UK: Cleantech firm Carbon8 Systems has been placed into administration, with business advisory firm Quantuma appointed as administrator on 12 November 2025. Carbon8 Systems was founded in 2006 as a University of Greenwich spin-out, focused on research and experimental development within natural sciences and engineering. The company developed Accelerated Carbonation Technology (ACT), a patented process that captures CO₂ emissions and converts them into carbon-negative aggregates sold under the CircaBuild brand. The company also developed CO₂ntainer™, a modular solution which enabled on-site carbon capture and treatment of industrial residues.

Quantuma was instructed by the company’s board to provide advisory support in April 2025, as the company faced cash flow difficulties while seeking investment. Despite efforts to secure funding, this was not successful within the required timeframe. As part of the administration process, Carbon8’s operations at Medway Campus, University of Greenwich, and its premises at Wraxhalls storing plant will close. Eleven employees were made redundant shortly before the appointment on 10 November 2025.

Chris Newell, Quantuma managing director and joint administrator, said “It is always difficult to see a company with such innovative intellectual property (IP) be placed into administration. I expect there to be strong appeal in the assets and any parties interested in the acquisition of the IP are welcome to make contact with us.”

Senegal: The country’s cement sector recorded a slowdown in August 2025, according to provisional figures from the Directorate of Forecasting and Economic Studies (Dpee), cited by the National Agency for Statistics and Demography (Ansd). Cement production fell by 14% month-on-month following several months of growth, reflecting weaker domestic and external demand. The decline was driven largely by a 24% drop in local sales, linked to a slowdown in construction activity and inventory adjustments. Exports also eased, falling by 8% from July 2025.

Despite the monthly setback, the sector maintained positive momentum year-on-year. Production in August 2025 was 10% higher than in August 2024, supported by strong export growth of 44% as regional demand remained firm. Local sales posted a modest increase of 0.9% compared to August 2025.

Netherlands: Sweden-based Paebbl's demonstration plant at its Rotterdam research and development centre has reached a cumulative 500 hours of production in the eight months since it entered operation in March 2025. The plant uses captured CO₂ as a feedstock to produce carbon-storing cementitious materials. Meanwhile, Paebbl has operated its pre-existing pilot plant for a cumulative 2000 hours. The producer is now designing its first commercial-scale plant.

Malaysia: YTL Cement has received environmental product declarations (EPDs) covering products across its cement, concrete and precast ranges. An EPD is a third-party-verified document that discloses a product’s environmental impact throughout its full life cycle in line with international standards.
