The report noted that the partnership aims to transition away from using 100% virgin polypropylene resins in the production of Pigeon nursing bottles. Pigeon is introducing a renewed series of nursing bottles that have been developed using LyondellBasell’s biobased CirculenRenew polypropylene polymers (PP), the report added. These polymers are made from renewable feedstocks derived from bio-based wastes and residual oils, such as used cooking oils.
