Pre-sorting Technologies in a Waste Recycling System

摘要

NKK developed a waste recycling system-a sorting and recovery system for recyclable waste such as glass bottles, plastic bottles, steel cans, aluminum cans and other residue. This system incorporates a combination of different sorting and recovery equipment, including a bag breaker & remover, com- pressed air sorter, and aluminum/PET bottle, plastic, an color-based glass-bottle separators. This paper primarily describes the pre-sorting equipment in the new sorting an recovery system, include- ing the bag breaker and high performance, compressed air sorter.
