The AD Quality Protocol (QP) and the standard to which it refers (PAS110) plus the Additional Scheme Rules for Scotland were developed at the request of, and in partnership with, industry to provide a mechanism for defining the ‘end of waste’ position for digestate, and to build confidence amongst users of digestate.
Now that the PAS110 and the ADQP are almost two years old, WRAP and the Environment Agency would like to evaluate the documents to ensure that both digestate producers and users remain confident in their achievability and robustness.
The evaluation will initially take place through a series of workshops, at which existing and emerging evidence on digestate will be discussed. Venues have yet to be confirmed, but the dates for these workshops are:
Monday 12th December: Edinburgh
Tuesday 13th December: Bristol
Thursday 15th December: London
The workshops are intended to provide an open forum for information sharing and discussion. Whilst other topics can be covered, WRAP and the Environment Agency are particularly interested in examining and discussing evidence on the following:
1. The pasteurisation and digestate stability (RBP) requirements within PAS110;
2. The acceptable inputs and nominated markets in the ADQP.
If you have information relevant to these areas (whether it tends to support the current approaches or tends to suggest alternatives), please send it through to David Tompkins of WRAP David.Tompkins@wrap.org.uk by Friday 2nd December so that I can make it available to all attendees. You are welcome to submit this information even if you are unable to attend the workshops in person.
Where appropriate evidence is available, changes to the ADQP and PAS110 could be considered. Any such changes would follow the normal PAS / QP development process.
