SUGAR CREEK, Mo. (Jan. 14)—Lafarge North America is well on its way to solving a logistical problem at its cement kiln in Sugar Creek and should be ready to start test-burning scrap tires there later this winter, according to Environmental Manager Steve Kidwell.
The problem, Kidwell said, was that the fires failed to consume the tires' steel belts, causing a "hairball" of belts that blocked the process. Lafarge has since determined that inserting the tires at another point during production will solve the problem, he said.
Lafarge already uses tires as supplemental fuel at six kilns in Oklahoma, Pennsylvania, South Carolina and Washington.
