US: Solidia Technologies has entered a technology licensing agreement with CalPortland. The deal grants CalPortland limited rights to use Solidia’s patents, which can reportedly reduce the carbon footprint of cement and concrete by up to 50%. The limited licenses will allow CalPortland to use the Solidia technology to develop low carbon solutions. CalPortland also purchased certain laboratory and plant assets from Solidia.
CEO of Solidia Technologies, Russell Hill, said "CalPortland's unwavering commitment to decarbonisation of the cement and concrete industries makes it a great partner for continuing the vast development and research advanced by Solidia more than a decade ago."
India: The Bhubaneswar Municipal Corporation has decided to continue its partnership with Dalmia Cement, allowing the company to receive an additional 70,000t of refuse derived fuel (RDF) from a temporary transit station at Gadakana. This decision comes as part of ongoing efforts to manage the substantial amount of RDF generated from daily waste processing, according to the New Indian Express.
An official from the civic body said "As the waste-handling site receives around 450t/day of garbage, we have agreed to allow Dalmia to take another 70,000t of waste. Previously, we had signed a contract with the company to send 70,000t of RDF to its Rajgangpur factory for co-processing within nine months. In the last six months, around 50,000t of waste has been sent."
India: The Jaipur Heritage Municipal Corporation has successfully converted around 6000kg of seized single-use plastic into a revenue-generating resource by selling it to cement plants. The plastic was collected over the past three to four months from local markets as part of an anti-plastic campaign, according to the Press Trust of India.
Commissioner Abhishek Surana said "Disposal of the seized single-use plastic was a major issue. We assessed that a supply chain exists in the system and installed refuse derived fuel machines at dumping yards to shred the plastic and sell it to cement manufacturing plants. It has also started generating revenue for the corporation."

Holcim to invest US$278m in Swiss cement plants 28 June 2024
Switzerland: Holcim plans to invest around US$278m in its three Swiss cement plants to reduce the use of fossil fuels in cement production and comply with future limits set by the Swiss Air Quality Control Ordinance. The ‘Phoenix’ project alone is expected to cost between US$78 and US$111m, according to Clemens Wögerbauer, chief commercial and sustainability officer at Holcim Central Europe West.
The Phoenix project will reduce the use of lignite for heating cement kilns. A gasifier will be constructed to process waste materials like residual wood, paper sludge and plastics into synthesis gas for heating the kilns. Additionally, a catalyst powered by the kiln's waste heat will be used to reduce nitrogen and ammonia emissions, aligning with future Swiss environmental targets. The Siggenthal plant is expected to reduce its CO₂ emissions by over 30,000t/yr from its current output of 450,000t/yr.
The new facility is scheduled to start operating in 2028 and may be replicated in other Holcim cement plants if successful. The Phoenix initiative will increase the proportion of alternative fuels used from the current 57% to 80%, targeting over 85%.
US: Holcim has invested in Travertine, utilising the startup's technology to bind CO₂ from direct air capture into advanced mineral components for permanent carbon sequestration. This investment, made through Holcim MAQER Ventures, will scale Travertine’s technology for cement decarbonisation.
Chief Sustainability Officer at Holcim, Nollaig Forrest, said, "We're excited to work with innovative startups like Travertine to advance our goal of making decarbonised cement and concrete a reality at scale this decade. Driving circularity, Travertine reduces carbon emissions by capturing and binding CO₂ into advanced mineral solutions."
Mondi and Cemex launch SolmixBag in Spain 28 June 2024
Spain: Mondi has launched the 'SolmixBag', a sustainable packaging solution, in collaboration with Cemex in the Balearic Islands of Ibiza, Mallorca and Menorca. The single-layer paper bag is designed to store and transport dry mortar, dissolving in the mixing process and integrating with the cement to reduce waste. The Balearic Islands have strict legal requirements on landfilling, waste incineration and extended producer responsibility, which have reportedly initiated the partnership.
Commercial Director at Mondi, Fabio Barbieri, said "This is an exciting step in the trajectory of SolmixBag, which offers an easy and convenient solution to use on construction sites. The product launch brings our MAP2030 goals to life by effectively reducing waste, and also illustrates our collaborative approach.”
US: Queens Carbon has secured a US$14.5m grant from the US Department of Energy under its SCALEUP program. The funding will support the pilot of Queens Carbon's low temperature, ‘zero CO₂’ emission technology at an existing cement production site. Queens Carbon's supplementary cementitious materials, which replace 20-50% of the high-CO₂ binder in cement, will be produced at a pilot plant with a capacity of 10t/day.
CEO Daniel Kopp said “This SCALEUP grant is a tremendous step forward on our path to commercialisation. Partnering with the Department of Energy and a major cement industry player to deploy, operate, and optimise our 10t/day pilot plant will put us on an accelerated path to gigatonne-scale CO₂ reductions.”
Austria: Austria's cement industry produced approximately 4.4Mt in 2023, a 15% decrease from 2023. According to Holcim Austria CEO, Berthold Kren, there will be another double-digit decline in 2024. Kren highlighted a significant downturn in construction sectors, with a notable drop in housing permits. Infrastructure construction in eastern Austria is also decreasing, aligning with broader negative economic trends affecting the industrial construction sector.
India: UltraTech Cement says that it will acquire a 23% stake in The India Cements. The Press Trust of India has reported the value of the deal as US$226m. The transaction is scheduled for completion by the end of July 2024.
