Generally speaking, any waste disposal or recovery operation requires an Environmental Permit under the Environmental Permitting Regulations. However certain operations that do not carry risk to the environment or human health are exempt from the full force of the regulations and are only required to be registered as ‘exempt waste operations’. These exemptions cover activities such as composting; baling or compacting waste prior to disposal; storage of certain waste prior to collection (e.g. batteries); and gardening operations such as chipping and mulching.
STFC sites hold the following exemption certificates:
| DL | Chipping and mulching |
| Chilbolton | None |
| Coseners | Cardboard baler |
| RAL | Composter and cardboard baler |
| SO | Composter |
| ROE | None |
