Cyprus: Vassiliko Cement has secured environmental clearance to build a new alternative fuel (AF) store at its Vassiliko cement plant in Nicosia. Philenews has reported that the facility will replace the site’s former AF store, which burned down in a fire started by a mobile shredder in June 2022.

World: The United Nations (UN) has reviewed the progress of initiatives towards the reduction of mercury emissions from cement and other industries under its Environment Programme (UNEP). Mercury is sometimes present in the raw materials and fuel used in cement production. The sector currently emits 2220t/yr of mercury, 11% of global anthropogenic mercury emissions. The UNEP’s Cement Partnership Area aims to ensure ‘globally significant’ emissions reductions. Its priority actions include: establishing sectoral mercury inventories and baseline scenarios, encouraging techniques for the minimisation of mercury releases, increasing awareness in the industry, governments and regulatory bodies and supporting the development of policies in line with the Minamata Convention on Mercury.

The Cement Partnership Area said that it has achieved progress in expanding its cement plant mercury emissions management knowledge base and in reducing emissions. It called on governments to increase funding for projects, the development of new technologies and the publication of guidance documents.

India: JK Cement has secured regulatory approval to merge its subsidiary Jaykaycem (Central) into itself. The Free Press Journal newspaper has reported that the Allahabad bench of the National Company Law Tribunal granted the approval on 6 March 2023.

US: SLB has launched EcoShield, a geopolymer-based well cement product. The company, also known as Schlumberger, says that the product cuts out up to 85% of embodied CO₂ emissions compared with conventional well cementing systems because it does not use ordinary Portland cement (OPC). It also reduces transport related emissions by using locally-sourced natural materials and industrial waste streams in its composition. The company says that the cement-free system can be deployed throughout various phases of the well life cycle, including abandonment. It can also be deployed across a range of field applications, including corrosive environments.

Jesus Lamas, SLB’s president of Well Construction, said “Decarbonising the well construction process while ensuring safety and performance standards is critical to our industry’s pathway to net zero.” He added “The cement-free EcoShield system is a breakthrough that delivers industry-standard zonal isolation capabilities while significantly minimising impacts from upstream oil and gas production.”

EcoShield has been tested by Pioneer Natural Resources in the Permian Basin on an 18-well field testing campaign and its use is ongoing.
