REAL has launched a consultation on proposed revisions to the Physical Contaminants & Stones (PC&S) test method.
The PC&S test method currently referenced in PAS100:2018 is being updated following recommendations from REAL’s Test Method Working Group (TMWG). The revision addresses three identified issues; cleaning of physical (plastic) contaminants, reporting and weighing accuracy, and the assessment of ‘sharps’. These changes are designed to improve consistency, reliability, and transparency in laboratory testing, particularly considering forthcoming regulatory changes to plastic contaminant limits.
REAL is inviting all scheme stakeholders to review the proposed changes and share feedback. The consultation will remain open until 31st October 2025, and comments should be submitted via email to thomas@realschemes.org.uk with the subject line: Compost and Digestate PC&S test method revisions consultation.
