Symphony Environmental Technologies Plc (UK), the degradable plastics and waste-to-energy Group, is recently announced that its wholly owned subsidiary, Symphony Environmental Limited, has launched the World's first d2w™ 100% degradable metalized polypropylene film for snack foods, in conjunction with Organizacion Barcel, a subsidiary of Grupo Bimbo Mexico. This material contains a pro-degradation additive -- d2w™ -- which includes a bio-degradation function to the packaging once their useful life is over. This follows the extensive trials and successful use of Symphony's d2w™ additive in the packaging for Bimbo's bread and other products.
Grupo Bimbo is the largest food company and undisputed leader in the national baking industry in Mexico and many Latin American countries. As per a press statement, the company aims to use metalized polypropylene degradable packaging for all product lines by the end of 2010. As far as the process is concerned, the pro-degradation additive is incorporated to the resin when manufacturing the packaging material; this helps break the long molecular plastic chains. Thus, the plastic begins to degrade as soon as its predetermined useful life comes to an end. This breakdown process is the result of oxidation, and finally, whatever microorganisms are present in the environment, complete the process through biodegradation.
