Is your Compost up to date with the latest PAS 100 revision?

After two years of consultation with a variety of stakeholders in the organics industry, the REAL, supported by the BSI, have published the revised quality compost specification, PAS 100:2018. Now in its second revision, the standard has been reviewed in order to make it more robust and improve the quality of compost.

Key changes include:


Research Hub

One notable change to coincide with the PAS revision is the formation of the REAL Compost and Biofertiliser Certification Schemes’ Research Hub. During consultation, organisations suggested changing certain limits in the PAS standard. However, regulatory stakeholders rejected these proposals, due to lack of scientific evidence and consequently, the limits were not changed in the final revision. The hub was developed as a mechanism to source funding from the composting and AD industries that will drive research into the issues that are affecting the sector. In turn, this will produce the evidence that will improve the scheme even further and ensure that it remains efficient to all stakeholder’s needs.

WRM’s Services

All operators will now be audited against the PAS 100:2018 certification and existing PAS 100 producers have until 31st of March to transition from PAS 100:2011. Many composters have already successfully transitioned to the new standard, with the support of WRM’s services.
