At the moment, most of Leeds' waste is still buried in the ground. Burying rubbish costs huge amounts of money, and the bill to the Council is going up around £1.5 million every year. The rotting rubbish also creates methane, a powerful greenhouse gas which can harm the environment. This cannot continue. The Council started the residual waste treatment project to identify different options of treating this waste.
The Council are still working hard to help reduce the amount of waste thrown away and to recycle as much as possible. The Council has set new targets to recycle 55% of Leeds' waste by 2016 and a long term target to recycle over 60%. The Council are improving recycling services, especially in areas that did not receive a service in the past.
Even after these efforts, there will still be a substantial proportion of the waste that needs to be disposed of, collected mainly in black bins. This is called residual waste.
