Cement Production

The adverse consequences of producing ordinary Portland cement (OPC) on the environment have introduced cement production as the fourth largest source of anthropogenic carbon emissions after petroleum, coal, and natural gas. Managing and reducing the environmental concerns regarding the impacts of cement production on the environment, namely the depletion of non-renewable fuel resources, consumption of natural raw materials, and releasing huge amounts of CO2 into the atmosphere should be, therefore, one of the key priorities of the cement industry. Application of locally available minerals and wastes that can be blended with OPC as a substitute could considerably reduce the environmental impact. The present study evaluates the potentiality of waste seashell to be used as an additive in the production of blended cement through a modified life cycle approach integrating environmental and mechanical performances. In this regard, 34 cements consisting of different blends of OPC, seashell powder (within the range of 4–30% by OPC mass), and natural pozzolan (up to 30% by OPC mass) were tested to identify the optimal dosage of OPC substitution. Environmental impacts of the cements were assessed through life-cycle analysis. The possibility of mitigating the carbon dioxide emissions in the production of cements, with similar mechanical performance compared to that of OPC, was evaluated by considering both the mechanical and environmental results. The outcome of this study introduced more environment-friendly and sustainable options for future cements.

This article presents the environmental assessment of geopolymer bricks produced from clay and waste bricks. The life cycle approach is the method used in this research to qualify, identify and compare the environmental impacts of geopolymer bricks and fired bricks. The results reveal that the manufacturing process of geopolymer bricks implies for the same compressive strength of fired bricks, a reduction of CO2 emissions by up to 55% for clay-based geopolymer bricks. This research checks the environmental interests of the application of geopolymerization technology in the production of bricks.

Financial Impacts

With the aim of moving towards a more sustainable society, hospital buildings are challenged to decrease their environmental impact while continuing to offer affordable and qualitative medical care. The aim of this paper was to gain insight into the main drivers of the environmental impacts and costs of healthcare facilities, and to identify methodological obstacles for a quantitative assessment. More specifically, the objective was to assess the environmental and financial impacts of the general hospital Sint Maarten in Mechelen (Belgium) by using a life cycle approach. The hospital building was analyzed based on a combination of a simplified life cycle assessment and life cycle costing. The “MMG+_KULeuven” assessment tool was used for the calculation of environmental impacts and financial costs. The study revealed that the environmental impact was mainly caused by electricity use for appliances and lighting, cleaning processes, material production, and spatial heating, while building construction and electricity use caused the highest financial costs. The most relevant impact categories identified were global warming, eutrophication, acidification, human toxicity (cancer and non-cancer effects), and particulate matter. Various methodological challenges were identified, such as the adaptation of existing methods to ensure applicability to hospital buildings and the extraction of data from a Revit model.

And Storage

Cement manufacturing is one of the most energy and CO2 intensive industries. With the growth of cement production, CO2 emissions are increasing rapidly too. Carbon capture and storage is the most feasible new technology option to reduce CO2 emissions in the cement industry. More research on environmental impacts is required to provide the theoretical basis for the implementation of carbon capture and storage in cement production. In this paper, GaBi software and scenario analysis were employed to quantitatively analyze and compare the environmental impacts of cement production with and without carbon capture and storage technology, from the perspective of a life-cycle assessment; aiming to promote sustainable development of the cement industry. Results of two carbon capture and storage scenarios show decreases in the impacts of global warming potential and some environmental impacts. However, other scenarios show a significant increase in other environmental impacts. In particular, post-combustion carbon capture technology can bring a more pronounced increase in toxicity potential. Therefore, effective measures must be taken into account to reduce the impact of toxicity when carbon capture and storage is employed in cement production. CO2 transport and storage account for only a small proportion of environmental impacts. For post-combustion carbon capture, most of the environmental impacts come from the unit of combined heat and power and carbon capture, with the background production of MonoEthanolAmine contributing significantly. In combined heat and power plants, natural gas is more advantageous than a 10% coal-saving, and thermal efficiency is a key parameter affecting the environmental impacts. Future research should focus on exploring cleaner and effective absorbents or seeking the alternative fuel in combined heat and power plants for post-combustion carbon capture. If the power industry is the first to deploy carbon capture and storage, oxy-combustion carbon capture is an excellent choice for the cement industry.

The environmental impacts of cement production using two pre-drying processes, i.e., coal-fired pre-drying process and pre-drying process by waste heat from kiln tail process were analyzed and compared through life cycle assessment (LCA). The results show that the energy consumption, GWP, AP, POCP, HT and EP of pre-drying process by waste heat from kiln tail are about 1%, 2%, 5.2%, 5% ,3.5% and 3.8% lower than coal-fired process; therefore the application of pre-drying process by waste heat from kiln tail has obvious environmental benefits.

The market of Adaptive Building Skins has been growing at a slow but incremental speed, as these technologies ensure better indoor climatic comfort and more efficient energy management than traditional solutions. Nonetheless, if we acknowledge the building as a system of physical qualities oriented to overall environmental performance, the resource optimization has to be extended to considering a wider range of environmental impacts along the entire building life cycle. For this purpose, the Life Cycle Assessment (LCA) method is recognized by stakeholders as the most world-renowned standardized tool for weighting environmental impacts. The aim of this study is to scrutinize the state of the art of LCA among stakeholders enrolled in the design and manufacturing of building and adaptive facades in the Italian market. Data have been collected throughout interviews and an online survey focusing on investigating the knowledge and experience level of participants. Results not only draw the attention to develop new market models by implementing sustainable building protocols concerning adaptive technologies, but also provided a positive assessment on the usability degree of a parametric design mapping based on a systemic and life-cycle-oriented approach to achieve environmental scopes and introduce competitive factors and boost innovation in the Italian building industry.
