UK: UK-based startup Cocoon has raised €4.9m in pre-seed funding to develop technology that repurposes byproducts from electrified steel furnaces into a ‘near-identical replacement’ for blast furnace slag, according to the company. The modular technology integrates into existing steel-making processes without disrupting operations or requiring high capital expenditure, reports UK Tech News. Cocoon targets a 50% replacement of cement in concrete, aiming to reduce emissions for producers. Initial tests are underway at a steel plant in northern England, followed by another in the US.

Cocoon CEO Eliot Brooks said "We’re turning a byproduct with little use into a valuable product that the market badly needs and can be easily integrated into existing supply chains. By repairing a broken link in the circular economy, Cocoon provides steel makers with a new revenue stream while meeting the low-carbon material needs of the concrete industry. For every 1t of Cocoon’s slag-based cementitious material used, 1t of CO₂ can be avoided."

Brooks hopes Cocoon's climate technology will be integrated into a pilot plant by late 2025.

Uganda: West International Holding has commenced construction of a US$200m cement factory on 50 acres in Buikwe District, reports the Daily Monitor. The plant is located in Njeru municipality and construction is expected to complete by August 2025. It will employ 1800 workers and produce 4000t/day of cement.

Ambrose Byona, group director, said “This factory is going to support markets in the Central (Kampala areas), Mwanza in Tanzania and Mugingo in Kenya. We also want to use the railway to transport these products to avoid wearing out the road with loaded trucks.” The project will also provide a health centre and a school for the community.

Balaam Barugahara, state minister for gender, labour and social development, assured that local youth employment will be prioritised. However, Njeru municipality mayor Yassin Kyaze asked the company not to exploit employees like most plants in Njeru municipality are allegedly doing, saying such conduct has cast most plants negatively in the public domain.

Colombia: Cementos Argos recorded revenues of US$329m in the second quarter of 2024, down 1% from the same period in 2023. The company’s quarterly earnings before interest, taxation, depreciation and amortisation (EBITDA) was US$68.8m, while net profit reached US$31.2m. This net profit result includes the markets where it operates directly and the 31% stake it holds in Summit Materials in the US. According to the company, this result is explained "by the impact of seasonality in Summit's operations, which generate most of its net profit during the second and third quarters of the year."

Cementos Argos shipped 2.5Mt of cement across Colombia, Central America and the Caribbean in the second quarter of 2024, up 2%. However, in Colombia alone, volumes fell by 5% to 1.3Mt, despite rising exports. The company recorded a 14% rise in quarterly EBITDA to US$41.2m, with year-to-date EBITDA up by 11% to US$89.6m. In Central America and the Caribbean, Q2 2024 EBITDA was US$38m, a 13% year-on-year increase.

Cementos Argos expects improvements in Colombia's cement deliveries over the next 12 to 18 months due to stabilising new home sales, reduced mortgage rates, moderated inflation and improved housing subsidies.

South Korea: Ssangyong C&E has exported 30,000t of low-carbon limestone cement (Type IL) to the US, its first such shipment following three years of research and development, according to AJU News. The product reportedly has a reduced clinker content and maintains the same physical performance as general cement. The producer plans to export 200,000t to the US in 2024 and 600,000t in 2025.

A Ssangyong C&E official said "Currently, our country's national standards stipulate that mixed cement only uses slag, fly ash and pozzolan. In order to reduce carbon emissions in the future, conditions must be created where various types of eco-friendly cement, including limestone cement, can be used."

India: Thiruvananthapuram city Corporation has conducted a trial run of its refuse-derived fuel (RDF) plant at Sanmathi Park, Chala. The plant processes up to 1t/day of legacy waste, which is hard to segregate, to produce fuel for cement plants. The plant processes 40kg of materials per 15-minute cycle. Currently, non-recyclable materials are sent to Tamil Nadu cement plants. The government plans to establish at least one RDF plant per district as a permanent solution.
