2011:
The Streets Division is planning a pilot collection program for collecting household organics from a select group of households. The number of households will be determined by the funding available in the 2011 Operating Budget. The funding will also determine the start date.

City staff is also looking at the various technologies that could be employed for a digester.

Staff believes that the volunteers are very committed to the program which accounts for the higher than anticipated diversion.
Data was collected from our volunteers for Mater B, the plastic resin producer that provided us with bags for the first six months of the program. They were quite pleased with the response and the information will be presented at a Bio Cycle conference in Portland, OR in April
March, 2012:
City staff has determined that the best location for a digester will be near the Rodefeld landfill. Staff will begin discussions with Dane C...
