Himark to construct 3 AD plants in U.S. focused on food waste

By Katie Fletcher | July 23, 2014

Himark BioGas International is expanding its presence in the U.S. through a signed agreement with NEO Energy LLC for the design, construction and start-up of three integrated anaerobic digestion (AD) and fertilizer facilities to convert food waste into fertilizer and renewable energy. Two of the plants will be built in Massachusetts and one in Rhode Island. The decision of these locations was optimal for the company.

“The new environmental laws require businesses to transfer their food waste to energy generating and composting facilities instead of sending them to landfills, so it provided a great economic opportunity for our client to set up the AD facilities,” said Ali Aziz, marketing manager with Himark BioGas.

The AD plants will not only give many area businesses a way to comply with these bans, but will also reduce carbon emissions for the local communities. “Each ton of food waste diverted from the landfill will reduce greenhouse gas emissions by just over 1 ton of CO2 (equivalent),” Shane Chrapko, CEO of Himark BioGas, said in a statement.

The facilities will be designed on Himark BioGas’ patented “IMUS” technology and will produce pathogen-free fertilizer and renewable energy from food waste. “The technology is proven to digest all kinds of waste, including food waste, source separated organics, cow manure, ethanol stillage, slaughter house waste and many more,” Aziz said. “This technology has been implemented with various kinds of feedstock around the world.”

A notable feature of the IMUS technology is its ability to handle contaminated feedstocks containing large amounts of sand, dirt, rocks, plastic and cellulose. Aziz highlighted another unique and patented feature of technology called Clean Slate. “The technology separates non-digestible materials from the waste stream during the digestion process and is essential in reducing the cost of managing heterogeneous waste,” Aziz said.

Aziz explained that this technology helps in the long run by allowing the digester to continuously run without having to be shut down, as well as allowing for maximum energy production without the hindrance of buildup at the bottom of the digester.

As per the agreement, Himark BioGas will act as a technology licensor and owner’s representative on behalf of NEO Energy during the design, construction and operation stages of the plants. The agreement also covers numerous other potential plants that NEO Energy might be developing thereafter.

“The first two facilities will be completed pretty soon, followed by the third,” Aziz said. “Work has already begun on the design and engineering of the AD plants.”
