Information on certification is divided by country to reflect the different regulations prevailing in the UK and the different categories of certification. The category under which a composter applies to join the Scheme depends on whether the composter is interested in supplying it with 'end of waste' status to customers in England/ Northern Ireland/ Wales or Scotland.

The two categories of certification are 'End of Waste', 'End of Waste Scotland'.

End of Waste

In England, Wales and Northern Ireland the certification criteria are the PAS100:2018, the Quality Protocol (CQP) and the CCS Scheme Rules. Compost producers applying to the scheme for quality assurance and 'end of waste' status in England, Wales, or Northern Ireland are applying under the End of Waste (England, Wales, Northern Ireland) category of certification. 

End of Waste Scotland

For composting sites in Scotland the certification criteria are the PAS100:2018, the Scottish Environment Protection Agency's position statement and the CCS Scheme Rules. Compost producers applying to the scheme for quality assurance and 'end-of-waste' status in Scotland are applying under the End of Waste Scotland category of certification.
