Dalton—Protecting the environment is something the flooring industry has
taken very seriously, especially at the mill level as manufacturers and fiber
suppliers have developed methods to recycle post-consumer products into new
floors while at the same time making the manufacturing process have less of an
impact on nature. Shaw Industries has not only been at the forefront of the
environmental push for many years it continues to find ways to divert flooring
materials from the land-fill and make its plants produce less waste and use less
energy. The company’s latest environmental initiative is designed to accomplish
all the above, as it has embarked on a project to convert both carpet and wood
manufacturing waste to steam energy which will be used to power the operations
at its Springdale, Ark., plant.
Gary Nichols, Shaw’s energy manager who is heading up the project, said the
concept, known as gasification, has been in the works for more than three years.
“This is really a bold undertaking for the company; we have never done anything
like this before, although it is something Shaw has been considering for a long
time.” The conversion process that is gasification, he explained, turns
manufacturing carpet waste, post-consumer carpet waste and wood flour—the dust
generated from trimming during laminate manufacturing—into steam. Shaw, which
developed the process in cooperation with Siemans Building Technologies, expects
the gasification facility to be fully operational by the end of 2005.
Steve Bradfield, Shaw’s director of corporate environmental affairs, noted,
this venture will result in a reduction of manufacturing byproducts destined for
the landfill, produce lower emissions at the Springdale plant, and eventually
save up to $2.5 million per year at the facility. In terms of just how much
material the initiative will divert from landfills, Bill Barron, Shaw’s vice
president of manufacturing, said the company estimates it will be approximately
16,000 tons of post-industrial and consumer carpet waste combined, and 6,000
tons of wood flour per year. “This represents a huge savings in terms of
landfill reduction and energy costs,” he said.
“In addition, this project is extremely environmentally friendly in terms of
the cleaner emissions that will result—particularly the tremendous reduction in
sulfur dioxide (SO2).” Nichols noted that even though getting the new
gasification facility up and running is top priority, the company continues to
invest in research to find even more ways to be a friend to the environment and
not a hindrance. For example, gasification uses only the actual fiber. To get to
that stage, broadloom wastes are baled and sent to a grinder where the fiber
gets separated from the filler. Another byproduct, he said, is the ash produced
through gasification. So, Nichols’ team is studying ways to convert these waste
byproducts to useful alternatives. Bradfield said, “It is Shaw’s hope that
sustainable technologies will make future wastes from carpet and other floor
coverings ideal for closed-loop recycling into broadloom or other products too
valuable to burn. “Meanwhile,” he concluded, “gasification offers a high-value,
low environmental impact means of collecting and utilizing carpet and wood
waste.”
