WRAP consultation - Projects to examine critical aspects of PAS110

Posted: 1 March, 2013. Written by David Collins

During December 2011 a series of workshops were hosted by WRAP, the Environment Agency and SEPA to obtain feedback on PAS110:2010, the AD Quality Protocol and the Additional Scheme Rules for Scotland (ASRS). A further workshop to discuss PAS110 and the ADQP was hosted by NIEA in Belfast during July 2012.

As a result of these workshops WRAP procured projects to examine the three aspects of PAS110 that had attracted most feedback from the AD industry:

  • The digestate stability (RBP) test;
  • The near universal pasteurisation requirement;
  • The PTE (Potentially Toxic Element) limits.

These three projects are now complete, and each project report includes a number of recommendations that (if adopted) could see changes made to PAS110. WRAP is seeking feedback from the UK AD industry on these recommendations and a number of other aspects of the PAS. This feedback will be forwarded in due course to the BSI-convened Steering Group that will oversee the formal review of the specification. WRAP anticipates that the Steering Group itself will be convened during March or April this year.

Please note that this is not a consultation on a revised PAS110, but on the recommendations from three technical projects that will inform subsequent re-drafting of PAS110.
