Packaging goes green.

PACKAGING GOES GREEN

More and more packaging suppliers are producing recycled products that protect the environment and their costs. Today, many products are described as being either manufactured from recycled material or are themselves biodegradable. This trend has not been lost on producers of packaging products.

"It is becoming a mandate from everyone from large corporations to small companies, to use environmentally friendly packaging," said Jim Lee, marketing and sales manager of Western Pulp Products.

Western Pulp, based in Corvallis, Ore. has been using recycled paper to produce its package protection products since its inception in 1957. Only then, the company did not use recycled paper to save the planet, said Lee. It did so because it was economical and it produced a tough product.

"If you can provide the packaging at a low cost and it happens to be pro-Earth, that's a plus," said Lee.

But, Western Pulp is not the only "green" packaging supplier. Many companies promote this fact heavily as is evident in the product roundup at the end of this story.

In January, Dow and Sealed Air Corp. announced a national program to recover polyethylene cushion materials. The two companies have been purchasing the scrap cushion packaging from their respective customers. In time they say they hope to expand the program and involve other companies. The two companies set a goal of recycling 5 million pounds over the next two years. Since the beginning of the year 1.3 million pounds have been recovered.

The material collected will be converted into a polyethylene resin to be shared by both companies to produce products with a recycled content. Dow Plastics will be using this resin to make ETHAFOAM products. Sealed Air is recycling the resin into Poly Cap R, which is a recycled bubble cushioning material.

"This program is intended to accomplish a number of things for both Sealed Air and Dow," said Ken Harman, business director for Resource Conservation Division of Dow. "First, it will divert waste polyethylene from the solid waste stream and return it to useful products. Second, it will provide both companies with an ongoing source of consistent-quality recycled resin. Finally, it will allow us both to provide our customers with products containing recycled content."

A recycling program is also in the works at Haworth Inc., one of the nation's leading office furniture manufacturer based in Holland, Mich. The company worked with Michigan State University's School of Packaging in developing a new way to protect its products using less cardboard.

MSU researchers developed a plastic spacer block that fits between panels, and in theory, eliminates most of the cardboard material now used. Haworth anticipates that the spacer blocks will eliminate the need for at least 40,000 cartons a year. It is currently in the field test stage said, Richard Planck of Haworth. He did not know when the tests would be completed.

Haworth is also packing orders in bulk, a policy which could eliminate 298 tons of trash -- or 37 semi-trailer loads of material -- from ending up in landfills.

"When we can better our product, reduce environmental waste and make things easier for our customers, everybody wins," said Richard G. Haworth, president and CEO of Haworth Inc.
