Analysis• When developing a waste management solution,
the following aspects should be considered: – the volume of waste generated– the equipment required– a suitable service schedule – knowledge of waste streams that are
commonly disposed of– identify recycling opportunities

Collection• The waste management solution will indicate
the type of vehicle/s required to service the bin. • Other elements that need to be considered at
the time of waste collection are: –positioning of the bin – the type of bin – the waste stream collected in the nominated
bins, and locks, chains and bars in use

Transportation
• A courier service for waste resources. • Employs a fleet of vehicles to waste and
recycling collections:– front lift trucks– rear lift trucks –hook trucks

Recovery
• Resource Recovery Centers (RRC) or Material Recovery Facility (MRF).
• These facilities sort the waste resources into piles of like materials, the resources are packaged for transportation to the next phase– recyclable items are sent to a recycling
facility–non-recyclable items or general waste is
disposed at landfill.

Recycling / Disposal
• Depending on the type of material, whether it is recycled or disposed of at landfill.
• Recyclable waste is recycled and is diverted away from landfill.
• Non Recycables like General Waste are disposed of at landfill.
