ACCSESS for CCS projects

13 September 2022, Published under Cement News

Carbon capture, utilisation and storage (CCUS) is an important pillar of HeidelbergCement’s carbon neutrality roadmap. As part of Project ACCSESS, the company will be the first to pilot CCUS technology in eastern Europe by demonstrating post-combustion capture technology at its Górażdże cement plant in Poland. With three main focal points, the intiative aims to connect European carbon capture projects with CO 2 transport and storage under the Northern Lights initiative. By HeidelbergCement,...

Aggregates go carbon negative

06 September 2022, Published under Cement News

There is a consensus that, to reach net zero by 2050, the cement industry must embrace carbon capture, utilisation and storage (CCUS). This article looks at the potential of CCUS for the treatment of cement residues and the production of lightweight, carbon-negative aggregate, showcasing Carbon8 as a successful example of a scaling start-up.  By Dr Paula Carey, Carbon8, UK. Figure 1: aggregate product CircaBuild There are an increasing number of projects involving the capture of...

Addressing AF myths

30 August 2022, Published under Cement News

Existing misconceptions about the use of alternative fuels (AFs) continue to form a barrier to increased thermal substitution rates in cement plants. Specialist AF producer N+P addresses these myths and provides process engineering support to help cement producers increase fuel substitution rates. By N+P Group, UK. This year marks 30 years since N+P started trading alternative fuels (AFs) and alternative raw materials. The initial idea regarding the N+P venture germinated in the mind...

LC3 in codes and standards

11 July 2022, Published under Cement News

Reducing the carbon footprint of the concrete industry is a priority in the face of global warming. Limestone calcined clay cements (LC 3 ) provide one of the best options to reduce CO 2 emissions. For optimal implementation, but also to facilitate other low CO 2 solutions, standards that regulate the cement and concrete sector need be adapted quickly. In this article, two main standardisation regions are reviewed in light of the feasibility of adoption and deployment of LC 3 technology. ...
