergreen Engineering focuses on results in what it dubs the &ldquo;$5 dollar, $5,000 dollar, $50,000 dollar and greater&rdquo; solutions. &ldquo;Many of the solutions we bring are simply related to waste elimination,&rdquo; Price says. &ldquo;More often, we find a lack of maintenance being the most common reason producers aren&rsquo;t meeting the production requirements in the front-end of the pellet plant.&rdquo;
Price says the best advice he can offer about not wasting money on a job is to understand the process needs and focus on the equipment best-suited to meet those specific needs. &ldquo;Find a trusted resource that has experience with the wood products industry and its operational challenges to help in the technical evaluation of the equipment, and its design advantages and disadvantages,&rdquo; he says.
The industrial pellet market has evolved significantly over the past decade since the original high-capacity production facilities were built in the U.S., and many have learned how best to save money. &ldquo;More often than not, they have been successful,&rdquo; Upchurch adds. &ldquo;This success has come with some learning moments, but there are several producers that have optimized the front-end process. As the market evolves, I am certain production costs will continue to be closely scrutinized. It is important that we learn from those that have been successful and collaborate as an industry to always look for best practices and technologies.&rdquo; Author: Keith Loria Biomass Magazine Freelance Writer www.biomassmagazine.com freelancekeith@gmail.com
