Burning sludge as a fuel could help cut pollution

15 April 2005, Published under Cement News

Lehigh Cement Co. in Union Bridge hopes to be the first plant in North America to burn pelletized sludge as an alternative or supplemental fuel source to the coal that fires its cement kiln. A plan to fuel a kiln at a Carroll County cement factory with Baltimore sewage sludge would be the nation’s first use of so-called "biosolids" as an energy source - a technology that experts say holds great promise. "People have been trying to do something creative with human waste for a long time," s...

Controversy surprises cement plant managers

12 April 2005, Published under Cement News

Managers of the Ash Grove Cement Co. plant say a controversy over use of industrial slag to make cement at the Holcim Inc. plant near Three Forks is surprising, because Ash Grove has used slag for 41 years. Slag from the Asarco Inc. smelter at East Helena has been in use since Ash Grove opened its plant less than 10 miles away in 1963, said Joe Scheeler, environmental health and safety manager. Slag from Asarco’s accumulation also went to Holcim. Last Monday, two environmental groups and ...

In Montana, Asarco’s extensive slag pile is regarded as a "toxic substance" while it’s on the property of the East Helena smelter, but the exact same material is transformed into a "feed product" with little or no state or federal oversight when used to make cement at the Ash Grove or Holcim plants. The transition from toxic substance to valuable product basically comes about because Asarco is being paid for the slag, according to state officials, and federal laws promote this type of recycl...
