Life cycle assessment of different alternative materials used for stabilization/solidification

The main objective of this paper thesis is to determine the environmental impact of two houses made of two alternative materials - a wooden and a brick house - using a Life Cycle Assessment (LCA). By comparing the material composition of their design to determine the environmental impacts of global warming, human health, consumption of resources and ecosystem quality. An overall comparison showed that the materials for the construction of a wooden house have less negative impact on the environment than materials for the construction of a brick house. Using the GWP method, results show that the materials for the construction of a brick house leave twice the carbon footprint in the environment than materials for a wooden house. This resultant state is mainly due to the use of natural materials in the wooden house (wood, fibre insulation), unlike the materials used in the brick house (ceramic masonry, insulation from stone wool) and so on.

Scrap Aluminum

Changing the material composition of vehicles from steel to alternative materials, such as aluminum and magnesium, is being explored to reduce the weight of vehicles. Further, this change could lead to a significant reduction in vehicular CO2 emissions. To analyze this relationship and estimate the CO2 reduction effect over the life cycle, it is important to create potential scenarios by considering the logistics balance from material production to recycling. Therefore, this study aims to quantitatively predict the amount of renewable energy employed in vehicles, along with the various alternative materials used; further, the demand for aluminum and magnesium is predicted. These predictions are made via several multivariate analyses and a dynamic substance flow analysis (SFA) to explore future scenarios. It is estimated that 65% of rolled aluminum can be obtained from a secondary alloy via closed-loop recycling of rolled products in a sustainable development scenario. However, 510 kt/year of end of life scrap aluminum must be imported from overseas to provide 90% of the secondary alloy required in cast and die cast parts. The overall CO2 reduction amount is predicted to be 3920 kt/year in the 2040 sustainable development scenario. This study successfully demonstrated that combining SFA and life cycle assessment is efficient for quantitatively estimating the synergies of renewable energy implementation, vehicular weight reduction, and recycling.

Materials Used

This paper provides an analysis of the carbon emissions of materials used by a water company in the refurbishment of mechanical and electrical equipment at its pumping station. A tool for attaining life cycle calculations for embodied carbon, which can be applied in similar applications, is developed. Due to uncertainties in the derivation of numerical data and other related information, such as sources of raw materials, the embodied carbon emissions are calculated and analyzed using material emission factors using the Life Cycle Assessment method. This work may be used as a template for organizations requiring estimates of embodied carbon in materials and plant, for example, as a precursor to a major refurbishment project.

The present paper discusses the applications of life-cycle assessment (LCA) to construction works in Japan. LCA has been frequently used to assess the environmental impacts of new construction. Nonetheless, the applications of LCA to restoration have not been fully confirmed to date. It is said that historical buildings may contribute to sustainable development. Nonetheless, as for heritage buildings, since the protection of cultural value is usually prioritised, their environmental impacts may not be sufficiently explored. To this aim, this paper evaluated the environmental impacts of the restoration of heritage buildings. This paper consisted of two tasks. First, the restoration projects of heritage buildings in Japan were introduced. The restoration of two heritage houses was discussed, referring to heritage protection legislation in Japan. Second, LCA was performed on the restoration of heritage houses and the construction of contemporary houses. Environmental impacts were compared between the restoration and new construction with regard to greenhouse gas emissions and operational energy use. A focus was given to the amount of materials used. Restoration consumes a limited amount of materials compared to new construction, although the energy use of heritage buildings is considerable. The environmental impacts of restoration were quantified so that they were compared with those of new construction. The comparison indicated issues applying LCA to heritage buildings.
