Cement Plant Burns Refuse in Commercial-Scale Demo

September 1, 2004

After samples from several different Illinois mining operations were collected and tested for fuel value, refuse from the now closed Marissa coal mine in Randolph County was used in a commercial demonstration at the Buzzi Unicem cement plant in Greencastle, Ind. Nearly 50 tons of refuse was dredged from the settling pond at the Marissa mine. The material was vigorously air-dried to make it flowable before shipment to the cement plant. About 80 tons of processed material was delivered to the cement plant for a 24-hour demonstration run.
