That was the topic of a July 17 webinar presented by the recently established American Biogas Council . Among the ideas presented were:
Biogas (mostly methane) is still leaking or wastefully flared from many landfills, wastewater treatment plants, and livestock facilities, contributing to climate change. When produced or captured and refined to pipeline quality, it is indistinguishable from fossil natural gas. Using anaerobic digesters to produce renewable biogas from these large organic waste streams can displace a significant portion of the fossil fuels that we use today (e.g., see a 2010 study by National Grid ), while at the same time reducing other environmental problems associated with these wastes.
