India: The municipal corporation of Kolkata, West Bengal, has enacted regulations requiring landowners to send construction waste from projects on their property to construction and demolition waste recycling facilities. The Telegraph newspaper has reported that the new regulations apply to all construction, demolition and repairs work on plots of land larger than 0.24 hectares. The city authorities have built a 183,000t/yr recycling plant in New Town, Greater Kolkata, to support the increased volumes.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

France: Hoffmann Green Cement Technologies has commissioned its H2 plant, a 1000t/day clinker-free cement plant, adjacent to its existing H1 clinker-free cement plant in Bournezeau, Pays de la Loire. L'Usine Nouvelle News has reported that the new plant took 24 months to build and cost Euro22m. The main part of the plant consists of a 70m tower, where activated clay, ground granulated blast furnace slag (GGBFS) and gypsum are mixed to produce the cement. It is installed with solar panels capable of supplying 50% of its energy consumption. The producer says that its clinker-free cement has over 90% lower CO₂ emissions than cement produced with ordinary Portland cement (OPC). It aims to sell 24,000t of the product throughout 2023.

Uzbekistan: United Cement Group subsidiary Qizilqumsement says that it has awarded contracts for the upgrade of Lines 1 and 2 at its Qizilqum cement plant in Navoiy Region. Uzbekistan Newsline has reported that the producer has completed testing to ascertain the lines' parameters of operation, fuel and energy consumption and output. This will inform its decisions, with a view to reducing the cost of clinker production.

Qizilqumsement is currently in the process of building the Qizilqum plant's new 767,000t/yr Line 4, which will also increase its clinker capacity by 657,000t/yr. The producer expects this to lower the cost of its clinker production by 30%.
