Carbon8 Systems to deploy its pioneering technology at Vicat Group cement company in France

  • First commercial deployment of Carbon8 System’s CO₂ntainer
  • Its Accelerated Carbonisation Technology captures CO₂ emissions to convert cement bypass dust to usable aggregate product
  • Global cement industry responsible for 5%-7% of global greenhouse gases
  • Vicat commit to reduce its CO2 emissions by 2030 and has a vision of carbon neutrality by 2050

(London): Carbon8 Systems, the UK company that invented and owns a process that combines industrial waste residues or by-products with captured CO₂ emissions to produce high-value, lightweight construction aggregates, has signed a commercial agreement with the Vicat Group cement company.

Carbon8 Systems will deploy its award-winning technology at Vicat’s Montalieu cement plant in southern France next month.

It is Carbon8 Systems’ first commercial deployment of its CO₂ntainer system (a modular, containerised solution) in Europe and follows successful demonstration projects at cement plants in the UK and Canada.

The CO₂ntainer will be deployed directly onsite at Montalieu and integrated into Vicat’s existing industrial processes. Crucially, it will capture CO₂ directly from the plant’s flue gas emissions, which will be used to convert cement bypass dust into lightweight aggregates through the use of Carbon8 Systems’ patented Accelerated Carbonisation Technology (ACT) solution (see Notes to Editors).

In its first phase of operation, Carbon8 Systems’ CO₂ntainer will process and convert up to 12,000 tonnes of cement bypass dust into valuable construction aggregates. Vicat can commercially repurpose the aggregates in various applications, for instance in lightweight concrete blocks.

Dr Paula Carey, co-founder and Technical Director of Carbon8 Systems, said: “Securing a commercial agreement with Vicat, a family-run cement company that has been in business for more than 150 years and with a strong commitment to process innovation and sustainability, is a massive endorsement of our technology and the R&D work that we have carried out over recent years.”

“We are delighted that Vicat has chosen Carbon8 Systems to help reduce its carbon emissions and, at the same time, create a potential new income stream for their business.”

Dr Laury Barnes-Davin, Scientific Director of Vicat said: “As part of our commitment to limit our environmental impact, Vicat has looked at a number of innovative ideas to reduce its carbon emissions. We are attracted by Carbon8 Systems’ two-part technology proposition: capturing the CO₂ that Montalieu emits and using it to produce an aggregate that can be marketed to industry. We are excited by its potential for our operations elsewhere in France and around the world.”

With the cement industry responsible for 5% to 7% of the world’s greenhouse gas emissions, Carbon8 Systems is in advanced discussions with other cement companies around the world to deploy its CO₂ntainer solution.

In addition, the company is pursuing opportunities in other sectors where waste residue disposal is increasingly expensive and CO₂ emissions need to be reduced as part of the transition to Net Zero by 2050. By utilising the waste at source and onsite, companies using ACT will reduce the amount of waste going to landfill, so further reducing the environmental impact of their operations.

Dr Paula Carey added: “Carbon8 Systems is a true circular economy company and the “only game in town” for successful and sustainable decarbonisation of industrial residues.”

In addition to cement, other sectors where ACT can be used include power generation (Energy from Waste), the steel industry, and the paper industry.

Notes to Editors:

  1. ACT relies on a process of carbonation. This process is something which happens naturally in the atmospheric conditions. If left in the open, compounds such as calcium or magnesium oxides, hydroxides, or silicates will react with the carbon dioxide. However, this process is extremely slow and can take over a year to solidify. C8S’s technology accelerates this process in a controlled way; and in doing so has created the world’s only economically-viable form of carbonisation and carbon capture utilisation. C8S’ expertise around the carbonation process means that it is able to control the physical characteristics of the output end-product.

    The ACT process mineralises and stabilises these industrial by-products or residues to produce a granular solid. The end-product has various valuable applications, such as aggregates for construction, agricultural fertiliser, or other high-value applications. For maximum efficacy, the most reactive residues need to be high in calcium or magnesium oxide, hydroxide, or silicates.

  2. Dr Paula Carey has been working on the development of accelerated carbonation for more than 20 years. With Dr Colin Hills, the inventor of ACT, she co-founded the business in 2006 when it spun-out of the University of Greenwich in London. Today, Dr Colin Hills is the company’s R&D Director, Executive Chair of the company is John Pilkington who holds a number of non-executive director roles and was a director for 20 years of Ove Arup & Partners. In 2017, the company was awarded the Queens Award for Enterprise – Innovation, and its work has received support from Innovate UK.

  3. The Vicat Group ( has over 9,000 employees working in three core divisions, Cement, Concrete & Aggregates and Other Products & Services, which generated consolidated sales of €2.740 billion in 2019. The Group operates in twelve countries: France, Switzerland, Italy, the United States, Turkey, Egypt, Senegal, Mali, Mauritania, Kazakhstan, India and Brazil. Some 64% of its sales are generated outside France. The Vicat Group is the heir to an industrial tradition dating back to 1817, when Louis Vicat invented artificial cement. Founded in 1853, the Vicat Group now operates three core lines of business: Cement, Ready-Mixed Concrete and Aggregates, as well as related activities.
