When organic materials are left to decompose naturally in oxygen-free (anaerobic) environments like landfills and manure lagoons, methane-generating microorganisms (“methanogens”) digest some of the material and produce a biogas consisting primarily of methane. Anaerobic digesters allow that process to take place in a closed environment that captures the methane so it can be used in a beneficial way. BTE-CA offers integrated technologies that significantly increase the ability of existing and new anaerobic digesters to capture methane.
When the methane captured in anaerobic digesters is burned for useful purposes such as transportation, heating, or generation of electricity, it leaves CO2 – in the short term, a much less potent greenhouse gas – as a waste product. The net result is a much lower impact on global warming than would have resulted if the organic materials had been left to decompose naturally, without anaerobic digestion, as still is allowed to occur at the majority of the world’s dairy and livestock farms and related operations, urban landfills, and wastewater and sewage treatment facilities.
BTE-CA offers to undertake a confidential pre-project Feasibility Study (FS) (3-4 weeks), at BTE-CA’s expense, with the digester owner/operator’s cooperation in providing small samples of feedstock and digestate, and available data on current digester system performance.
The FS report will provide the digester owner/operator a description of the potential for improvement in digester methane capture obtainable through the iBB System technology. It also will recommend the best mode of connecting an iBB to the digester system and operating the iBB to optimize digester system performance.
BTE-CA offers a variety of business approaches, tailored to the customer. One approach we offer: If, based on the FS report, BTE-CA believes an iBB will have a positive impact on a digester’s methane capture revenues and operating costs (reductions), BTE-CA, entirely at its own cost, will install, operate, and own an iBB at the digester, in return for a long-term contract giving BTE-CA a share of increases in digester revenues and reductions in owner/operator costs.
