Quality Protocol (QP) Checker web tool is an online assessment tool which offers users an easy, step-by-step guide to check whether their waste-derived products meet the necessary relevant QP requirements and therefore cease to be waste. Compost Quality Protocol sets out the conditions under which a composted material ceased to be waste. The outcome of the assessment is a report which summarises any compliance issues and outlines areas where improvement is needed.  It is important to note that the report does not represent the certification body’s decision and should be viewed as a pre-application rather than self-assessment tool. The report would need to be presented to one of the appointed certification bodies (link to the CB page) for further validation.
