"Sites" is the share of the 173 English composting permits that sent the Environment Agency 2024 waste returns and took that code in at least once EA 2024 Waste Data Interrogator. A code an asterisk follows is hazardous.

Open windrow or in-vessel

SR2021 No 2, composting in open systems, lists 34 codes and 20 01 08 is not one of them. SR2021 No 3, closed systems, lists 55 and does include it. Both name R3, R13. In 2024 returns the tonnes at composting sites went under R3 84%, R13 5%, R5 2%, D14 2%, R10 2% WDI 2024.

20 02 01, biodegradable waste from gardens and parks. Plant tissue waste from farms and horticulture is 02 01 03.

Not kitchen and canteen waste under the open-system standard rules, SR2021 No 2: 20 01 08 is not on its list. The closed-system standard rules, SR2021 No 3, do list it.

Want this done for you at the gate?

Byrne Waste Tracking runs in the browser on a phone or computer, with nothing to install. It remembers your carriers and their numbers, offers the waste codes and R or D codes your site uses, checks each load against Defra's rules first, and sends it to Defra automatically once you've linked your Defra account. Byrne Digital Solutions is listed on GOV.UK as a compatible software provider.

£89 per site per month, no contract. Join before 1 November 2026 and nothing is due until 1 November; join from 1 November and you get 14 days free. After that it's £89 a month per site, and there's no card to enter until you start it. No setup fee when you set it up yourself. If a consultant introduces you, any setup fee is agreed through them and you see the amount before you pay anything.

A site in Scotland or Northern Ireland that joins before 1 January 2027 pays nothing until 1 January 2027, the day the duty starts there.
