NOW MADE FROM 91% RECYCLED PLASTIC
COMMON QUESTIONS
Waste and residue vegetable oils1 are collected and sent to biorefineries to be upcycled into new materials with virgin-like quality properties2. Once the upcycling is done through different chemical processes a feedstock is obtained3, which is then sent to the different plastic manufacturing companies4. The manufacturing companies process the feedstock into plastic resins5 that are ready to be molded into different plastic packaging6. Following use by consumers, disposed plastic packaging can be removed from the waste stream through recycling and provide raw material for plastic manufacturing7.
In advanced recycling, various resources such as recycled and virgin materials (including bio-based and fossil based) are combined together during the production process. At the end of the process, a single type of plastic is obtained, in our case polypropylene (PP), making it impossible to determine the respective proportion source of each material initially blended together.
Mass balance approach3 is designed to trace the flow of materials through a complex value chain. Since chemically recycled4 or bio-based feedstocks are typically blended in the manufacturing complex, physical segregation of recycled content is often practically and economically infeasible. The mass balance approach makes it possible to track the amount and sustainability characteristics of circular and/or bio-based content in the value chain and attribute it based on verifiable bookkeeping.
GLOSSARY
Chemical Recycling: Is the process by which plastic waste is converted, through a chemical process, into a material that can be used to produce new product/packaging with virgin quality standards.
Circular economy: Our current economy is based on a linear process in which we extract resources from the earth, transform them into products and then eventually they go to waste. Circular economy, instead seeks to eliminate waste, circulate products and materials and re-purpose them into new resources and finally regenerate nature5.
Feedstocks: Feedstocks are raw materials used as either as fuels or as resources in a production process6.
Circular materials: To be considered circular materials it must have contents from existing recycled sources, such as post-consumer products, and/or reclaimed materials such as industrial by-products7.
