In order to promote steel can recycling activities in Japan, the Japan Steel Can Recycling Association implements the "Questionnaires on the Recycling of Steel Cans" which summarizes the situation of steel can recycling in the municipalities and estimate a recycling rate. To estimate recycling rate among municipalities are based on answers of recycling quantity of steel cans from sorted collection and non-combustible waste. However, only a few municipalities know the exact quantity of steel cans from non-combustible waste. To identify the average quantity of steel cans which containing in con-combustible waste, we conducted a waste composition analysis research on 6 municipalities.
Reduction of moisture in kitchen waste is effective for combustible waste reduction. In this research, effectiveness of four countermeasures prior to incineration, such as manual dewartering at sources, drying of kitchen waste, drying of combustible waste and recycling of kitchen waste, against the amount, heating value and treatment cost of combustible waste were estimated and compared. The results showed that "drying of combustible waste" was most effective in reducing its amount and enhancing high heating value. However it was most costly, and "recycling of kitchen waste" was rather cheap.
Using the information listed in official reports, such as the implementation status report of the businesses discharging a vast quantity of waste ,the status report of the industrial waste manifest issue, the status report of the electronic manifest registration, and the performance reports of the industrial waste disposal businesses, we attempted to develop a dataset to link the industrial waste logistics from generation to treatment, final disposal or recycling, and to draw out the whole picture of industrial waste flow in a certain administrative area.
It is the problem that the transportation efficiency of the rverse logistics contributes to the carbon footprint in the transportation section, and is important for securing of recycling and fitness processing of the waste.In this study, we estimated the modal shiftable amount by using data from industrial waste disposers.As a result, it was revealed that by reducing the size of the vehicle and modal shift to the ship, transport costs and carbon dioxide emissions, which indicate the degree of transport efficiency, can be reduced by 60% and 20%, respectively.
This study aims to grasp the current situation of environmental education centers that attached to the MSW (municipal solid waste) treatment facility by studying the positioning and classification of these facilities as a kind of the social education facility and to discuss the direction and challenges for the future research.
Since it has been banned to import plastic matters as waste in China last year, Japanese recycle market for plastic bottle has been trembling. More attention was given to the severity of marine litter and restrictions on the use of disposable plastic materials began to be enacted at overseas. It is now more necessary to expand the idea and taking action of 2R (Reduce and Reuse) than recycle. Along with providing an event called “2R Tea Ceremony” for local people to learn preparing tea properly, there is opportunity to consider the reality of mass consumption of plastic bottle. By learning how to make tea properly, not only reducing waste such as plastic bottles was introduced, but also it was mentioned that helps preventing global warming, carrying on culture, sustaining local industry and etc. First, it explains the reason why green tea was selected for this study. Then, the achievements of “2R Tea Ceremony” will be introduced in this paper as: 1) awareness on reducing plastic bottle, 2) progress in acceptability for the matter by collaboration between events and seminars, and 3) development through cooperation between various stakeholders such as tea industry and region.
Whatever, municipal solid waste(MSW) is left in the environment, problems arise in terms of public health. On the other hand, although the MSW disposal facility is a socially necessary facility, however there is a fear that residents around the facility will be annoying facilities that could cause serious risks such as traffic pollution and fear of leakage of pollutants is there. Nuisance facilities are one of so-called public goods (public services) that anyone can use and benefit society as a whole. However, there is a serious discrepancy between the recognition of society and the recognition of the risk between the local residents, which may develop into a serious conflict over the allocation of risk. It is so-called NIMBY (Not in my backyard). NIMBY by local residents admits the social need, but that it is not allowed to be located in your own backyard. We will clarify the fact that the interests of majority socie
The interest in microplastics by citizens is considered to be steadily increasing; however, we do not grasp the level of citizen consciousness to microplastics. Therefore, in Osaka, we conducted educational events, lectures, and observation meeting on microplastics and surveyed citizen awareness of microbeads contained in products such as facial cleansers. There were 116 responses to the questionnaire. Aggregation of how respondents answered questions on the question of whether or not a facial cleanser containing microbeads had been used and analyzing the result by cluster analysis revealed that the existence of a group of “cautious” and a group of “no special measures are necessary”. However, in the analysis result, the answer “We should see the situation” exists independent of a group of "no special measures are necessary” and it turned out that there was a group with the middle ground.
The incineration rate of municipal solid waste in Sweden is 48%. All the 34 incineration facilities in Sweden utilize incineration heat for district heating (DH). The scale of district heating is expanding in Sweden. How much thermal energy is recovered from the incineration process and used for DH? Why and how increased use of incineration heat is expanding? This paper first grasps the statistics of the whole country, followed by a case study. That is, by analyzing the interaction among relevant actors on incineration heat use, the paper tries to explore the governance factors of increased use of incineration heat for DH.
As a result of the analysis, it was found that expansion of incineration heat and its use for DH is positioned as a sustainable energy strategy for low carbon economy rather than aiming sorely at waste management. On the other hand, it can be seen that the various governance conditions that are characteristic of Sweden, i.e. decentralization, expansion of new public management, the determination of environmental goals by political leadership and civilian control, are in the background of the increased use of the incineration heat.
