Low-Cost Electrochemical Approaches to Deep-Decarbonization
… load-following electricity, and steel, iron, and cement production together account for 27% of emissions and are considered hard-to-decarbonize sectors. We demonstrate and analyze several approaches using electrochemistry in an attempt to address two of these hard-to-decarbonize sectors: cement …

Determination of metal concentrations in vegetation, soil, dust, and water in the vicinity of a cement factory in North West province, South Africa
On a per capita basis, cement is the second most widely consumed product in the world and its demand is increasing globally due to population growth and urbanisation. Manufacturing plants produce cement kiln dust (CKD) as one of the by-products while coal provides the dominant energy source in the …

Resource efficiency decision-making tools for industry: a new environmental performance metric for clinker manufacturing
… representing 70% of those emissions: steel, cement and chemicals. Cement is a particularly challenging sector to decarbonise, since the decomposition of limestone during clinker manufacturing releases CO<sub>2</sub>, and as a result, complete decarbonisation of the process is impossible. …
