Biogas production and associated energy value.
Co-digesting with wasted food and FOG will increase biogas production at a single-source digestion facility, such as a WRRF or farm digester. This is beneficial to the facility because biogas can be used to generate energy which can offset costs. Biogas has many beneficial uses. There is also the added bonus of less wasted food/FOG being disposed of in landfills and therefore less methane gas being emitted to the atmosphere (from landfills).
The original version of the CoEAT tool was published in July of 2010. The tool was updated in 2017 and an accompanying user's manual was also developed. Both the Tool and the manual can be accessed using the links below.
