The Disguise The Surprise® dividers are made using a Homo Polymer Polypropylene. It is a number 5 recyclable material.
Propylene homopolymer is the most widely utilized general-purpose grade. It contains only propylene monomer in a semi-crystalline solid form. Main applications include packaging, textiles, healthcare, pipes, automotive, and electrical applications.
PP is 100% recyclable. Automobile battery cases, signal lights, battery cables, brooms, brushes, and ice scrapers are a few examples of products which can be made from recycled polypropylene (rPP).
The PP recycling process mainly includes melting of waste plastic to 250°C to get rid of contaminants followed by removal of residual molecules under vacuum and solidification at nearly 140°C. This recycled PP can be blended with virgin PP at a rate up to 50%. The main challenge in PP recycling is related to its amount consumed—currently nearly 1% PP bottles are recycled, as compared to 98% recycling rate of PET & HDPE bottles together.
