Thank you for your entry and we acknowledge your passion. While the detailed financial proposal is appreciated, we would have liked to have seen more technical content, as it relates to organic waste collection, specific anaerobic digestor designs, and biogas production/transport/utilization. Due to the technical difficulties and multiple unit operations involved in sorting organics (for digestion) from a collected mixed waste stream, this is never the preferred option compared to collection of source-separated organic waste. Moreover, the anaerobic digestion step itself benefits from a relatively uniform feedstock with respect to process operations and controls. You may want to research the work done in this field on a large scale in the 1960s and 1970s that unfortunately has not worked well.
