A key discussion point for the GCCA at COP24 included recarbonation – where concrete can play a role in tak- ing CO2 out of the atmosphere – as well as other poten- tial important related measures for the purposes of IPCC implementation. "The GCCA exists to drive advances in sustainable construc- tion whilst demonstrating industrial sustainable leadership in cement and concrete manufacturing. We are working to enhance the sector's contribution to global developmental challenges," Lorea noted. Launched in January 2018, the GCCA, which represents cement producers from across the world, recently launched a global work program, sustainability charter and guide- lines toward its commitment to a positive contribution on global sustainable development. Lehigh Plant Seeks Approval for Alternative Fuel Lehigh Northeast Cement Co. could burn "raggertail" as alternative fuel at its Glens Falls, N.Y., plant under a new draft air pollution permit being considered by the state Department of Environmental Conservation (DEC), report- ed the Albany Times Union. Described as a mix of 60 percent plastic and 40 percent paper/cardboard fiber, the material meets the state DEC's criteria for use as an alternative fuel product. It will be used to replace some of the natural gas or coal that is currently used in the kiln, said company spokesman John Brodt. The raggertail will come from two paper recycling mills operated by Frontier Fiber near Niagara Falls, N.Y. The plas- tics and paper are residue from the recycling process and normally are disposed of in a landfill, Brodt said. Before preparing its permit modification application, Lehigh conducted raggertail test burns in the summer of 2017 with the permission of the DEC and performed air emissions tests to compare against the emissions from burning coal. These tests found the use of raggertail as a partial fossil fuels substitute resulted in a reduction in total air emissions from the Glens Falls plant, with decreased emission levels for some constituents and only nominal increases in others. Lehigh submitted a detailed technical report on those tests to DEC. DEC granted tentative approval and will base a final deci- sion after a public comment period. Ash Grove Announces Scholarship Recipients Ash Grove Cement Co., a CRH company, selected Matthew Iles and Kaitlyn Watts to receive the company's annual $1,500 intern scholarships. Established in 2007, the schol- arship program recognizes students who successfully com- pleted a summer internship with Ash Grove or one of its subsidiaries and who have a strong interest in pursuing a career in the cement industry. Iles interned for Ash Grove at its Midlothian, Texas, cement plant and is studying chemical engineering at Kansas State University. In addition to his internship at Ash Grove, Iles also served as a volunteer for the Wamego Humane Society and Habitat for Humanity.
