Waste exemption: T26 treatment of kitchen waste in a wormery

Allows very small-scale treatment of waste from kitchens using a wormery to produce compost. The compost can be spread on land to add nutrients or to improve the structure of the soil.

Type of activity you can carry out

For example, you can compost kitchen waste from your office canteen, along with a small amount of shredded cardboard, to provide a drier fibrous element.

Type of activity you can’t carry out

You can’t treat waste not listed under this exemption.

Types of wastes you can treat

The waste codes are those listed in the List of Wastes (LoW) Regulations. You need to make sure your waste fits within the relevant waste code and description.

Waste code Type of waste
200101 Paper and cardboard
200108 Biodegradable kitchen and canteen waste

Quantity of waste you can treat

You can treat up to 6 tonnes of waste over any 12-month period.

Key conditions

The treatment must result in a stable, sanitised vermicompost that can be applied to land.

Other things you need to know

Animal by-products Regulations – animal by-products can include catering waste from kitchens and restaurants (200108 biodegradable kitchen and canteen waste).

If you are intending to compost animal by-products you may also need approval from the Animal Health Veterinary Laboratory Agency (AHVLA). See AHVLA website. You are particularly likely to need AHVLA approval if you intend to supply compost to other users or use the compost at another place.

You have to exclude farmed animals (includes pet sheep, cattle, pigs or poultry) from the area where the composting takes place and where the compost will be used.

For further information on animal by-products requirements, see the AHVLA website.
