Symphony hails US Environmental Protection Agency report on pro-oxidants
LONDON, March 11, 2024 /PRNewswire/ -- Symphony Environmental Technologies Plc. have commented on this important statement from the US Environmental Protection Agency (EPA).
- Blending plastics with pro-oxidants could be a promising solution, as they accelerate photooxidation to obtain degradable materials whose final ecological and physical footprint are much smaller."
- "In this study, two pro-oxidants, iron stearate (FeSt3) and cobalt stearate (CoSt2), were melt-blended with polypropylene (PP) at concentrations of 1 and 2 wt%.
- After 500 h of aging plastics plates showed significant reduction in melting and re-crystallization points - indicating polymer-chain breaking, rapid depolymerization."
- The study offers a successful approach where benign filler could significantly reduce the persistence of plastic pollution without creating undesired by-products."
