A waste management licence is a legal document issued under the Environmental Protection Act 1990. A licence has conditions to make sure that the authorised activities do not cause pollution of the environment, harm to human health or serious detriment to local amenities.
Controlled waste means household, commercial or industrial waste.
It includes any waste from a house, shop, office, factory or any other trade or business premises. It is controlled waste whether it is solid or liquid and even if it is not hazardous or toxic. Otherwise they could be fined and sent to prison. The conditions of the exemptions from licensing are in the Waste Management Licensing Regulations 1994. If you think your activity may be exempt please discuss this with the Environment Agency.
