MINERGY CORP. RECEIVES 2004 INNOVATION AWARD FROM
THE WISCONSIN ASPHALT PAVEMENT ASSOCIATION
— Recycled paper mill sludge used in pavement —

(Neenah, Wis.) The Wisconsin Asphalt Pavement Association presented Minergy Corporation with the association’s 2004 Innovation Award at their annual conference in Madison. The Innovation Award, honors units of government or individuals for their innovative ideas or leadership in the transportation field. Along with OMNNI Associates and North East Asphalt, Inc., Minergy was recognized for participation in the successful development of an asphalt mix design that uses glass aggregates produced from recycling and vitrification (melting) of paper mill sludge at its Fox Valley Glass Aggregate Plant.

Minergy Corporation specializes in the vitrification (i.e., melting) of wastes such as sludges, sediments and soils, into an inert construction glass called glass aggregate. OMNNI Associates developed a hot mix asphalt design which used 10 percent glass aggregate produced from paper mill sludge. The result is a high quality, economical asphalt pavement that was verified by Wisconsin Department of Transportation (WisDOT) Central office for use on WisDOT projects. North East Asphalt, Inc. has successfully used this hot mix asphalt design on WisDOT and private projects.

“The primary reason for the plant and the vitrification technology is to convert the areas abundant supply of paper mill sludge into an inert safe material and save valuable landfill space,” said Terry Carroll, General Manager of Minergy’s plant in Neenah. “With aggregate uses such as this, not only can the asphalt plant use a less expensive raw material, but it saves using other natural resources as well.”

The Wisconsin Asphalt Pavement Association (WAPA) is a Wisconsin Non-Profit association representing the interests of the Hot Mix Asphalt (HMA) industry. WAPA is dedicated to the proposition that high performance Hot Mix Asphalt pavements are in the best interests of the State and its mobility as expressed in its State recognized system of roads, streets and highways.

Since 1998, Minergy Corporation has continuously operated the world’s first facility to recycle paper mill sludge into an inert reusable glass aggregate product. Through 2004, using patented vitrification (melting) technology, Minergy’s Fox Valley Glass Aggregate Plant (FVGAP) has processed more than 1,800,000 million tons of sludge from local paper mills. Recycling this material has saved more than 53 acres of Winnebago County landfill space. Minergy Corp. was established in 1993 as a subsidiary of Wisconsin Energy Corp.
