Food waste is a valuable resource that can be recycled into compost and fertiliser for agriculture, as well as biogas which can be used to generate electricity or heat.
If food waste goes into a general waste (black) bin, it will end up in landfill. Here the food waste will decompose, producing greenhouse gases including methane. This gas is 25 times more powerful than carbon dioxide in terms of global warming. As a result, sending food waste to landfill has a significant impact on climate change. If food waste ends up in a household recycling (blue) bin, the whole load of recycling can be rejected and sent to landfill instead. Find out more about the climate impact of food waste at BBC Future.
By recycling unavoidable food waste in your green bin* from the City Council or composting at home, you can reduce your greenhouse gas emissions. Food and garden waste from your green bin is taken to the ‘in-vessel’ composting plant at the Amey Waste Management Park near Waterbeach. Here it goes through an intensive and fast composting process, producing soil conditioner which is sold for local agriculture and can also be collected by householders for free.
* Bin colours vary depending on the local authority. The bin colours mentioned here refer to household bins in Cambridge and South Cambridgeshire.

Use a food waste caddy in your kitchen to collect scraps, which you can then empty into your food waste bin. You can line your caddy and bin with newspaper or paper liners to keep it clean. Cambridge City Council sells caddy liners and offers free caddies via their website.
