Tetra Pak plans to trial renewable polyethylene for plastic closures for beverage cartons from 2011.
High-density polyethylene (HDPE) made from a renewable feedstock will be supplied by the largest Brazilian petrochemical company, Braskem SA. The agreement represents the first move toward using green polyethylene in the carton packaging industry claims Tetra Pak. ??
The ‘world’s first’ commercial-scale green polyethylene plant, located in the south of Brazil, is expected to come on stream late next year and is targeting first deliveries to Tetra Pak early in 2011. It will use ethanol derived from sugar cane to produce ethylene, which will then be converted into polyethylene, the world’s most commonly used plastic. It is estimated that the alternative manufacturing process will result in an overall reduction in greenhouse gas emissions. ??
