In 2013, the Matt Brewing Company needed to find a solution for an excessive amount of suspended solids that created performance issues for its anaerobic digester. Removing those solids upstream of the digester feed created an additional byproduct stream that resulted in a cooperative arrangement between the brewery and the regional municipal waste authority. The effort led to a unique composting solution that saved the brewery disposal fees, kept the waste out of the landfill, and generated a supply of quality compost for landscaping projects at the brewery and local charities.​
