This document discusses several vermicomposting operations that failed or had issues. It notes the common reasons for failure include human error, greed, miscalculation, and lack of foresight. Specifically, it describes mistakes made by two companies - Pacific Southwest Farms included using feedstock containing glass shards and a worker death in a compost fire, while B&B Worm Farms and Ecology Farms resulted in millions lost due to using vermicomposting as a façade to collect fees. The document stresses that failure should be a teacher, not an undertaker.
