In some jurisdictions, unsegregated waste is collected at the curb-side or from waste transfer stations and then sorted into recyclables and unusable waste. Such systems are capable of sorting large volumes of solid waste, salvaging recyclables, and turning the rest into bio-gas and soil conditioners.

Some transfer stations allow residents and businesses to drop off small loads of waste and recycling, and may perform some preliminary sorting of material. Other transfer stations are places where local waste collection vehicles will deposit their waste cargo prior to aggregation and loading into larger vehicles.
