Switzerland: Holcim has partnered with Bloomberg Media to launch the Circular Cities Barometer, an exploration of best circular economy practices from cities around the world. The platform aims to improve understandings of how to empower cities to become more circular. The partners will publish the Circular Cities Barometer’s first findings at the Bloomberg Green Summit in April 2022.

CEO Jan Jenisch said “Circularity is the opportunity of our time. It unlocks economic growth in a way that is climate-friendly, nature-positive and socially inclusive. My vision for construction is to build more new from the old with recycled materials in every new building.”

Costa Rica: Société Générale de Surveillance has awarded Holcim Costa Rica its Positive Packaging certificate for 100% packaging energy recovery in 2021. The company offset the 1500t carbon footprint of its packaging production for the year by sorting and co-processing 14,000t of paper as fuel. It sourced the paper from its customer cement bag return scheme and through municipal recycling services run by fellow Holcim subsidiary Geocycle Costa Rica.

Holcim Costa Rica sustainability coordinator Catalina Mora said “Waste management is a global challenge, so this project has a direct impact on our contribution as a company to the vision of sustainability for the country.”

India: First Construction Council and the Indian Cement Review have named Dalmia Cement Bharat managing director and chief executive officer (CEO) Mahendra Singhi as Person of the Year at the Cement Expo on Cementing India’s Future for the 2022 financial year. Singhi won the title for his exemplary contribution towards transformational changes in the Indian and global cement sectors, significantly facilitating the transition to a more circular economy. Singhi is the previous president of the Indian Cement Manufacturers Association (CMA) and the previous chair of the National Council for Cement and Building Materials (NCCBM). He has achieved recognition as a Conference of the Parties (COP) 26 Business Leader and a World Bank Group Carbon Pricing Champion.

Singhi said “I am honoured to receive this award on behalf of people with whom I worked in the last 43 years in various companies who have shaped my clean and sustainable journey and I dedicate this award to them. I feel fortunate that I have been able to have visionary mentors and committed colleagues who could support my cemented journey.” He added “I am hopeful about the future as we transition towards newer business models that will drive us to remain profitable, ensure value creation and, at the same time, achieve environmental sustainability.”

UK: Innovative Ash Solutions has received a Euro588m Scottish government grant to establish a 20,000t/yr ash processing plant in South Lanarkshire. The Herald newpaper has reported that the plant will process boiler ash, cyclone ash and incineration fly ash for use in local cement production. When commissioned in 2022, the plant will eliminate 6104t/yr of CO₂ emissions, according to the operator. The government granted the funding under its Zero Waste Scotland circular economic investment scheme.

The company said “Using this new patented process, which diverts waste materials from landfill and avoids the use of virgin sand, creates a product which is cheaper and will reduce the environmental impact of cement production compared to the use of imported pulverised fuel ash.”

Innovative Ash Solutions is a joint venture of waste management company Levenseat and consultancy Organic Innovative Solutions.

India: The Federation of Indian Chambers of Commerce and Industry (FICCI) has awarded UltraTech Cement its Indian Circular Economy Award 2021 in the large enterprise category. The federation said that the award recognises UltraTech Cement's efforts to accelerate the development of a circular economic business model and celebrates its new impactful and innovative practices in 2021.

US: Charah Solutions has signed a contract with Associated Electric Cooperative (AECI) to receive bottom ash, fly ash and boiler slag from its Thomas Hill Energy Center coal-fired power plant in Missouri until 2026. Charah Solutions will recycle the by-products to produce supplementary cementitious products and redistribute these through its MultiSource materials network. The network consists of 40 locations across the US.

President and CEO Scott Sewell said "We are delighted to partner with AECI to manage their ash marketing needs at Thomas Hill while supplying our concrete producers with the high-quality material they need."

Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO₂. EuropaPress has reported that the use of CO₂ would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO₂ from the concrete’s production.

Australia: A paper published in the journal Resources, Conservation and Recycling has reported that concrete made with treated slag is 8% stronger than standard slag concrete and 17% stronger than concrete made with conventional aggregates. A Royal Melbourne Institute of Technology (RMIT) team produced treated slag concrete using slag that had absorbed phosphate, magnesium, iron, calcium, silica and aluminium during use in wastewater treatment. Researcher Biplob Pramanik said, “The things that we want to remove from water are actually beneficial to concrete.” Pramanik said that the findings have promising implications for the water and concrete sectors within the circular economy.
