“…Also 0.0784 kg oil eq of Fossil resources scarcity is expected for every 1 kg of OPC produced. This resonates with the value from the study of [48,53] with values ranging from 0.07 to 0.234 kg oil eq. ; the three impacts categories with high environmental impacts are human health, terrestrial ecotoxicity and Fossil resources scarcity.…”

“…The result of the endpoint analysis is comparable with results of literature with CO2 emission and the clinker production stage being the highest contributors [52,53]. There is variation in the resources of Chen et al and Tun et al, this is because coal was the major source of fossil fuel for the production of cement.…”

“…Pandemic in the aquatic community is often time traced to toxicity. Water consumption during the production of cement is 0.00185 m3: it was found to be comparable with that of Tun et al and Chen et al which was within 0.00019-0.00187 m3 [52,53]. Also 0.0784 kg oil eq of Fossil resources scarcity is expected for every 1 kg of OPC produced.…”

The concern for environmental related impacts of the cement industry is fast growing in recent times. The industry is challenged with high environmental impact which spans through the entire production process. Life cycle assessment (LCA) evaluates the environmental impact of product or process throughout the cycle of production. This can be done using either or both midpoint (process-oriented) and endpoint (damage-oriented) approaches of life cycle impact assessment (LCIA). This study assessed the environmental impact of 1 kg Ordinary Portland Cement (OPC) using both approaches of LCIA. This analysis was carried out using a data modeled after the rest of the world other than China, India, Europe, US and Switzerland. The dataset was taken from Ecoinvent database incorporated in the SimaPro 9.0.49 software. The result of the analysis showed that clinker production phase produced the highest impact and CO2 is the highest pollutant emitter at both endpoint and midpoint approaches. This is responsible for global warming known to affect both human health and the ecosystem. Also, toxicity in form of emission of high copper affects the ecosystem as well as humans. In addition, high fossil resources (crude oil) are consumed and pose the possibility for scarcity.

“…According to [21], different parameters describe the environmental performances of a product, such as environmental impacts, resource use, waste categories, and output flows [23][24][25][26][27]. In the literature, several studies assessed the impacts of cement production considering its upstream processes (i.e., production of commodities, raw materials, transport to the factory plant, production process) [28].…”

The attention to environmental impacts of cement production has grown fast in recent decades. The cement industry is a significant greenhouse gases emitter mainly due to the calcinations of raw materials and the combustions of fuels. This paper investigates on the environmental performances of cement production and on the identification of factors driving emissions. For this purpose, a sample of 193 different recipes of gray cement produced in Italy from 2014 to 2019 according to the European standard EN 197-1. This paper identifies the consumption impact categories (e.g., fossil fuels, renewable and non-renewable secondary fuels) that explain the assessment of the Global Warming Potential, one of the most crucial impacts of cement production. Having regard to the overall examined dataset and each cement type, a set of predictive models is implemented and evaluated. A similar approach has been adopted to produce accurate predictive models for further environmental impact categories that quantify emissions to air. The obtained results provide important information that can support cement producers to develop low-impacting cement recipes.
