The company offset the 1500t carbon footprint of its packaging production for the year by sorting and co-processing 14,000t of paper as fuel. It sourced the paper from its customer cement bag return scheme and through municipal recycling services run by fellow Holcim subsidiary Geocycle Costa Rica.

Holcim Costa Rica sustainability coordinator Catalina Mora said “Waste management is a global challenge, so this project has a direct impact on our contribution as a company to the vision of sustainability for the country.”

Australia: Boral says that its emissions reduction targets have been approved by the Science Based Targets Initiative (SBTi) as being consistent with the levels required to meet the goals of the Paris Agreement. Boral released its targets in August 2021 when it said it intends to reach net-zero emissions by no later than 2050. It subsequently joined the SBTi’s Business Ambition for 1.5°C and the United Nations Framework Convention on Climate Change Race to Zero campaign.

The Australia-based building materials company plans to reduce its Scope One and Two emissions by 46% by 2030. It also plans to decrease its relevant Scope Three emissions per tonne of cementitious materials by 22%. It intends to do this by: transitioning to 100% renewable electricity by 2025 and increasing alternative fuels usage at its Berrima plant kiln; growing the proportion of revenue from its lower carbon concrete product range and optimising the efficiency of its cement plant; reducing transport emissions in its own and contractor fleet; prioritising lower carbon intensity suppliers; and exploring and testing emerging carbon capture use and storage technologies.

Boral’s Chief Finance and Strategy Officer, Tino La Spina, said “Boral is determined to become a leading innovator in sustainability through decarbonisation of cement and concrete and increasing our contribution to a more circular economy” He added “We continue to support our customers in their transition to net zero, broadening our range of high performing lower carbon concrete products to cater for all building and infrastructure applications, and offering Climate Active−certified net carbon neutral concrete.”

Honduras: Cementos Argos plans to expand the production capacity of its 1Mt/yr Piedras Azules cement plant by 35%. The plan is part of a group of planned projects, including solar power and alternative fuels, with a total investment value of US$23m. The company expects to complete all of the work before 2024. It says that the expanded operations will generate 500 new direct job opportunities.

The company will increase its energy supply from the Comayagua solar power plant to 25% of the plant’s requirements from 20% at present. It will also establish a new 1.2MW solar power plant at Río Blanquito. The cement producer will also strengthen its industrial waste co-processing operations with the aim of achieving 12% refuse-derived fuel (RDF) substitution rate by 2030, the equivalent of 5500t/yr. If reached, this will reduce the company’s carbon footprint in the country by 14%.

Chief executive officer (CEO) Luis Eduardo Tovar said "This investment is a vote of confidence of Argos in Honduras and represents our commitment to the country's economic reactivation and our firm determination to contribute to the consolidation of prosperous and sustainable communities based on competitive and visionary initiatives.” He continued “We will continue our efforts to promote the development of Honduran families through the creation of social value at a national level."

Thailand: Siam Cement Group (SCG) plans to spend US$2bn towards meeting its CO₂ reduction target by 2030. The industrial group and cement producer intends to reduce its emissions by 20% by the end of the decade, according to the Bangkok Post newspaper. Chief executive officer Roongrote Rangsiyopash, said that the investment will be made from 2022 to 2030 and that it follows the United Nation’s Sustainable Development Goals (SDG), the Thai government's bio, circular and green (BCG) economic model and environmental, social and governance standards (ESG). After 2030 the group has a net zero goal for 2050.

In cement production the SCG wants to increase its rate of alternative fuels such as biomass and refuse-derived fuel. It also wants to invest in carbon capture utilisation and storage, use electric vehicles and use artificial intelligence systems in energy management. The group plans to reduce coal usage at its cement plants in Thailand, Vietnam, Laos, Cambodia and Indonesia by 50% in 2022. It also plans to use more electricity generated by renewable energy for its factories.

US: The Portland Cement Association (PCA) has announced the winners of its Energy and Environment Awards 2021. The awards recognise cement plants’ outstanding environmental and social efforts beyond what is required.

CalPortland’s Mojave plant in California won the Energy Efficiency award for an efficiency-increasing upgrade to its vertical roller mill, which included the introduction of a bottom hopper cone on each of its cyclones and a replacement of its mill fan housing. Argos USA’s Calera plant in Alabama won the Land Stewardship award for its conversion an 8.5ha lime kiln dust stockpile into grassland. The area now forms a vibrant ecosystem including wetland habitats. The producer also installed ponds with the additional purpose of stormwater management. Titan America’s Pennsuco plant in Florida won the Overall Environmental Excellence award for its conversion of the plant’s kiln to natural gas from coal use. The upgrade has also enabled the plant to begin to substitute alternative fuel (AF) in the kiln. The Pennsuco plant plans to produce 100% Portland limestone cement (PLC) by ‘as early as 2023.’

Other awards went to Roanoke Cement’s Troutville, Virginia, plant in the Environmental Performance category and to Cemex USA’s Victorville, California, plant in the Outreach category.

PCA President and CEO Michael Ireland said “The US’s cement manufacturers continue to focus on researching and developing new and innovative ways to reduce their environmental footprint. These accomplishments and industry commitment to carbon neutrality across the entire value chain demonstrate PCA members’ dedication to energy efficiency and a more sustainable future.”

France: Germany-based ThyssenKrupp has won a contract for the installation of a new 4000t/day clinker line at Ciments Calcia’s Airvault cement plant in Poitou-Charentes. The supplier expects the new line to double the plant’s clinker capacity while also reducing its CO2 emissions. It is intended to replace the two existing lines at the site.

ThyssenKrupp will supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 type vertical roller mill and a 10,000t tangential blending silo to process raw materials for the line. A single-string, five-stage Dopol type cyclone preheater with integral calciner will be supplied that is suitable to use with alternative fuels, with the possibility of conversion to oxyfuel in future. ThyssenKrupp plans to preassemble the preheater, reducing anticipated construction time ‘by several months.’ The plant also includes a Polytrack clinker cooler, a solid recovered fuel (SRF) preparation line and dedusting systems. Commissioning is scheduled for mid-2024.

No value for the project has been disclosed by Ciments Calcia or ThyssenKrupp. However, Ciments Calcia previously announced a proposed investment of Euro300m in January 2021.
