Europe: US-based company GCP Applied Technologies has received a European patent for increasing the efficiency of cement grinding by using sustainable raw materials. The grinding aids and quality improvers allow the use of bio-derived glycerol and reduce the use and the impact of oil-derived chemicals. The new Opteva and Tavero brand cement additives enable cement producers to reduce the energy consumption and the CO₂ emissions associated with cement production, with a reduced use, or no use at all, of oil-derived chemicals.

European Patent No. EP 1 728 771 B1 has been granted and registered into 17 European countries. The patent addresses methods for increasing the efficiency of cement and mineral grinding by using sustainable raw materials.

The patent relates to methods for improving the efficiency of grinding materials such as clinker and limestone, using glycerol derived from biofuel production, in combination with various grinding additives. GCP products can help to reduce the carbon footprint of cement and concrete. Grinding aids and quality improvers make cement manufacturing more efficient, while concrete admixtures can reduce the amount of cement needed to achieve a given strength specification.

US: Charah Solutions has launched a proprietary fly ash thermal beneficiation technology that improves the quality of fly ash. It says that its new MP618Multi-Process technology reduces loss on ignition (LOI), ammonia, activated carbon and moisture in fly ash.

The technology allows for the beneficiation of both wet and dry fly ash. It advantages include lower costs, self-contained environmental controls that can be deployed in weeks, as opposed to years and a modular design that can be scaled up or down to increase production based on market demand.

MP618 can process both wet and dry fly ash. It can be installed at both operating and non-operating power plants, regardless of whether the fly ash is current production or legacy ash stored in ponds or landfills. The technology also allows for the processing of kiln dust to remove mercury for emissions regulations compliance. With the introduction of MP618, Charah Solutions expects to increase its supply of marketable fly ash to concrete producers and add greater value to its utility customers.

“MP618 will expand our MultiSource materials network, a unique distribution system of more than 30 nationwide sourcing locations, and improve our ability to provide a continuous and reliable supply of supplementary cementitious materials, including quality fly ash and slag cement, for ready mix concrete producers and other customers throughout the US,” said Scott Ziegler, Vice President of Byproduct Sales at Charah Solutions.

Greece: Titan Group has submitted a share exchange offer to help list its shares at exchanges in Brussels and Paris. Following the completion of the process, Belgium-based Titan Cement International will become Titan's ultimate parent company managed from Cyprus, according to Reuters. The group intends to list its shares at Euronext Brussels with secondary listings on the Athens Exchange and Euronext Paris. Titan says it wants to broaden its funding sources by improving access to international finance.

Germany: HeidelbergCement has warned that its result from current operations before depreciation will be lower than expected so far in 2018 due to poor weather in the US and rising energy costs. It maintained that its sales volumes and revenue for the first nine months of 2018 would be ‘within expectations.’ The building materials company also reassured investors that its group share of profit for 2018 would also be as expected. It will release its results for the third quarter of 2018 on 8 November 2018.

India: ACC’s net sales rose by 13% year-on-year to US$1.45bn for the first nine months of 2018 from US$1.3bn in the same period in 2017. Its sales volumes of cement grew by 8% to 20.9Mt from 19.3Mt. Its operating earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 6% to US$212m from US$200m and net profit after tax rose by 10% to US$107m from US$98m. The cement producer attributed its performance to growing cement sales that were able to offset rising input costs including coal, petcoke, diesel and slag.
