Abstract: A system and process for sorting and recovery of recyclable materials, and in particular, sorting and recovery of recyclable materials from mixed waste comprising municipal solid waste in a materials recovery facility or “MRF” are provided. Advanced technology and machinery are integrated into a multi-step system and process that are designed to treat contaminated MSW streams to meet or exceed minimum material quality specifications while also reducing and minimizing headcount of sorter personnel. Because the mix of materials in MSW can be so varied and unpredictable, the system and process are designed to effectively sort and recover desired materials from MSW streams having a variety of material compositions.
