What happens to your waste

It is important for everyone to recycle and compost as much waste as possible.

We can recover this waste through treatment technologies to make useful products.​

What happens to your food waste

Food waste is a valuable resource used to generate green energy right here in Cardiff. It creates electricity for local homes, schools and businesses.

Food waste is turned into energy to power our homes using a process called anaerobic digestion. This happens right here in Cardiff.

Check out the video to learn more about the process.

Food waste: did you know?

  • Just one caddy of food waste can power your house for half an hour!
  • Did you know that 6 recycled tea bags can produce enough electricity to boil a kettle?
  • In a year, all the food waste in Cardiff could have filled up 11 Olympic sized swimming pools!

What happens to your recycling

The council collects recycling using a separated system, where materials are split into reusable containers. This has:

  • improved the quality of recyclables, and
  • reduced single-use plastic usage.

Once the council collects your recycling and materials have been sorted, they are reprocessed depending on material type. Watch the videos to find out more:

Manufacturers then buy these materials and make new goods with them.

What happens to your general waste

We do not send waste to landfill in Cardiff.

Instead of sending waste to landfill, we work with a company called Viridor, that turns our waste into energy.

If you would like to see behind the scenes in the plant, why not book a visit to the Viridor site in Cardiff?

What happens to your garden waste

Did you know that your garden waste is turned into compost, which can be used to grow more plants?

By recycling garden waste, we are helping the environment. The environmental impact of recycling garden waste in one year was the equivalent of taking nearly 2000 cars off the road!
