Impact Bioenergy manufactures and sells community-scale, prefabricated systems that convert food waste, liquids, and other organic materials into renewable natural gas and fertilizer with zero waste. Towards that end, we manufacture and sell portable, prefabricated bioenergy systems that convert organic waste materials into organic plant food and renewable energy with zero waste. Our systems process 25 to 1,500 tons per year of waste materials. Energy can be in the form of building heat, hot water, radiant heat, light, electricity, and prime motion. Plant food can be produced in liquid, dry or compost forms. We are also founders of Community Supported Biocycling, which is a community-based coop system for connecting food waste to regenerative agriculture, job creation, zero waste, energy conservation, renewable energy production, carbon sequestration, and ultimately the circular economy. Our technology helps to build a resilient food system that provides access to healthy, affordable organic food by engaging farmers, food/beverage businesses, communities and governments. We seek to make the world cleaner and more sustainable by empowering communities to generate renewable energy and valuable co-products from hyperlocal organic waste. Our goal is to help our customers and partners reduce operating costs and become leaders in sustainability by delivering decentralized solutions.
