Publication status

This PAS has been prepared and published by BSI, which retains its ownership and copyright. The BSI copyright notice displayed in this document indicates when the document was last issued. This edition supersedes PAS 100:2011, which is withdrawn.

PAS 100 is not to be regarded as a British Standard and will be withdrawn upon publication of its content in, or as, a British Standard.

This PAS is not intended to restrict new developments in design and materials. Accordingly, all feedback about it and proposals for future work will be considered. It will be reviewed as and when the technical need arises or after two years, whichever is sooner. BSI reserves the right to withdraw or amend this PAS on receipt of authoritative advice that it is appropriate to do so.

Due acknowledgment is given to the Food and Agriculture Organization of the United Nations (FAO) with regards to 3.23 to 3.27, 3.29, 3.35, 3.39, 3.40, 3.41, 3.50, 3.72, 3.80, 3.81 and text within 4.4.

Presentational conventions

The provisions of this PAS are presented in upright, roman type. Its requirements are expressed in sentences in which the principal auxiliary verb is ‘shall’.

Commentary, explanation (guidance) and general informative material is presented in smaller italic type, and does not constitute normative elements (requirements). Much of this appears as notes in this PAS, each beginning with ‘NOTE’, and other such material appears in the annexes marked ‘informative’.

Conformity and certification

Marking PAS 100:2018 on or in association with compost represents a composter’s declaration of conformity, i.e. a claim by or on behalf of the composter that the requirements of this PAS have been met. The accuracy of the claim is therefore solely the responsibility of the person or organization making the claim. Such a declaration is different from third party certification of conformity with this PAS. Composters should note the Compost Quality Protocol’s (QP) requirement for third party certification when demonstrating that compost derived from controlled biowaste is no longer subject to waste regulatory controls (see Introduction’s 0.2, fourth paragraph).

Contractual and legal considerations

This PAS does not purport to include all the necessary provisions of a contract. Composters and any other parties who use this PAS are responsible for its correct application.

Compliance with a PAS does not in itself confer immunity from legal obligations. Neither does certification of conformity by a third-party.

NOTE 1 In England and Wales, processes that compost controlled source segregated biowastes are required under legislation to have an authorization to operate or register an exemption from authorization. An example of an authorization is an environmental permit (permits include waste management licences and exemptions issued prior to 6 April 2008 when the environmental permitting regulations [7] came into effect).

NOTE 2 In Scotland and Northern Ireland, processes that compost biowastes must have a Waste Management Licence (WML) or register an exemption from licensing (see [8] & [9] for Scotland and [10] for Northern Ireland). For facilities treating Category 3 Animal ByProducts, a Pollution, Prevention and Control Permit (PPC) may be required (see [9] for Scotland and [11] for Northern Ireland).

NOTE 3 The use of composts made from controlled, source segregated biowastes is subject to environmental permitting in England and Wales [7], or waste management licensing regulations in Scotland [8] & [9] or Northern Ireland [10] & [11]. However, see 0.2 of the Introduction of this PAS for circumstances in which composts derived from controlled biowastes may be transported, stored and used without waste regulatory controls.
