Ball Horticultural Company Selects Mirel Bioplastic For New Soilwrap Plantable Container Application

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Metabolix Inc. (NASDAQ: MBLX) today announced that Telles™, its joint venture with Archer Daniels Midland Company that produces Mirel™ bioplastics, has entered into an agreement to supply Mirel bioplastic sheet grade resin for the Ball Horticultural Company patented Soilwrap™. This is a new concept for a bottomless plant container that was test marketed in June at the twelfth annual LOHAS (Lifestyles of Health and Sustainability) Forum held in Boulder, Colorado. The Soilwrap made with Mirel is a fully biodegradable and compostable plant pot solution for the home gardener.

Ball is a global leader in the horticulture industry, with breeding, production and distribution operations in more than 20 countries around the world. Ball's best-known brand is Wave petunias, which were introduced in 1995 and have become a leading plant brand in the horticulture industry. Wave petunias are available in major retailers and garden centers across North America in easily recognized pink pots. In addition to Wave petunias, Ball offers the Simply Beautiful and Circle of Life brands exclusively to independent garden centers throughout North America.

"Ball is a world leader in horticulture and is committed to building on that leadership by identifying and implementing practical, sustainable solutions for our customers. Mirel fits right into our dedication to promoting the future growth of our industry through new approaches to our business and our products," says Bill Doeckel, General Manager of Ball Innovations, a division within Ball that oversees the development of new sustainable products.

Plastic has become an integral part of horticultural packaging because it is lightweight and easy to shape into plant pots, tags and trays. However there continue to be increasing concerns about the environment and the growing amount of plastics that are piling up in potting sheds, basements and landfills across the nation.

In North America alone nearly 320 million pounds of plastic material is used per year for nursery pots, flat trays of six-pack annuals, and cell packs. Only 100,000 pounds of this plastic material is recycled, according to a 2004 estimate from Penn State University College of Agricultural Sciences.

"A lot of plastic garbage, including plastic plant containers, does not get recycled. It ends up in landfills and that's a problem," said Bob Findlen, Vice President of Sales and Marketing, Telles. "Ball has found an innovative way to use Mirel sheet grade for a new product application and the Soilwrap further validates the sheet market in general for Mirel. Partnering with Ball to demonstrate how Mirel can replace conventional plastics in horticulture is an example of a key target application."

In addition to the Soilwrap, Mirel could also be used for other horticultural products including plant labels and point of purchase signage. As new forms of the material are developed, the product could be used for trays, pots and other horticultural packaging applications.

Mirel addresses the needs of the horticultural industry because it processes on standard plastics equipment and it has excellent surface printability to reinforce the brand owner's image with consumers. Additionally, Mirel has the broadest range of environmental properties in a high performance bioplastic; biodegradable in soil, home compost and industrial composting systems, salt water and fresh water lakes, rivers, and streams. Mirel is an environmentally responsible choice for the horticultural business because it offers a superb combination of physical and environmental properties as compared to other bioplastics.

"The use of Mirel supports Ball Horticultural Company's market leadership in providing sustainable solutions for the horticulture industry and we are directly addressing the global plastics waste problem," said Findlen.
