US: The Portland Cement Association (PCA) has announced the winners of the 2019 Energy and Environment (E&E) Awards. The awards recognised environmental and community relations projects that were completed in 2018 and were presented at the 3rd Annual Cement and Concrete Fly-In.

The CalPortland Mojave cement plant in California won the Energy Efficiency award for the installation of a new classifier system for its vertical roller mill that increased energy efficiency by reducing fan power requirements. The plant also installed a control system for the finish mill that will maximise performance and help reduce wear on equipment. The classifier installation reduced the finish mill energy intensity by 1.5 to 2.0kWh/t, and the control system reduced energy intensity by 13%. In 2018 22% of the electricity consumed by the plant came from on-site renewable wind energy generation. CalPortland has implemented significant energy efficiency measures and its energy management program has been recognised by the Environmental Protection Agency Energy Star program as the Energy Star Partner of the Year for 15 years in a row.

Roanoke Cement Company and Titan America’s Troutville plant in Virginia won the Environmental Performance award for being the first cement manufacturing plant in the US to receive ISO 50001 certification for energy management of all aspects of energy procurement, design and use. The plant reduced its total electrical consumption by 10% and fossil fuels use by more than 12%. The plant has also implemented an alternative fuels program as part of its certification for the True Zero Waste Program, administered by Green Business Certification and has received silver status achieving a 96% rate of waste divergence from landfills.

Lehigh Hanson’s Permanente cement plant at Cupertino in California won the Innovation award for the installation of a water treatment system reducing concentrations of metals, including selenium, to meet permit limits. Lehigh Hanson developed a treatment system that combined ultrafiltration and reverse osmosis (UF/RO) technology in conjunction with biological treatment technology to remove metals, including selenium and dissolved solids. This ensured applicable effluent limits were met while optimising treatment capacity and efficiency. This treatment system is the first of its kind in the cement industry ensuring that effluent limits are met while, at the same time, limiting the quantity of waste needed to be managed.

Buzzi Unicem USA’s Greencastle cement plant in Indiana won the Land Stewardship award for opening a 4km smooth packed stone trail in conjunction with the not-for-profit People Pathways organisation as Phase 2 of the Putnam Nature Trail. Buzzi Unicem USA staff and People Pathways used heavy equipment for rough clearing and grading of the overgrown former railroad bed and improved and expanded the physical trail. These areas were then landscaped with trees, native prairie vegetation plugs, interpretive signage, benches, birdhouses and other features. Additional nature trail enhancements include placement of wildlife monitoring cameras along the trail, installation of nesting boxes and interpretive signage, and maintenance of the recently completed restoration of native flora installed in 2017 and 2018.

Cemex’s Lyons cement plant in Colorado won the Outreach award for volunteering work by its staff at the Rocky Mountain National Park in Boulder, Colorado, performing campground improvement activities at Glacier Basin Campground by moving rocks and fallen timber and clearing existing fire pits of ash deposits. The plant then introduced a new community outreach initiative by hosting a Manufacturing Day event, providing local students tours of the quarry and plant to increase youth interest in pursuing a vocation in skilled trades. Additionally, the plant teamed up with the Celestial Seasonings B Strong Ride for cancer care and research for an event aimed at increasing safety awareness while fundraising for two local organizations and their efforts to fight cancer.

Bolivia/Mexico/US: The US District Court of Colorado has confirmed compensation of US$36.1m awarded to Bolivian investment company Compania de Inversiones Mercantiles (CIMSA) from Mexico’s Grupo Cementos de Chihuahua (GCC). The arbitration follows a dispute that started in 2011 between CIMSA and GCC about the sales of shares in the Sociedad Boliviana de Cemento (SOBOCE) to Consorcio Cemento del Sur de Perú.

GCC said that it will continue to dispute the ruling and that it would continue to fight the legal case in Bolivia. In 2015 local courts in Bolivia overturned damages imposed by the Inter-American Commercial Arbitration Commission (CIAC) upon GCC.

US: The Cemex Lyons Cement Plant has been recognised by the Portland Cement Association (PCA) with its 2016 Energy and Environment Award for Land Stewardship. Representatives from the Lyons, Colorado unit accepted the award on 31 August 2016 at the PCA’s annual Fall Congress meeting in Chicago.

The Lyons plant’s land-stewardship program for 2015 included limiting invasive plants and weeds and cultivating native plants to attract local wildlife and migrating birds, an effort that was launched at the facility in 2008. The plant also optimised its quarry roads to limit fugitive dust emissions and improve energy efficiency and employee productivity. The plant has previously been recognised by the Wildlife Habitat Council for its diverse environmental programs, including increasing areas dedicated to pollinator plantings and native species to 2.33 acres. On Earth Day, plant employees installed bee boards, bat houses and bird nests.

“Cemex is committed to sustainable practices throughout our operations and to building a better future for our communities through environmental initiatives. We are very proud of our Lyons team and their commitment to land stewardship, and it’s truly an honour to be recognized by the PCA for those efforts,” said Cemex USA president Ignacio Madridejos.

The PCA created the Energy & Environmental awards program in 2000. The PCA awards are given annually to recognise environmental and community relations efforts by cement plants throughout North America. The program is open to any cement manufacturing plant in the region.
