Kyrgyzstan: Kant Cement has begun excavating the Severnaya Gryada limestone deposit near to its Kant cement plant. The producer says that the limestone has a higher purity than that from its existing Agalatas mine. It therefore expects the Kant plant to reduce its raw materials consumption and eliminate a part of its dust emissions. Kant Cement currently replaces a part of the limestone in the plant’s cement production with 65,000t/yr of fly ash.

UK: Aggregate Industries and Coomtech have partnered to develop low-energy kinetic drying technology for pulverised fuel ash (PFA) from power plant. The partnership will see Aggregate Industries use Coomtech’s kinetic dryers in its PFA processing, as part of its effort towards increasing the volume of waste materials incorporated in its products to 3Mt/yr from 1.5Mt/yr by 2025. The project has attracted funding from the UK government Department of Business, Energy and Industrial Strategy (BEIS).

Chief commercial officer Chris Every said “We’re delighted to have the support of Aggregate Industries in this grant project. Coomtech is especially pleased to have the business’ ongoing technical and commercial input to the project operation and analysis of performance. In addition, the opportunity to work together with a brand that is leading the way in creating new materials that will prove fundamental to the future of the construction sector and meet net zero objectives.” Every continued “The added benefit of our new drying technology is its flexibility - providing the potential to dry a wide range of materials being considered to aid the greening of the cement industry, including limestone, ground blast furnace slag (GBFS), natural pozzolans and other crushed and milled minerals that can offer an activated character to combine in cement and concrete mixes.”

Germany: Cemex Deutschland has acquired a 53% majority stake in Saxony-based stone mining company ProStein. ProStein’s six quarries yielded 3Mt of raw materials in 2021. Cemex Deutschland says that the acquisition doubles its own raw materials capacity.

Saudi Arabia: Arabian Cement says that the Jeddah Commercial Court has ruled in its favour in a lawsuit it filed against Emaar, the Economic City Company, to claim outstanding quantities of limestone it was due in an agreement the companies signed in 2012.

However, Arabian Cement maintains that it did not receive 5.3Mt of the total.

Arabian Cement previously gave land to Emaar in return for a limestone supply deal. Emmar company has been developing the King Abdullah Economic City.

India: The Tamil Nadu Federation of Panchayat Presidents, an overarching organisation for local government leaders, has begun a protest against unlawful cement plant practices in the state. The New Indian Express newspaper has reported that the federation’s president Sellam Kadamban said that limestone mines and trucks are operating illegally, creating pollution and traffic collisions.

Zimbabwe: Livetouch Investments plans to invest US$100m in the construction of an integrated cement plant. The Herald Zimbabwe newspaper has reported that the group plans to establish the new facility in phases, with the first phase costing US$15 – 20m. The phase will include the exploration of possible locations for the plant with suitable limestone resources, which could then also supply its Redcliff grinding plant. The grinding plant currently imports 4000t/yr of Zambian clinker and also buys raw materials from Lafarge Zimbabwe.

Managing director Kyle Wang said “We are still limited by the limestone resources in the country.” He said that the company has identified ‘good limestone deposits’ in Rushinga, Nyamapanda, Bulawayo and Masvingo, however “The problem with some of the limestone is the quality.”
