The document summarizes an automatic separation plant for municipal solid waste using two parallel autoclaves. The plant breaks down waste into recyclable materials, cellulose fibers, and inert mud. Recyclables are cleaned and sterilized while organic materials are converted into cellulose flock that can be used for energy production or as a raw material. Less than 10% of waste is discharged after selection. The system is modular and profitable with minimal operating costs and complete energy autonomy.
