Environmental Load reduction by introduction of super water saving toilets at highway service areas in japan Environmental Load reduction by introduction of super water saving toilets at highway service areas in japan
2014Co-Authors: Naoko Nakagawa, Akira Kawamura, Hideo AmaguchiAbstract:Japanese highway service areas that have basic facilities such as car parking lots, toilets, and restaurants are required to be comfortable, clean, and safe. The Japanese highway management and maintenance company (NEXCO LTD) owns about 300 service areas where on average 80 toilets are installed in each service area. In these service areas, the scale of these facilities has been increased with around-the-clock operation for users’ comfort; therefore, water consumption, energy consumption, and accompanying costs have increased. The toilet facilities especially use large amounts of water and energy to treat the toilet’s drainage at each service area. Thus, toilets with low water consumption, low energy consumption, and comfort are indispensable at highway service areas in Japan. In this study, the Environmental Load reduction by the replacement of conventional toilets with newly developed super water-saving toilets, such as water-recycling urine-diverting toilets and waterrecycling urinals, at highway service areas in Japan was examined.Three different types of service areas were selected for the case study. The results obtained show that the Environmental Load from the service areas (i.e., water consumption and energy consumption) would be reduced greatly by introducing the newly developed super water-saving toilets.

energy and cost benefit evaluation of a urine diversion system a case study at highway service areas in japan
World Environmental and Water Resources Congress 2012: Crossing Boundaries Proceedings of the 2012 Congress, 2012Co-Authors: Naoko Nakagawa, Akira Kawamura, Hideo AmaguchiAbstract:In this study, the reduction on the Environmental Load by the replacement of conventional toilets with low Environmental Load toilets such as water recycling urine-diverting toilet newly developed at highway service areas in Japan was quantified and a cost-benefit analysis concerning introducing low Environmental Load toilets were performed. Moriya service area which is one of the large–scale service areas and Minori service area which is the middle–scale one were selected for the case study. As for the results, the pollution Load, especially, total nitrogen and phosphorous were expected to be reduced by 94% and 79 % from existed system, respectively, in the Minori service area. Concerning the burden of energy and cost, the payback periods by introducing the urine diversion system were 0.3 and 0.8 years for energy, and 2.8 and 12.6 years for cost at Moriya and Minori service area, respectively.

identifying lowest emission choices and Environmental pareto frontiers for wastewater treatment wastewater treatment input output model based linear programming
Journal of Industrial Ecology, 2011Co-Authors: Chen LinAbstract:Summary This article proposes a linear programming model that is based on the wastewater treatment input-output model (W2IO) to identify the lowest-emission choice among alternative feasible options for wastewater treatment; this model can be considered as an application of the waste input-output linear programming model (WIO-LP) to wastewater issues. Using the data of the Tokyo metropolitan W2IO table, I apply this model to obtain the optimal wastewater treatment options under alternative scenarios. The Pareto frontiers of Environmental Loads are derived to show the trade-off relationships among various types of Environmental Load and the effect of the introduction of high-temperature incineration of dewatered sludge on the generation of Environmental Loads. The main conclusion of the study is that when all three types of Environmental Load (landfill level, global warming potential, and chemical oxygen demand) are considered, the introduction of high-temperature incineration causes the widening of the Pareto frontier of Environmental Loads and also causes it to move closer to the origin.

embodied pollution in trade estimating the Environmental Load displacement of industrialised countries
Ecological Economics, 2002Co-Authors: Roldan Muradian, Martin Oconnor, Joan MartinezalierAbstract:Abstract The present paper sets out to aid in the development of ‘Environmental Load displacement’ indicators. Developing the notion of the ‘Environmental memory’ of physical flows, we estimated embodied pollution in trade of 18 industrialized countries with (a) the rest of the world and (b) developing countries, from 1976 to 1994. We found that in the last years of analysis, total imports of Japan, USA and Western Europe have entailed, in general, larger air pollutant emissions than local exports. The balance of embodied emissions in trade (BEET) seems to follow an inverted-U shape across time in Japan and Western Europe, and an N-shape in the US. In the period of analysis, Japanese and European Environmental terms of trade with developing countries ‘improved’ (from the Japanese and European point of view), whereas American Environmental terms of trade with developing countries ‘deteriorated’ over time. Although there is no statistical trend between income and embodied emissions in imports in a cross-section analysis, there does seem to be a positive relationship between both variables at a national level. The results suggest that, despite many shortcomings, this type of assessment may shed useful insights on the international aspects of sustainable development.

The results suggest that, despite many shortcomings, this type of assessment of embodied Environmental pressures in inter-country physical flows may shed useful insights on the international aspects of sustainable development. Particularly, on the distribution of the Environmental costs of trade and the relationship between economic growth and Environmental degradation.
