The HORSE, 25 Series Bioenergy System (aka H-O-R-S-E) is designed to scale down the size and cost of anaerobic digestion (AD). This system provides on-site generation of energy from food waste and similar organic materials. This can reduce the environmental footprint of even a single cafeteria or restaurant by offsetting trucking offsite to distant facilities, while also offsetting less sustainable forms of energy with self-generated renewable energy.

HORSE AD25 Series
High-solids Organic-waste Recycling System with Electrical Output
CSB (Community Supported Biocycling)
The 25 Series also produces valuable soil co-products. This means local soil resources are conserved, reducing the need for agrichemicals and providing the local community with a post-consumer food lifecycle. Learn More
Leadership in Engineering
The 25 Series has broken down the complexity and cost barriers seen in other anaerobic digestion systems through the use of our proprietary design, and sourcing the manufacturing and engineering in North America. Our base of manufacturing and support is in the Pacific Northwest. The systems are delivered complete and ready for use. It can be delivered on a trailer to be truly portable for events and festivals.
Anaerobic Digestion Process
The breakthrough that Impact has developed involves a unique anaerobic digestion process coupled with very low energy inputs. It also allows for methane recovery and energy generation. The organic matter output can be recovered and directed to the highest and best use locally. This is a robust and simple AD design, featuring minimal labor and expenses, and a small footprint. Our design creates a circular economy whereby waste and other resources like fuel, fertilizer, and food don’t have to be trucked from one community to another. We are inspiring and enabling people to use proven technologies to move water, carbon, microbes, and organic matter back to the soil. Rarely does an opportunity come along that can positively touch on energy, water, air, soil, food, jobs, and education simultaneously. This one does!
Sustainability and Economic Performance
The HORSE empowers our customers to achieve energy sovereignty and utilize their energy resources to the fullest potential. We can help configure both the energy output and the organic matter output to maximize economic, environmental, and social value. Electrical power with auxiliary radiant heat and lighting is standard but it can also be modified for optional prime power, heat, or hot water. Organic matter as a liquid emulsion is standard but it can also be modified for optional compost, fertilizer, and dried pellets. Gas storage is included to allow daily energy production to match peak demand patterns. Feedstock preparation, power generation, output recovery are integrated into the design. The system is designed to be completely enclosed so there will be no odor associated with food waste, biogas, or digested organic matter.
Maximum Energy Production
15,000 - 105,000 BTU/hour
The energy production is designed for 15,000-105,000 BTU/hour continuously.
Organic Input
960 – 6,700 lbs/week
Organic feedstock input is designed for 960-6,700 lbs/week (440 – 3,050 kg/week).
Organic Matter Output
100 – 730 gallons/week
Produces 100 – 730 gallons/week (400-2,800 liters/week) of liquid organic fertilizer.
The Impact Bioenergy Advantages
We understand that communities and organizations are seeking more sustainable and affordable sources of energy and methods of waste diversion. The best solutions are located at the source, yielding the greatest economic and environmental impact. Our systems are ideally suited to small to mid-size communities, campuses, and commercial generators of organic waste. The 25 Series offers continuous distributed, off-grid energy, reducing reliance on power transmission across the landscape, and providing energy independence and security.
- An ability to reduce disposal, recycling, and energy costs simultaneously
- Minimal space requirements using onsite or local community based systems
- Quick deployment to replace diesel/petroleum gen sets – and easily expandable
- High Performance Visual and Environmental Performance – especially on odor
- Onsite electricity and heat generation, or other forms of energy (lighting, hot water, etc.).
Easy to Deploy and Scale up
The 25 Series prefabricated bioenergy units drive down capital costs and allow delivery and installation quickly. Expansion is simple with minimal space and connection requirements. The 25 Series can convert kitchen trim, post-consumer dining room food scraps, meat, grease, oil, all edible liquids, seafood, dairy products, starch, sugar, fruit, vegetable, small bones, soiled paper products, napkins, tissue, paper towels, waxed paper, grass clippings, leaves, small sticks, lightweight wood tableware (stir sticks, toothpicks, spoons, knives, forks), fats, fryer oil, grease trap waste, beverages, alcohol, soup, condiments, eggshells, glycerin, etc.
