This section contains the basic reference documents that make up the criteria for certification in Scotland. For Biogas plants in Scotland the certification criteria are the PAS110:110, the Additional Scheme Rules for Scotland (ASRS) and the BCS Scheme Rules.   The Checklist which inspectors will use when inspecting your facility can be found under the Certifying Bodies section on this website

The flow chart gives a useful guide as to how the overall process works, the Scheme Rules show how the Biofertiliser Certification Scheme actually operates, and the PAS110:2010 and ASRS contain most of the details of what an AD plant has to comply with to gain accreditation.

The Scottish Environment Protection Agency (SEPA) issued a position statement on 23rd February 2010 which recognises the PAS110 as a valid specification in Scotland, provided certain additional provisions are satisfied and these are covered in the Additional Scheme Rules for Scotland (ASRS). See  details of the SEPA decision.
