The Landfill Allowances Scheme (Wales) Regulations 2004 (The LAS regulations) came into force in Wales on 1 October 2004, to reduce the amount of biodegradable municipal waste going to landfill sites.
Landfilling biodegradable municipal waste, for example food, paper, and garden waste, can contribute to environmental problems such as leachate production - liquid that drains or 'leaches' from a landfill. It also releases methane, a potent greenhouse gas, which can contribute to climate change.

Landfill Allowances Scheme results
We provide the Welsh Government with an annual monitoring report on 1 September each year.
Local Authorities in Wales submit data to us on a quarterly basis to show us how much biodegradable municipal waste they are sending to landfill and whether they are within their allowance.
Landfill Allowances Scheme visits
During 2007/08 we visited all 22 Local Authorities in Wales to ensure the quality and consistency of the data submitted to us in our role as monitoring authority for the Landfill Allowances Scheme (Wales).
