England
Biofertiliser certification criteria in England are:
- BCS Scheme Rules – The Scheme Rules detail how the Biofertiliser Certification Scheme actually operates and include procedures for application to the scheme, product complaint investigation, etc.
- PAS 110 - This specification sets out the technical requirements for the AD process and production of anaerobic digestate, including the minimum quality criteria. It specifies requirements for a Quality Management System (QMS) for the production of digestate to ensure they are consistently fit for their intended uses.
- The AD Resource Framework sets out the end of waste criteria for the production of quality compost from source-segregated biodegradable waste destined for use in designated market sectors. If these criteria are met, the resulting outputs will normally be regarded as having been fully recovered and to have ceased to be waste.
Scotland
Biofertiliser certification criteria in Scotland are:
- BCS Scheme Rules – the Scheme Rules detail how the Biofertiliser Certification Scheme actually operates and include procedures for application to the scheme, product complaint investigation, etc.
- PAS 110 - This specification sets out the technical requirements for the AD process and production of anaerobic digestate, including the minimum quality criteria for whole digestate, separated liquor, and separated fibre.
- SEPA’s End-of waste regulatory position statement for digestate – This sets out SEPA's requirements for digestate to achieve End of Waste. This RPS introduces additional standards, reducing the levels of plastic contained within digestate; the plastic limit is 8% of current PAS 110 limits. This aligns plastic contamination limits with Quality Meat Scotland (QMS) standards.
Wales and Northern Ireland
Biofertiliser certification criteria in Wales and Northern Ireland are:
- BCS Scheme Rules – The Scheme Rules detail how the Biofertiliser Certification Scheme actually operates and include procedures for application to the scheme, product complaint investigation, etc.
- PAS 110 - This specification sets out the technical requirements for the AD process and production of anaerobic digestate, including the minimum quality criteria. It specifies requirements for a Quality Management System (QMS) for the production of digestate to ensure they are consistently fit for their intended uses.
- Anaerobic Digestion Quality Protocol – The Quality Protocol sets out criteria for the production of quality digestate from anaerobic digestion of source-segregated biodegradable waste (biowaste). Quality digestate from anaerobic digestion include the whole digestate, in addition to any subsequently separated fibre or liquor fractions. If these criteria are met, quality outputs from anaerobic digestion will normally be regarded as having been fully recovered and to have ceased to be waste.
