Green plastic in carton packaging pilot

Tetra Pak has reached agreement with the largest Brazilian petrochemical company, Braskem, to purchase limited volumes of high-density polyethylene (HDPE), derived entirely from a renewable feedstock. The agreement is claimed to be the first move toward using ‘green’ polyethylene in the carton packaging industry.

Braskem expects the world’s first commercial-scale green polyethylene plant, located in the south of Brazil, to come onstream late next year and is targeting first deliveries to Tetra Pak early in 2011. The new facility 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 process will result in an overall reduction in greenhouse gas emissions when compared with the traditional process for manufacturing polyethylene.

Under the terms of the agreement, Braskem will begin supplying Tetra Pak with 5 Ktons per year of green HDPE from 2011, for use in the production of plastic caps and closures. The volume represents just over 5% of the company's total HDPE demand and is slightly less than 1% of its total plastics purchases.

“While this pilot project is a small first step into green polyethylene, it marks another milestone in our sustainability journey … and underscores our commitment to finding new ways to use renewable materials in our carton packaging,” said Tetra Pak President and Chief Executive Officer Dennis Jönsson.

The concept of renewable feedstock is well established within Tetra Pak and the company is active in promoting the use of responsibly managed resources. Tetra Pak is actively involved with the Forestry Stewardship Council (FSC) and is supporting the development of a sustainability certification standard to guide the production of renewable raw materials to supply the green plastics chain.
