Four Welsh councils have sent to landfill more biodegradable waste than Welsh Government targets for 2013-14, data from the country’s environment agency indicates.
The four councils that exceeded last year’s allowance were Cardiff, Flintshire, Merthyr Tydfil and Newport.
Even so, some local authorities failed to cut the amount of biodegradable waste sent to landfill for the first time since the introduction of the Landfill Allowance Scheme in 2005.
As a number of local authorities used only part of their allowances, the total amount of biodegradable waste sent to landfill was 23% less than the country’s overall target, and declined 5% in comparison to the previous year.
Those below their allowances were Blaenau Gwent, Bridgend, Ceredigion, Denbighshire, Monmouthshire, Neath Port Talbot, Powys and Torfaen.
The Welsh Government said it will continue to work with these councils to help them to improve but John Griffiths, minister for natural resources, culture and sport said Wales was “leading the way in reducing the waste we sent to landfill”.
“As well as helping councils to avoid landfill taxes, there is a clear environmental benefit,” Griffiths said. “Biodegradable waste in landfill sites produces methane, which is 25 times more powerful than carbon dioxide as a greenhouse gas.”
