“…The integration of both process-based LCA with EIO LCA [27,[84][85][86] into a consistent framework based on hybrid LCA [67,81,82,87] can provide much more robust results by expanding the system boundary and complies with ISO standards [88]. As this hybrid LCA process assesses the complete supply chain, providing full visibility, it is important to apply the methodology to cases such as those presented in this paper.…”

High volumetric efficiency capacitors are found in all smart electronic devices, providing important applications within circuits, including flexible filter options, power storage and sensing, decoupling and circuit smoothing functions. Multilayer ceramic capacitors (MLCCs) hold the major market share but tantalum electrolytic capacitors (TECs) provide a viable alternative if higher breakdown strengths are required. The reduced costs, smaller dimensions suitable for spaceconstrained electronic circuits, exceptional high-frequency characteristics, higher reliability, ripple control and longevity, however, are driving the market to replace TECs with MLCCs wherever possible. To date, no current research regarding the transition from TECS to MLCCs has been conducted from an entirely environmental viewpoint. This article identifies, quantifies, ranks and compares the environmental impacts of the MLCC and TEC supply chains using an integrated hybrid life cycle assessment framework. Three recovery methods: incineration; hydrometallurgy and pyrometallurgy are considered in the overall impact assessment. Electrical energy consumption during fabrication alongside the use of nickel paste are the major environmental hotspot for MLCCs. The high proportion of tantalum in TECs results in an overall greater environmental impact in comparison with MLCCs, due to intensive extraction, processing and purification requirements of tantalum. Of the three recovery methods, the hydrometallurgy process offers the least environmental impact for both MLCCs and TECs. Overall, the current work shows that while the industry led transition from TECs to MLCCs offers both an operational and functional edge, it is also an environmentally intelligent move. Intervention options that can further drive down the environmental impacts of MLCCs are also proposed such as a reduction in the reliance of MLCCs on rare earth elements and Cu external electrodes in some designs and material recovery.

“…The I-O method has been developed and implemented through several decades from the fundamental use to applied approach to some specific analyses such as water footprint, ecological footprint, CO2 and SO2 emissions, and energy embodied [Cláudia et al, 2014, Liu et al, 2015, Onat et al, 2014, Guill et al, 2015, Chen et al, 2015. Another highlighted method that constitutes an integration of the industry's processes and the economy is the hybrid of life-cycle assessment (LCA) and I-O analysis , Nagashima et al, 2016. This significant hybrid approach between LCA and I-O leads to the new hybrid model of physical and monetary units.…”

Abstract. Flooding is a common issue in many countries and can cause extensive damage to residential areas, agricultural and livestock areas, and public facilities. These damages impact the local economy directly and create unexpected demand for goods and services. The consequences of flood damage are marked by the ambiguity of how it changes the production of local economies. For this reason, our study implements the use of the hybrid I-O analysis to evaluate the economic effects of flood damages. The flooding scenario in Kochi prefecture, Japan simulated from the inundation model was selected to demonstrate the analysis. The influences of flood damages were divided into two stages, the garbage cleaning stage and the reconstructing stage; these two stages lead to the different scenarios based on the different activities. It was found that in total, flood damages could stimulate economic growth when the positive effect of reconstruction activities surpass the negative effect of garbage cleaning activities.

“…Furthermore, Hawkins et al addressed the technical coefficient of a mixed unit as direct requirements, which is illustrated by the calculation of lead flows and cadmium flows [27]. Recently, Nakashima et al (2016) evaluated the economic effects of constructing a wind power generation system [28]. The hybrid I-O analysis represents the integration of physical units and monetary units in one hybrid table.…”

This paper presents a new and improved method of hybrid input-output (I-O) to evaluate the economic impact of a biomass power plant's resource production and consumption. The effect of resource consumption induces a change in an economy's production structure and alters the technical coefficient of the hybrid I-O table, which should not be changed. Our study examines this problem based on two cases: a small cutoff ratio from the existing industry, in which the change in the technical coefficient can be ignored, and a large cutoff ratio from the existing industry, in which the technical coefficient is amended using the pre-adjustment method. Consequently, the biomass power plant using the large cutoff ratio from the existing industry case contributes about 1114 million yen to the local economy. A comparison of these two cases shows that the error caused by ignorance of the technical coefficient adjustment could result in 291.78 million yen less in total economic production, which is about 36% of the total additional production using the small cutoff ratio from the existing industry case. The losses in total economic production clearly increase in economic sectors that are related to the resource consumption of the biomass power plant.
