Homasote Co. selects Alliant Energy Integrated Services to plan, build cogeneration system

CEDAR RAPIDS, Iowa, Dec. 16, 2002 — Homasote Co., a manufacturer of building and packaging products made from post-consumer recycled paper, has contracted with Alliant Energy Integrated Services to plan and build a cogeneration system at its plant in West Trenton, New Jersey.

The $4.24 million project is set to begin in January 2003 and is expected to save the company as much as $2 million annually in energy costs.

Cogeneration is a highly efficient technology that combines two processes — producing steam, or usable heat — and generating electricity. Homasote requires both to break down recycled paper products into a fluid pulp that is later formed into structural fiberboards. The boards are used in the residential and commercial construction industry, and under the Pak-Line brand in the industrial packaging industry.

“When separate processes are used to produce steam and electricity, roughly two-thirds of the energy consumed is wasted,” explains Chuck Castine, president – Alliant Energy Integrated Services. “Because cogeneration equipment captures and uses heat that would otherwise be wasted, it is far more efficient and clean than conventional separate processes.”

Homasote’s cogeneration system is expected to be operational in October of 2003. When completed, it will generate up to 3,900 kilowatts of power and enough recovered thermal energy to heat the equivalent of nearly 300 residential homes.

Peter McElvogue, president of Homasote says: “We’re pleased to have Alliant Energy Integrated Services on board to handle our cogeneration project. By improving the energy efficiency of our plant, we will reduce the cost of producing our products and improve our environmental performance at the same time.”

“In today’s volatile energy marketplace, corporations — large and small — are looking for ways to improve efficiency and reduce operational costs,” adds Castine. “We are excited that Homasote is looking to our company for the energy solutions they need to do business more efficiently.”

The Homasote Company employs more than 200 people. Its customer base includes architects, contractors, builders, engineers and specifiers, as well as facility managers, hobbyists and manufacturers. All Homasote products are made from 100 percent post-consumer recycled paper. Since its inception in 1909, Homasote has expanded the commercial and residential applications of its unique recycled board and grown sales to more than $26 million a year.
