Based on customer requirements, ISCC offers two chain of custody options for ISCC system users. Materials are either physically segregated in production processes throughout the supply chain (“physical segregation”) or mixed in production but separated in bookkeeping (“mass balance approach”).
Physical segregation along the supply chain:
Deliveries of physically segregated materials and products contain 100% certified sustainable material. Therefore, physical segregation allows for strong claims that directly refer to physical characteristics: e.g. “the product is made from bio-based feedstocks certified to the ISCC standard”.
