Routinely, the Team is asked to evaluate the “compostability” of one feedstock versus another feedstock. This is a task that we take very seriously.Numerous compost recipes have been evaluated by the Team over the years, and successful ones are promoted while the unsuccessful ones are discarded.

In 2010, the Team undertook a very ambitious feedstock study in which we evaluated the water-holding capacity and relative leachability of 6 common compost feedstocks used in Maine. The study, entitled, “A Comparison of the Quantity and Quality of Leachate Generated by Five Compost Feedstocks Exposed to Simulated Rainfall”, helped pave the way for further study to determine ideal compost recipes based upon moisture management and leachate generation and management issues.
