Abstract
A refuse material recovery system is shown and described including a blend of automatic material processing by size and density and manual separation or sorting procedures. Overall, the system optimizes recovery from refuse including municipal solid waste, commercial waste, commingled recyclables waste, and demolition waste. The system performs a primary size classification followed by ferrous separation steps, manual separation steps, and subsequent size classification steps. The process also provides separation by density, and eddy current method as well as air knife techniques. The system is further adapted to provide optional diversion capability to accommodate different end uses for recovered materials as a function of current market conditions. The system exhibits the desirable characteristics of efficiency, large capacity throughput, and cost effectiveness.
