Energy Star awarded to CalPortland’s Rillito cement plant in Arizona

14 January 2021

US: The Environmental Protection Agency (EPA) has awarded CalPortland’s Rillito cement plant in Arizona with its ninth consecutive Energy Star. Efforts towards energy intensity reduction at the plant included: replacing two preheater tower cyclones, installing 11km of new belting to a quarry belt conveyor, replacing the kiln baghouse fan and dust collector bags, increasing the plant’s focus on energy efficiency by expanding its energy team, conducting more frequent energy meetings and communicating energy efficiency best practices throughout the plant.

President and chief executive officer (CEO) Allen Hamblen said “CalPortland is pleased to accept the EPA’s Energy Star 2020 certification in recognition of our energy efficiency efforts at the Rillito plant. We continue to demonstrate our commitment to environmental stewardship and Energy Star while also reducing our energy costs through the hard work of our employees and our corporate energy management culture.”

CalPortland launches near-zero CO2 truck fleet

17 December 2020

US: CalPortland has launched a new fleet of 24 compressed natural gas (CNG)-fuelled bulk hauler trucks. The company has also commissioned a CNG fuelling hub at its Oro Grande cement plant in California. Ozinga Energy installed the hub, which uses biogenic Redeem methane from organic and agricultural waste at its fast-fill station and 24 slow-fill stations. The producer says that Redeem will reduce CO2 emissions per tonne of fuel burned by at least 70%. It predicted a total greenhouse gas emissions reduction of 10,000t/yr.

President and chief executive officer (CEO) Allen Hamblen said, “By adding 24 cement bulk hauler trucks and a fuelling centre at our Oro Grande cement plant, CalPortland continues to demonstrate our on-going commitment to achieving zero emissions through environmental stewardship and lowering our carbon footprint within the communities where we operate.”

CalPortland launches sustainable product line

17 June 2020

US: CalPortland has announced the launch of Advancement, a product line of cements containing sustainable materials and produced using renewable processes. These include the replacement of 15% of the Ordinary Portland Cement (OPC) clinker with blended limestone. The company currently offers Advancement Light for aesthetic design and Advancement High Sulphate for general use concrete applications and when high sulphate resistance is required, both of which have 10% lower embodied carbon than OPC. More products are planned to follow.

CalPortland president and chief executive officer (CEO) Allen Hamblen said, “Advancement is a line of products that can be combined with other concrete carbon reduction technologies to further enhance performance and increasingly reduce the embodied carbon of concrete.”

CalPortland signs FLSmidth up for Mojave raw mill project

27 May 2020

US: CalPortland has awarded a supply contract to FLSmidth for a new raw mill at its integrated Mojave plant in California. The scope of supply includes engineering, equipment and installation of a new OK 48-4 Raw Mill with a Condition Monitoring System and an ECS/ProcessExpert system. The mill is scheduled to be in operation in late 2021. No value for the current order has been disclosed.

“The new OK Raw Mill from FLSmidth will increase reliability and efficiency at our Mojave plant," said Bruce E Shafer, Senior Vice President for Cement Operations at CalPortland. It follows the purchase of a FLSmidth OK Cement Mill at the same plant in 2004. FLSmidth added that as both OK mills at the plant will share the same gearbox design, the unit will be able to streamline maintenance and manage inventory costs by sharing the one spare FLSmidth MAAG WPU-200 assembly.

CalPortland awarded equipment grant for Oro Grande cement plant

18 November 2019

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 (NOx), 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 Department of Energy recognises CalPortland in Better Plants program

01 October 2019

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.

CalPortland research study looks at CO2 absorption by concrete structures

01 July 2019

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.

CalPortland wins grant for new railcar mover

05 June 2019

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.

CalPortland officially opens new bulk cement loading unit at Oro Grande cement plant

10 May 2019

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.
