ABSTRACT:
A system uses a single chute in a multi-story building to collect into separate large receptacles different categories of wastes already separated by the tenant for recycling. A turntable carries a large receptacle for each category of waste. Controls on each floor enables a tenant to operate the turntable to position a selected receptacle beneath the turntable to receive a particular category of waste. A microprocessor controller and interlocks on the access doors prevent conflicts between floors. A reciprocating ram automatically compacts the waste in the receptacle after a predetermined number of deposits into the receptacle. The compaction operation is delayed by preset time intervals to avoid conflicts with tenant use. One of those time intervals is proportional to the floor elevation to give waste a time to fall though the chute. The compression apparatus may be arranged to apply different compressive forces to different types of waste and to signal when a container is full.
