A Wisconsin biogas facility is about to get into another green business: algae.
Canadian company, Solutions4CO2 has just inked a deal to bring its proprietary Integrated Biogas Refinery (IBR) system to Vir-Clar Farm Power's already operational biogas facility in Wisconsin. The new system promises to increase the concentration of methane output while adding a new potential revenue stream to the mix: algae.
With slow returns and a tough regulatory climate, biogas has fought an uphill battle in North America. “Solutions4CO2 provides AD developers with real solutions to these economic and environmental challenges,” said Douglas Kemp-Welch, S4CO2’s Chief Executive Officer.

The process of anaerobic digestion traditionally produces gas containing roughly 60% methane, 39% Carbon dioxide (CO2) and 1% hydrogen sulfide (H2S). Solutions4CO2's Integrated Biogas Refinery separates CO2 and H2S from methane by dissolving it into solid form, benefitting the system in two ways. First, it allows for a more concentrated methane stream, resulting in increased power generation. Second, the newly separated CO2 and H2S are used to produce algae biomass, whose by-products are sold on the open market.
Algae's future as a biofuel may still be up in the air but as many producers already know, there is a growing market for its nutraceutical and pharmaceutical co-products. If all goes as expected, this increased efficiency coupled with the new revenue will cut average new project payback times by more than half.
