Abstract

A system for separating waste by type and collecting the separated wastes, preserving the integrity of the separation during the collection and consolidation, comprising a multi-compartment inside container for the initial separation, an outside container that interfaces with the inside container so that the separated contents of the latter can be dumped into the former, a mobile collection unit that transfers the separated wastes from the outside container to a plurality of bins, again preserving the separation, and transports the waste to a distribution facility. The volume of the separated waste is reduced by the collection vehicle as it is dumped through hatches on the top of the vehicle into chutes that lead to the appropriate bin for that type of waste. The collection vehicle grips, lifts and inverts the outside container, made up of three subcontainers, and then separates them so that each can be positioned over and aligned with a different hatch on the top of the vehicle.
