AbstractFrom the results of the attributional life cycle assessment (LCA) of the bioethanolâbased polyvinyl chloride (PVC), shown in the first part of this work, changing the feedstock from fossilâ to bioethanolâbased ethylene appears to be a way to decrease the environmental impacts of that product on climate change and nonârenewable resources. Although, other environmental concerns may rise related to the effects of indirect landâuse change (iLUC) caused by sugarcane expansion. Therefore, the objective of the second part of this work was to make a consequential LCA of the bioethanolâbased PVC, assessing the effects of iLUC as the key sideâeffect of the implementation of that product in the market on 2018, at different degrees of iLUC (three scenarios were created). The life cycle inventory was collected from literature, databases, and primary data from Solvay S.A. We used midpoint and endpoint indicators for life cycle impact assessment. At the midpoint indicators, the environmental impact categories responded differently for the different degrees of iLUC, and some of them generated gains to the environment in the three scenarios, including nonârenewable resource use. At endpoint level, the results showed overall environmental gains if iLUC was kept below 5.7% of the sugarcane cultivation area. The effects of iLUC are based on assumptions, and therefore subject to uncertainties, but the assessment performed in this paper was important to provide quantitative information for the stakeholders on how the environmental gains of the bioethanolâbased PVC should not be nullified by iLUC impacts. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd |

SummaryLife cycle assessment (LCA) studies include a vast amount of different products. Often, extrapolations are necessary to obtain the life cycle inventory of a specific product. This article provides quantitative scaling factors with power (heat output) for product properties and life cycle impact assessment results of heat pump and biomass furnace technologies. Included in the study are 508 heat pumps and furnaces with differences in power over three orders of magnitude per product group. The key properties of the heat pump system were defined as mass, refrigerant use, and coefficient of performance. For the biomass furnaces, the key properties analyzed were mass, electrical input, and efficiency. The results indicated that both the mass and the refrigerant use increased subproportionally to power. For coefficient of performance and furnace efficiency, no scaling effect was found. Subproportional growth was found between two environmental impacts (global warming and ozone depletion) and power for the production phase. This scaling behavior was similar to conventional cost scaling. The results of our study imply that in LCA, scaling factors can be applied to estimate key properties and corresponding life cycle impact assessment results. This is particularly useful for prospective technology assessments with limited data available. |
