We are commercializing the GasProTM biomethane filtration system. This customer-validated technology removes harmful contaminants from biomethane which would otherwise make it unusable as a renewable energy resource. Confined animal operations (such as dairy farms), wastewater treatment plants, food production facilities, landfills, and other sources of waste biomass produce abundant biomethane. Yet most of this valuable energy resource is wasted due to the cost-prohibitive nature of treatment. Our System removes hydrogen sulfide, water, and other problematic substances in a cost and operationally efficient manner. Additionally, the System creates no hazardous by-products. Instead the filter material is heated and “regenerated” through a patented process, allowing for long term, waste-free biomethane processing. In an era of tightening environmental standards and increased demand for clean energy, the GasProTM represents an important and innovative renewable energy solution.
