Teknor Apex Co., with locations in the United States, Europe and Asia, says its custom compounding expertise has enabled U.K.-based Gumdrop Ltd. to advance its program to divert chewing gum from landfill by converting it into a raw material for thermoplastic elastomers (TPEs).
Gumdrop specializes in recycling chewing gum. Anna Bullus, a designer with a special interest in plastics and recycling, founded Gumdrop in 2009.Having created a program for reclaiming pre- and postconsumer gum for use in material it calls Gum-Tec, the company turned to Teknor Apex to develop and produce compounds from the waste stream generated by the 500,000-ton-per-year chewing gum industry. Teknor Apex says the challenge was to devise formulation and manufacturing techniques for an altogether new type of raw material to produce commercial-scale quantities of compounds that consistently meet the requirements of specific applications, including optimized elasticity, compression set, tensile properties and other mechanical properties, as well as processability. read more >>
