Energy, Waste Management & Anaerobic Digester Technologies

Energy produced from sustainable and renewable sources is the only ecologically and socially acceptable direction for a prosperous viable future. Our technologies, systems and solutions can be applied to produce renewable energy as well as other commercial-market bioproducts from biomass, including algae.

Anaerobic digestion of biodegradable material is one of the most sustainable renewable energy technologies, decreasing fossil fuel requirements and resolving waste management issues.

Anaerobic digesters utilize bacteria—in the absence of oxygen—to break down biodegradable material (such as material from wastewater, manure, algae, food processors, etc.) to create a biogas (a composition of methane, CO2 and other gases). The methane can be harvested and combusted to generate energy in the form of electricity, which can supply the power grid. Using our technologies, the CO2 emitted from the digester can be captured and be reutilized for on-site production of biomass. Once harvested, the algae can be supplemented back to the digester to produce energy, a closed-loop process.

Our carbon capture, reutilization and sequestration technology drives significant improvements in all stages of anaerobic digester energy production. In addition to scrubbing CO2 from the biogas (which decreases energy value of biogas unless removed), it also makes CO2 accessible for reutilization applications. Algae biomass production reutilizes the carbon and can be offered back to the digester as an incoming feedstock, increasing the processes efficiency, stability and output volume.
