Was 3: Composting

Credits Available: 1 (no mandatory elements)

A single credit can be awarded for the provision of facilities to enable waste composting. Composting reduces the amount of material destined for landfill. By reducing the amount of organic materials entering landfill sites the production of landfill leachate and methane gas (produced by their decomposition) can be reduced. Leachate is toxic and can contaminate water supplies.

Garden based composting facilities should be provided to enable composting of green waste, garden waste, food and other compostable household waste. Dwellings without gardens should have a Local Authority kitchen waste collection scheme or a community based composting service in place to qualify for the credit. Information on their operation should be made available to inhabitants.

Credits are awarded based on the criteria outlined in the table below.
