Into the future

19 July 2018, Published under Cement News

There is no way we can imagine the world without cement and concrete. From 30 years ago, when International Cement Review was first published, until today, cement production on the planet has quadrupled. Depending on regional developments this volume may more or less stabilise going forward or even exhibit further growth. In any case, the cement industry will continue to lower the CO 2 footprint of cement and concrete. By Dr Martin Schneider, VDZ, Germany. Figure 1: cements containin...

Turkey seeks alternatives

23 February 2018, Published under Cement News

The concept of a circular economy is growing in influence and as a result the cement production process has begun to evolve. As a large-scale cement producer, Turkey shows considerable potential for the adoption of this alternative economy.  Figure 1: the circular economy cycle Turkey has begun to adopt the concept of a circular economy, a waste-to-energy solution that is a high priority for European Union. The circular economy model is based on the principle that natural resour...

Cembureau highlights role of cement industry in EU plastic waste disposal

17 January 2018, Published under Cement News

Following the European Commission's initiative to develop a dedicated plastics strategy in a circular economy, published on 16 January, the European cement association, Cembureau, has highlighted the part played by the cement industry in reducing plastic waste. Apart from the importance of the need for a ban on landfill of recoverable and recyclable waste, the organisation urges policymakers to strongly focus on the recognition that cement plants can treat different waste streams such as ...

Vicat enters EUR1.3m ARM venture with Serpol

11 January 2018, Published under Cement News

Vicat and Serpol have entered a EUR1.3m joint venture, Terenvie, to treat oil-polluted soil and turn it to cleaned, mineral-rich land. This source of silica or clay can then be used as “a partial replacement (five per cent) of quarry materials, to save natural resources without impacting the quality of the cement, perfectly standardised,” said Stéphane Rutkowski, manager at Vicat. Earthworks produce around 5Mta of oil-polluted soil at the sites of former service stations, oil depots or ac...
