The recovery and disposal of waste requires a permit under legislation with the principal objective of preventing harm to human health and the environment. This
legislation also allows for exemptions from the need for a permit, providing general rules are laid down for each type of exempt activity, and the operation is registered with the relevant registration authority.
The majority of Community Composting groups will be eligible for a T23 exemption (Aerobic composting and associated prior treatment). On some community, on sites such as our Compost Demonstration site additional exemptions
are required to carry out related activities such as treating food waste in a wormery.
All exempt projects need to register their exemption with the Environmental Agency. This is free and may be
completed online. The on-line application is quick and simple if less than 10-ton waste is generated annually and used on site and no farm animal access or animal by products are composted e.g. just allotment waste.
Larger processes will require more thought but the Registration processes is relatively simple.
Projects, which do not meet the requirements of an Exemption, will need to obtain either a Standard Rules Permit or
a Bespoke Permit. There are numerous charges associated with these permits.
