A new framework for assessing the environmental impacts of circular economy friendly soil waste-based geopolymer cements
Abstract
Portland cement is one of the principal constituents used as a building material and is responsible for high energy consumption and greenhouse gas (GHG) emissions. Any attempt to reduce cement usage would make savings in<br/>energy usage and GHG emissions. A case study of Portland cement (CEM-I) replacement using alkali activated soil filter cake as a geopolymer mortar is presented to demonstrate application of a three-stage GHG emission<br/>estimation and comparison methodology using a process-based life cycle assessment (LCA) study, with a focus on benchmarking environmental sustainability. Results indicate that the alkali activated soil filter cake reduced<br/>total GHG emissions by 31% compared with CEM-I, which equates to 110 kgCO2-eq/m3. Transportation by rail was found to be more sustainable compared with by road, with an overall higher GHG emission reduction of<br/>between 5 and 10%. For road transport, heavy goods vehicles (HGV) of between 3.5t and 5.7t recorded the highest GHG emissions whilst articulated lorries recorded the lowest GHG emissions. Furthermore, the results<br/>also demonstrated that a bulk carrier is the most environmentally sustainable option for overseas raw material transportation. Monte-Carlo simulations signified the likelihood of achieving lowered GHG emissions when<br/>considering commercial production and inventory changes across different countries varies from 18% to 71%. These results highlight the importance of critical analysis of several factors which contribute towards overall<br/>environmental sustainability, prior to decision making on sustainable materials. Further research is encouraged on developing processes and methodologies to prioritize selection of sustainable materials to optimize sustainable benefits.
