028090-000000-0000002 Scope
2.1 This procedure provides a framework for the evaluation and validation of Defined Source material content claims in manufactured products when such claims are based on segregated material flows (Section 12) or on a credit account or allocation system (Section 14). Requirements for Chain of Custody between sites (Section 13) are included and applied when transferring material between multiple facilities. Not all sections of the standard will apply in every evaluation. Segregated material flows or mass balance accounting may be used when evaluating any Defined Source of material. The method(s) used must be included in the claim. Claims typically consist of the manufacturer indicating either an average percentage or minimum percentage of content. This procedure identifies and addresses all substances included as part of the product, part or material.
2.2 Sections 6, 7, 8, 9, and 10 define special requirements for each defined source of material. Those requirements only apply to the target defined source material content. Sections 12, 13, and 14, are used depending on the supply chain and processes occurring at the locations in the supply chain. Some examples for appropriate use are given below. The example is not exhaustive of activities and organization of supply chains for recycled content and should be used as illustrative of general principles for applying Sections 12, 13 and 14 to operations within a supply chain. Other combinations are possible and likely to be found in practice.
2.3 In the diagram above the concentration of recycled content is determined at the Granulating-Compounding operation and sites before and after that operation do not change the concentration of recycled content. Batches of material are processed and managed separately so each batch has a known concentration and source of recycled content. Section 12, Segregated Management of Materials, applies to the Granulating-Compounding site while transfer of the material to Forming and Assembly require Section 13, Chain of Custody.
2.4 If materials were managed using a credit system at the Granulating-Compounding site then Section 14, Allocation System, would apply and again Section 13, Chain of Custody, would apply for following sites in the supply chain.
