enVerde LLC

enVerde can solve challenges many face: costs, wastes, sustainability, and energy security. We use a new advanced waste-to-energy process (eVp™) where catalysts convert carbon wastes (think biomass) into fuel (syngas) and heat. Our syngas is not only a sustainable fuel but an excellent building block for making other green fuels and chemicals from non-fossil fuel resources. The heat from our process is an excellent sustainable energy source that can condition air, generate steam (and power), and heat water or processes. Syngas and heat mean no more problematic burning of wastes. We generate clean energy with many advantages: cost, mobility, feedstock flexibility and availability, speed, scalability, applications, and cost-effectiveness. With eVp™, our industry-experienced team is well-positioned to solve many local and global problems.

Froling Energy

Froling Energy is a mechanical contractor focused on the installation of biomass boiler systems in school buildings and campuses as well as in industrial, commercial and municipal buildings. The cornerstone of Froling Energy’s business is providing customers with top quality, reliable boiler systems that save money and have a positive environmental impact. Our in-house technicians provide our customers with expert biomass boiler installations, system integration and ongoing maintenance. In 2014 Froling Energy introduced a new wood fuel to the New England market: PDCs are screened wood chips with 25% moisture content that are delivered into vertical silos by a blower truck. PDCs have a 35% cost advantage over wood pellets and burn with very low emissions. Compared to green wood chip systems, PDC boiler systems cost less, have a smaller footprint and require much less supervision. PDCs are processed at and delivered from our plant in Peterborough, NH.
