Abstract
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. Control means 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.
