Supplementary cementitious materials (blast furnace dust - for recovery to generic market for)

The activity generating the emissions is blast furnace dust, for recovery to generic market for supplementary cementitious materials. The reference product is supplementary cementitious materials. Supplementary cementitious materials (SCMs) are materials used to substitute clinker in cement production. SCMs do not usually have an elastic demand as they are mostly produced as by-products. Examples of SCMs are: fly ash, by-product of coal-dired electricity, and blast furnace slag, by-product of iron and steel production. According to Scrivener et al. (2018) clay is the material that could supply an increased demand for SCMs. Scrivener et al. 2018. Calcined clay limestone cements (LC3). Cement and Concrete Research, 114, 49-56. https://doi.org/10.1016/j.cemconres.2017.08.017 The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity. Please refer to the ecoinvent documentation here for full details: https://ecoquery.ecoinvent.org/3.11/cutoff/dataset/22542/documentation.
