“From a sustainability point of view, we can’t put 20% into landfills with limited space,” said Reece.
At the meeting, city recycling coordinator Bryan Johnson said the city collected about 45,000 tonnes of trash and about 10,000 tonnes of this was food waste. That means 10,000 tonnes of groceries “we could do better than just park them in landfills”.
Digesters can also combat the linear economic mindset of buying, using and disposing.
“It has to be circular,” said Reece.
Committee members received the report with the additional recommendation that the city develop a detailed model for applying the digester to the greater Madison area by a specific date to be determined.
The consultants completed an analysis of available raw materials, or raw materials that could be processed in a digester, in Dane County from sources such as waste carriers, food production facilities, and wholesalers.
Among other tasks, engineers provide a financial analysis of the project to determine its feasibility. To do that, they chose the Yahara Hills Golf Course, which is located across from the Dane County Sanitary Landfill, as a potential location for building a digester facility.
