Dr Paula Carey, Co-Founder & Chief Scientific Officer, Carbon8 explains the impact of carbon capture technology at Carbon8 on the productivity, efficiency and circular economy of cement plants.

Tell us about your carbon capture technology.
Carbon8’s carbon capture utilisation and storage (CCUS) technology is known as Accelerated Carbonation (ACT). In the process, carbon dioxide derived directly from flue gas generated by a cement plant is reacted with calcium minerals within the cement by-pass or kiln dust produced by the same plant without the need for purification.

The reaction occurs at atmospheric temperatures and pressures over 20-30 minutes and can be engineered so that a carbon negative lightweight aggregate is produced, through granulation of the fine grained dusts.

The technology is delivered in a containerised plant (known as the CO2ntainer) with a small footprint that is plugged directly into the flue stack of the cement plant without affecting the cement manufacturing process.

What role can your technology play when implemented in a carbon intensive industry like the cement industry?
The amount of carbon dioxide that is captured is limited by the amount of residue available, but the economics of our system means that a profit can be made for every tonne of CO2 captured without the need for subsidies, or large energy penalties or the use of expensive toxic chemicals such as amines. The process results in the sustainable management of an industrial residue that might otherwise be destined for landfill and produces a low carbon product for the construction industry reducing the need for the extraction of natural aggregate.

What is the impact of your technology on the productivity and cost of cement manufacturing?
The installation of our technology has no effect on the productivity of the cement plant, it has a low energy requirement and its installation adds to the bottom line of the cement production.

How does your technology impact the energy efficiency of a cement plant?
Because our technology operates at atmospheric temperatures and pressures, it has a low energy demand and does not have an impact on the efficiency of the cement plant.

How does your tech support the circular economy?
Carbon8’s technology produces a carbon negative, lightweight aggregate from an industrial residue, breaking the route to landfill disposal and producing a sustainable product for the construction industry that replaces the need for the extraction of natural virgin aggregate. On our website – www.carbon8.co.uk – we describe ourselves as a “circular impact company

What are the major challenges in implementation and execution of your technology?
Because the amount of CO2 captured is relatively small compared with large-scale, expensive carbon capture projects, it has been more challenging to demonstrate the economic and environmental benefits of deploying and operating our technology within the global cement industry. A Vicat cement plant in France has been using our CO2tainer since 2020, after successful trials with CRH in Canada and Hanson (now part of Heidelberg Cement Group) in the UK.

The variability of the waste streams that are available to Carbon8 also raises a challenge; every cement works is slightly different and demands a unique solution in terms of mix design for our process.

What innovations can the world expect from Carbon8 in the near future?
We are using AI to develop our process control to overcome the variability of the residues that are generated by the different hard-to-abate industries, and so facilitate the deployment of ACT solutions into other sectors, like Energy From Waste, biomass and steel.

Hard Worker Wins Three Honours at Kyoorius Design Awards

The Ramco Cements Limited’s construction chemicals brand, Hard Worker, has won three honours at the Kyoorius Design Awards 2026, including the Grand Prix – Grey Elephant in the Design in Action category.

The brand also secured two Blue Elephant honours, one for Design in Action and another for Packaging, recognising the design approach behind its brand identity and packaging.

Launched in 2025, Hard Worker entered the construction chemicals segment with the brand promise, “Hard-working products for hardworking people.” Its visual identity uses animals and birds to represent product benefits. The camel represents the water-retention capability of Hard Worker Eco Plaster, while the cheetah represents the speed and performance of Hard Worker Block Fix.

The visual language has been extended across packaging, retail, communication, literature, digital platforms and other brand touchpoints. Hard Worker uses bold colours, distinctive animal illustrations and simple visual storytelling to communicate product benefits across markets and audiences, including construction workers and applicators.

“For Hard Worker, design was never an afterthought. It was fundamental to how we wanted to build the brand. In a category that is largely functional, we wanted to create a brand that people could recognise, understand and remember instantly. The Kyoorius recognition is a wonderful validation of this design-led approach,” said Mr. AV Dharmakrishnan, CEO, The Ramco Cements Limited.

Mr. Balaji K. Moorthy, Executive Director – Marketing, Ramco Cements said “In a category where communication has traditionally been product-led and functional, we wanted Hard Worker to stand apart by making design an integral part of the brand experience. From the distinctive animal-led packaging to our communication across consumer and trade touchpoints, every element was designed to make the brand more memorable and the product benefits easier to understand.”

Within its first 12 months, Hard Worker crossed Rs 3.5 bn in sales. The latest recognition follows six honours secured by the brand’s campaign at the Kyoorius Creative Awards earlier in 2026, including the Grey Elephant Grand Prix for its Eco Plaster film.

The Kyoorius Design Awards recognise outstanding design work in India’s visual communications sector across multiple categories and platforms. The 2026 awards were announced on 12 September in Goa.

The Ramco Cements Limited is part of the Ramco Group and operates across cement and allied building-material solutions. Hard Worker is its construction chemicals brand, offering solutions across key construction applications.

Cement Firms to Invest Rs. 130 bn in Green Energy by FY28

Cement companies plan to expand clean energy capacity to 6 GW by FY28

India’s major cement companies are set to raise their clean energy capacity to 6 GW by March 2028 from around 4 GW at the end of March 2026, according to ratings agency ICRA. The planned expansion is expected to involve investments of Rs. 130 bn over the next two years.

The additional capacity could generate annual savings of Rs. 62 bn to Rs. 67 bn, resulting in an estimated payback period of 1.8 to 2.2 years. Cement is an emission-intensive industry, and leading producers have established net-zero roadmaps covering the next 15 to 20 years.

The calcination process accounts for 57 to 60 per cent of the sector’s total emissions, while fuel combustion contributes 27 to 30 per cent and electricity consumption accounts for 10 to 13 per cent. ICRA said the figures highlighted the need for a broad decarbonisation strategy involving green power, blended cement, alternative fuels and improvements in clinker efficiency.

Green energy is considered one of the most commercially attractive decarbonisation options because it can reduce emissions while lowering operating costs. Every 5 per cent increase in green power replacement can reduce power and fuel costs by Rs. 15 to Rs. 16 per tonne. A 25 per cent replacement level could therefore save Rs. 75 to Rs. 80 per tonne and expand operating margins by 140 to 160 basis points.

Cement producers are also assessing carbon capture, utilisation and storage, although high implementation costs, energy requirements and limited transport and storage infrastructure are expected to slow commercial adoption. The government has proposed Rs. 200 bn over five years to support deployment across key sectors. Meanwhile, companies are targeting thermal substitution rates of 10 to 15 per cent over the next three to five years, compared with the current industry level of around 6 per cent.
