8 CEMENT AMERICAS • Spring 2019 • www.cementamericas.com CEMENTSCOPE other customers a continuous and reliable supply of SCMs, including quality fly ash and slag cement. MultiCem slag cement is produced by grinding GBFS, a byproduct of steel production, and can be added in the production of concrete and cement. MultiCem slag cement provides strength, durability, improved finish, and consis- tent performance in concrete, and can be used at higher replacement rates than other SCMs, reducing the overall carbon footprint and decreasing the need for landfills. "We are targeting both large and small markets, where the supply of fly ash is currently constrained, to rapidly deploy our technology," said Scott Ziegler, president of byprod- uct sales at Charah Solutions. "We can be up and running within a few months and produce as little as 30,000 tons or more than 100,000 tons profitably. This compares to tra- ditional vertical roller mills or ball mills that require signif- icant capital investments, need large production volumes to be profitable, and can take years to obtain the necessary construction permits." LafargeHolcim, Town Officials at Odds Over Proposed Air Pollution Law Coeymans, N.Y., officials have postponed a vote on a proposed local air-pollution law that could bar Lafarge- Holcim's Ravena cement plant from burning scrap tires as fuel, reported the Albany Times Union. A vote by the town board was scheduled for Jan. 10 but now the town is considering to send the measure to the Albany County Planning Board for review. State Sen. George Amedore (R-District 46) has thrown his support to a proposal by LafargeHolcim to rewrite the law so the company could burn scrap tires at its Rav- ena plant. LafargeHolcims's regional counsel Shelbee L. Hundley offered up revisions to the town proposal that would allow burning of waste tires, but ban other wastes, like trash, sewer sludge, refuse-derived fuel, electronic waste, and construction and demolition debris. "As the state senator representing the LafargeHol- cim facility, I have great appreciation for them as an employer and community partner," Amedore wrote in a letter to town officials. "At a critical juncture when they could have chosen to leave New York, they showed their commitment to their employees and the commu- nity and decided to invest in their new plant here." Amedore said while he supported Lafarge's proposed changes to the law, he was uncertain as to whether the burning of tires at the plant would call for a full-fledged Environmental Impact Statement under the state Envi- ronmental Quality Review Act, something that backers of the law want to see done. "We should keep politics out of this, and bring in the science," Amedore said, adding that cement produc- tion was a "very overregulated industry." Amedore said he met with proponents of the law prior to deciding to support Lafarge. Burning tires at the Ravena cement plant would replace some of the coal and coke used as fuel to fire the cement kiln, which was rebuilt in 2017 as part of a multimillion dollar modernization projectproject.
