摘要： An automated process for separating and recycling a broad mix of waste material including industrial and commercial streams. The process begins by collecting the broad mix of waste material. Optionally, the broad mix of waste material is sorted to remove contamination from the broad mix of waste material. Next, the broad mix of waste material is coarsely shredded. Plastic film is removed from the broad mix of waste material, creating a stream of plastic film and a separate stream of dirty cardboard. Residual plastic is separated from the cardboard stream and included either in the plastic stream or in an independent third stream. The process yields separate streams of a film-rich recycled plastic and a clean recycled cardboard having a purity of at least about 95%. Also provided are a related system and at least one computer-readable non-transitory storage medium embodying software for performing the process.
