An ultra-thin decoupling capacitor device has been developed, and its thickness and volume are one-seventh and one-third of those of conventional ceramics capacitors, respectively. Low temperature deposition of high dielectric constant SrTiO3thin film and flexible polyimide film as a base material make the capacitor smaller drastically. Mn impurity doping into SrTiO3improves the capacitor reliability and Mo-based electrode successfully prevents the polyimide film contraction. The capacitor shows a large capacitance density of 3.2 nF/mm2, and low leakage current of 10-7A/cm2at 10V with only a 40 μm thickness. This capacitor device is suitable for developing eco-friendly electronic products.

A world new simple electronically sheath heated self-disinfection secateur, an experimental prototype kit has been designed and made for alternating chemical disinfection of the blades. A battery with capacity of 7.2 V is designed to hung on worker's waist belt. Hence, the battery enables heating blades at more than 100 °C for about 3 hours in a field operation. This battery operated heating secateur should contribute in economy of harvesting by protecting from contagious disease transmission and in saving farmers from routine time consuming disinfection work by chemicals in every cutting.

This paper describes experiences from several years of DfE studies at different manufacturing companies, as well as their strategies for approaching DfE. The general experience from the authors is that in order to make DfE truly utilized, it must become a "living part" of the company. To reach this point, it is important to obtain a strong commitment not only from the manufacturing company's management, but also from other DfE stakeholders throughout the company, at both the strategic and operational levels. DfE initiatives must be considered as a strategic issue and an investment in increased competitiveness. When summarizing all the experiences presented in this paper, a conclusion is that manufacturing companies often have a need for a general model that focuses on how to make "DfE thinking" a natural part of the company's way of doing business

In Japan, it has been becoming necessary to improve transportation environments suitable for elderly people and physically challenged people. But basic solutions based on an improvement in many infrastructures have political, economical and ecological limitations. So, we have to make other social strategies for creating universal transportation environments for the future. In this research, we had three persons disabled in their legs use "iBOT™", a transporter which empowers you to climb curbs and easily traverse grass gravel, sand, mud, puddles and other forms of uneven terrain and enables you to climb up and down stairs. As a result, it has been clarified that "iBOT™" gives them the following ideas: (A) lengthening average time needed in traveling, (B) diversifying their purposes of traveling (C) giving them more chances to travel without using buses and their own cars. Moreover this study has clarified the social interface of "iBOT™" and some technical points for improvement in Japan. We suggest a new solution for creating efficient and ecological universal transport environments by using the future wheelchairs.

An indispensable approach for realizing the sustainable society is to propose and discuss visions that indicate directions of our society and technological development. I have proposed Vision 2050 that suggests requirements for constructing the sustainable society in terms of energy and material circulation. Japan has confronted emerging issues, including the environmental contamination, shortage of energy resources, and shortage of final disposal sites, as a front-runner of the world and these issues are getting severer and severer especially in Asia. In this sense, Japan should work as a front-runner in EcoDesign area so that Asian countries can absorb various hints for solving these problems. And one of the key technologies is "structuring knowledge."

This paper assesses the life-cycle of packaging materials designed to protect large-scale integration devices from shock and static electricity when they are transported from semiconductor factories to printed-circuit-board factories. Carbon dioxide (CO2) emitted during production and incineration was reduced by 11% when embossed plastic tape packaging made from non-renewable sources was replaced by material made from bio-based polymer

Product Service System (PSS) concept aims at minimization of environmental impacts with alternative form of product utilizations and services, while maintaining enterprises economical performance and service quality for users. In this study, a methodology to analyze PSSs with life cycle simulation is proposed. This approach enables the authors to systematically describe diversity in form of PSSs, and to evaluate and compare alternative PSSs from environmental and economic perspective. Case studies quantitatively imply the feasibility of further sustainable PSS by integrating existing PSSs

This study examines both economic and environmental performance of an industrial park using the eco-efficiency indicator framework. The case study involves Chang Hua Coastal Industrial Park (CHCIP) and its surrounding area in central Taiwan. An eco-industrial cluster consisting of seven companies and anchoring a large steel mill was identified for recovering of waste generated into construction materials. (It was referred to as being 'eco-industrialization' hereinafter). The eco-efficiency of individual companies and the overall eco-efficiency of the total system were quantified using one economic indicator (after-tax profit) and five environmental indicators (energy consumption, water consumption, raw material consumption, CO2 emission, and total waste generated). Five eco-efficiency ratios were estimated under three scenarios of the park: before the clustering system is formed, after the clustering system is formed, and a future optimum scenario (i.e. for situations the goal of "zero emissions" is being achieved). Results of this study demonstrate that overall eco-efficiency of the cluster following eco-industrialization could result in increases of up to 30-40% over the pre-eco-industrialized level

Today, solar energy is seen as one of the auspicious renewable energy sources. At the beginning of solar cells history in the 1950th, solar cells were labeled as adverse due to their high energy payback time and low efficiency, therefore their application were limited to aeronautic and astronautic fields as well as to small applications such as pocket calculators. Recent developments resulted in the improvement of the energy efficiency of solar cell modules, as a result, the solar cell modules became more competitive to other renewable energy resources. In this paper the EU funded project SENSE is presented, which aim is to develop a recycling system for thin film solar cells. An accompanying LCA study shows the environmental impact of the considered solar cell systems
