Environmental Energy and Engineering Company (E3) specializes in the production of renewable energy, greenhouse gas mitigation, nutrient sequestration, and zero emission facilities.The firm is developing technologies that meet the needs of municipalities, industry, and agriculture. E3 has a holistic approach towards production of renewable energy that addresses not only the carbon cycle but also the nitrogen and nutrient cycles. The firm is able to produce renewable energy from liquid or solid waste, from dilute swine and flushed dairy manure to concentrated wastes such as poultry manure, yard waste, and the food fraction of municipal solid waste. They have developed a variety of anaerobic digestion technologies to maximize the conversion of solids to biogas and from biogas to biomethane (methane). In addition, they have pioneered the development of zero emission anaerobic digestion facilities that produce no adverse environmental impacts.Using this technology E3 is able to sequester and reclaim nutrients such as phosphorus and ammonia nitrogen, while increasing the nutrient density of the stabilized digested product and can economically produce pipeline quality gas, pasteurized Class A fertilizer with any desired C:N ratio, and reusable water with a reduced salt content. E3âs processes maximize the reduction of greenhouse gas emissions through the production of renewable energy. The reductions include avoidance of greenhouse gas emissions from other waste management technologies such as landfills, composting, or anaerobic lagoons. The reductions also include use of zero emission technologies that allow the siting of facilities close to the source of waste generation and product use to minimize transport emissions.
