US: CalPortland has been awarded a US$175,000 grant from the Mojave Desert Air Quality Management District (MDAQMD) to replace a 1999 Terex Bore/Drill rig with a 2019 Caterpillar MD2650 drill. The new drill expects to see a 76% reduction on average in nitrogen oxides (NO_x), reactive organic gases (ROG) and particulate matter (PM) combined. The grant comes from the Carl Moyer Program, which provides monetary grants to private companies and public agencies to clean up their heavy-duty engines beyond legal requirements through retrofitting, repowering or replacing their engines with newer and cleaner ones.

US: The US Department of Energy (DOE) has recognised Better Plants partner CalPortland for achieving an energy intensity reduction goal of 28% since 2010. As part of DOE’s Better Buildings Initiative, the Better Plants Program works with leading manufacturers and water and wastewater treatment agencies to boost their competitiveness through improvements in energy efficiency. The cement producer was presented with an award for its efforts at the Better Plants conference in late September 2019.

CalPortland used DOE programs and software tools to help identify energy savings and accelerate investment in energy efficiency technologies and practices. Additionally, the company performed DOE in-plant training sessions driving innovation, cost savings, and the sharing of solutions company-wide to reach its target.

US: Researchers from CalPortland have published a peer-reviewed study looking at the absorption or carbonation of CO₂ by buildings, pavements and structures made from concrete. The authors argue that this negative effect on CO₂ emissions is not being considered in global, national and regional greenhouse gas accounting methods. The paper calls for focused studies on CO₂ uptake in concrete within the context of its overall Life Cycle Assessment (LCA).

“It is time to further examine the value of concrete in the built environment as a significant carbon sink,” said Allen Hamblen, president and chief executive officer (CEO) of CalPortland. “To do so accurately, we must specifically look at the net effects of CO₂ sequestration in concrete and evaluate all structures over their lifetime within a circular economy.”

The study looks at previous attempts to quantify the effect of concrete carbonation, notably using work by the Swedish Environmental Research Institute (SERI) that examined data from several European countries to develop practical models to gauge the extent of CO₂ uptake by concrete globally in the built environment. Different models estimated that 15 - 20% of CO₂ emissions from clinker production were reabsorbed over the lifetime of concrete structures.

US: CalPortland has been awarded a US$0.34m grant by the Mojave Desert Air Quality Management District (MDAQMD) as a partner in the replacement of a 1987 Trackmobile with a 2019 Rail King RK330 railcar mover at its Oro Grande cement plant in California. The new machine has been chosen to reduce its air emissions in accordance with the California Clean Air Act.

US: CalPortland has held the official opening of a rapid fill bulk cement loading station at the Oro Grande, California cement plant. The loading station is the final part of an upgrade project that originally started in 2008 when Riverside Cement owned the plant. This included two new cement loadout facilities, two distribution silos and a cement grinding mill. The upgrade cost US$58.5m.

“Our engineering staff and the Oro Grande operations team have developed a truck loadout system that is one of the fastest in the industry. The added rapid fill bulk loading stations will prevent long wait times for our customers by reducing the total number of trucks on each loading station, thereby further contributing to reduction of greenhouse gas emissions,” said Allen Hamblen, president and chief executive officer (CEO) of CalPortland.

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.

US: CalPortland has commissioned a new cement grinding mill and distribution system at its Oro Grande cement plant in California. The US$58.5m project includes the construction of the finish ball mill and two new cement shipping lanes with two new distribution silos. It completes a partial plant modernisation program that was originally completed in 2008, prior to the acquisition of the facility by CalPortland. The Oro Grande cement plant was purchased from Martin Marietta Materials in mid-2015.

“The addition of this modern finish mill and efficient distribution system allows the plant to operate to the best in class standards as originally designed. It will help provide the industry with the additional supply required for necessary rehabilitation and rapidly developing infrastructure in California and Nevada,” said Steve Regis, Senior Vice President Corporate Services, CalPortland.

The project began in January 2018 and was constructed by general contractor ThyssenKrupp and sub-contractor TIC (The Industrial Company), in collaboration with CalPortland’s Engineering Services team.

The mill is a Polysius two compartment mill with production capability of around 180t/hr. It is equipped with motor, mill and separator technology as well as cement cooler design technology. The system also employs mechanical conveyance (bucket elevator) to convey finished product to the new silos, reducing its energy requirements. These additional systems are being added to the Oro Grande plant.
