Firms dealing with gypsum waste, such as plasterboard and plaster, should be aware of changes to the law regarding its disposal. The disposal of gypsum waste and other waste with a high sulphate content to landfill together with biodegradable waste has been banned in England and Wales since 2005. However, where construction waste contained small amounts (up to 10 per cent) of gypsum, separate disposal was not required. From 1 April 2009, the 10 per cent rule is abolished and any gypsum waste that cannot be recycled and is sent to landfill must now be deposited in a separate cell with non-biodegradable waste. Landfill operators must notify the Environment Agency about any non-compliant load and its producer so that it can take action against those who fail to comply.
