Abstract

An automated process for separating and recycling a broad mix of waste material including, but not limited to, paper and flexible plastics. A materials recovery facility (MRF) collects, presorts, and separates into individual commodities the material, then separates partially processed 2D blends from 3D containers, while refraining from any quality control of the 2D blends, and bales the 2D blends. A fiber center receives the bales from the MRF, aggregates the partially processed 2D blends, removes recyclable commodities including flexible plastics from the 2D blends, aggregates each recyclable commodity that is removed from the 2D blends, and forms separate commodity streams of clean paper and clean flexible plastics. Also provided are a related fiber center (and an infrastructure including the center) and at least one computer-readable non-transitory storage medium embodying software for performing the process.

Claims (18)

1. An automated process for separating and recycling a broad mix of waste material including, but not limited to, paper and flexible plastics, the process comprising:

collecting the broad mix of waste material at a materials recovery facility;

presorting the broad mix of waste material and separating at the materials recovery facility the broad mix of waste material into individual commodities;

separating at the materials recovery facility partially processed 2D blends from 3D containers while refraining from any quality control of the 2D blends;

baling at the materials recovery facility the partially processed 2D blends to form bales of the partially processed 2D blends;

receiving the bales from the materials recovery facility and aggregating at a fiber center the partially processed 2D blends;

removing recyclable commodities, including flexible plastics, from the 2D blends at the fiber center; and

aggregating each recyclable commodity that is removed from the 2D blends and forming separate commodity streams of clean paper and clean flexible plastics for sale by the fiber center,

wherein separate streams of clean recycled paper having a purity of at least about 98% and clean recycled flexible plastics are created.

2. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

collect a broad mix of waste material including, but not limited to, paper and flexible plastics at a materials recovery facility;

presort the broad mix of waste material and separate at the materials recovery facility the broad mix of waste material into individual commodities;

separate at the materials recovery facility partially processed 2D blends from 3D containers while refraining from any quality control of the 2D blends;

bale at the materials recovery facility the partially processed 2D blends to form bales of partially processed 2D blends;

receive the bales from the materials recovery facility and aggregate at a fiber center the partially processed 2D blends;

remove recyclable commodities, including flexible plastics, from the 2D blends at the fiber center; and

aggregate each recyclable commodity that is removed from the 2D blends and form separate commodity streams of clean paper and clean flexible plastics for sale by the fiber center,

wherein separate streams of clean recycled paper having a purity of at least about 98% and clean recycled flexible plastics are created.
