The influence of the material composition of surface-mount device (SMD) diodes on the environment has been analysed in this research. This impact assessment has been performed by means of an environmental impact calculation through a life cycle assessment (LCA), in which the EcoInvent dataset has been updated and customised, generating a more precise environmental impact analysis by considering the exact material composition provided by several suppliers of diodes and also recycling during the production stage. Considering the EcoInvent diode dataset as a reference, variations from nearly 1640% to only 8.5% of the environmental impact have been achieved. For example, the impact per 1 g of SMD diodes can change the global warming potential from 292 g CO2 eq up to 354 g CO2 eq, whereas for abiotic depletion, values can change from 9.9 × 10−7 up to 1.9 × 10−4 kg Sb eq. The presence of critical raw materials such as antimony, cobalt, or magnesium, together with precious metals as gold or silver, highly influences the environmental impact values obtained, demonstrating the considerable influence on the environmental impact of the material composition of the SMD diodes analysed.

The impact of tunnel construction upon the environment is analyzed from the perspective of ecology, air, sound and society respectively. In the case of Three Ponds Tunnel, risk assessment is made on the environmental impact in different stages of tunnel construction. Environmental protection measures are put forward, which can serve as reference for environmental protection in the construction of similar geotecnical engineering projects.

The Impact

In order to improve educational facilities and infrastructure, Department of Housing and Settlements, Depok City  plans to reconstruction a school building. With the impacts caused by this activity, an environmental impact assessment is needed. The purpose of this study is to obtain the results of an analysis of environmental impact studies and ways of mitigation in minimizing the impacts that occur during pre construction stage, construction stage, and operation stage. The method used is observation, interview and scoping methods to determine the impact and good handling of the environment. The results of this study are obtained an analysis of environmental impacts that occur during the activity and how to minimize the impacts with good handling in order to create an environmental friendly construction.

"The target of this paper is to show a methodology developed to establish the influence of material composition on the environmental impact, considering the presence of critical and strategic raw materials. A Life Cycle Assessment (LCA) has been performed to calculate the environmental impact, analyzing all the life cycle stages of the product. In order to achieve a more precise environmental impact analysis, EcoInvent database has been updated with primary data from product supplier’s data. Also, a new software tool, “Sustainable Electronics” was developed and used to calculate the environmental impact and raw material consumption. This methodology has been implemented on an induction hob, as it is a multipart product made of several components from electronics boards to metallic and plastic parts. The application of this methodology shows the huge influence of material composition on the environmental impact of the product, helping engineers to design more sustainable products."

The Impact

The objective of the undertaken study is to assess the application of Building Information Modeling (BIM) and evaluate the quality of information on construction projects. The paper also focuses on examining the design information quality on construction projects by applying BIM based on perceived variables, for instance, improve workflow, improve collaboration, design visualization, lower cost, environmental impact analysis, and variations. The first objective was to evaluate the impact of building information modeling on perceived variables such as improve workflow, improve collaboration, design visualization, lower cost, environmental impact analysis, and variations. We also evaluated the impact of these six constitutes of BIM, for instance, improve workflow, improve collaboration, design visualization, lower cost, environmental impact analysis, and variations on reducing design information problem. Finally, we have evaluated the mediating impact of improve workflow, improve collaboration, design visualization, lower cost, environmental impact analysis, and variations between building information modeling and reducing design information problems. In the last, we also examined the impact of BIM on reducing design information problems. In this context, the closed-ended five-point Likert scale adapted questionnaire was distributed among construction professionals, and data were analyzed through structural equation modeling and multivariate techniques using statistical software. The findings demonstrated that BIM has a significant & positive impact on its six constitutes. Additionally, we examined these constitutes such as improve workflow, improve collaboration, design visualization, lower cost, environmental impact analysis, and variations have a significant impact on reducing design information problems. The results also significantly contributed to the fact that BIM has a significant impact on reducing design information problems, ultimately playing a pivotal role in assessing design information quality on projects.
