Based on the general policy called "Green Growth", the Korean government planed to establish a biomass town in South Korea in order to recover energy from organic waste and to substitute for fossil fuel at rural region. Technical and financial support for the establishment of biomass town was insufficient so far. There are some policies to support biomass town establishment, however financial support from several Korean ministries seemed not to have been used efficiently. Some policies are planned excessively so that they cannot be realized on time. Therefore, there is a need to analyze the status of biomass utilization technology and policy in Japan from the point of view of an external biomass expert, since biomass utilization technology and policy of Japan take good achievement during the many developed countries. For the analyzing of technology and policy in Japan, literatures concerned biomass management policy and biomass town design were collected by visiting Japan Ministry of Agriculture, Forestry and Fisheries and interview of public officials in charge was carried out. There are several implications for the promotion of Korean policy concerned with biomass utilization and biomass town establishment.

Controlling fashion waste throughout the entire product lifecycle is critical in a circular economy. This study explored the possibility of establishing a public recycling system for fashion waste. Since consumer interests and participation are essential, theoretical research, social-text analysis, and quantitative research were conducted to identify consumers' perceptions of the public recycling of fashion waste and circular fashion. Data were collected via an online survey among women in their 20-30's living in Korea, and 304 samples were used for data analysis. The results were as follows. First, consumers' perceptions of recycling fashion waste were composed of recycling difficulty, the need for public recycling, and the need for EPR. Circular fashion perception comprised favor, environment protection, attractiveness, economics, quality and hygiene risks, and lack of diversity. Second, the reuse-recycle attitude and need for EPR affected the favor of all types of circular fashion products. Third, environmental concerns impacted attractiveness, and the favor significantly affected the purchase intention of all types of circular fashion products. In particular, quality and hygiene risk negatively affected the purchase intention of used-fashion products, while attractiveness positively impacted the purchase intention of upcycled-fashion products. The results implied that discussing the public recycling system of fashion waste and EPR policy is imperative. The results also showed the need to classify different types of circular fashion products, such as used, upcycled, and regenerated fashion items, to examine consumers' perceptions. In addition, the recycling of the fashion waste scale developed in this study could be used for further research.

A policy for recycling waste concrete has been extensively studied, but it is still lacking to recycle and reuse as a cementitious powder, and the property has big different depending on the aggregate rates. In this study, the amount of cement powder according to the internal properties of the aggregate were mixed. From as a result, Concrete Powder to play inside the aggregate composition of the cement composition CaO rigs that causes loss of power and strength reduction due to rising real water cement ratio will affect large.

The first RDF production plant in Korea is going to start commercial operation at Won-Ju city in October this year, where municipal solid waste is treated and converted to RBF. Korean government is preparing the quality standard of RDF and starting a new waste policy of RDF promotion instead of general waste treatment technologies such as incineration or landfill. In Europe the EU member states have decided the united quality standard of RDF to increase the amount of new & renewable energy through the promotion of RDF utilization. New quality standard of RDF and trade market of RDF in Europe is introduced in this paper.

As one of renewable energy sources, biomass is playing a major role in reducing the greenhouse gas emission in the UK. The country currently produces about 4.5% (18.1TWh in 2006) of the total electricity generation from renewables, where biomass-based sources accounts for 50% of the amount and the remainder mostly from hydro and windpower. In 2007, the UK government has announced its new energy policy through the Energy White Paper, which includes an ambitious national target of 60% cuts in carbon emission by 2050. Complementary strategic plans in key renewable energy technologies accompanied the Energy White Paper, including biomass strategy, waste strategy and low carbon transportation strategy. This paper summarizes the current status and policy of UK for renewable energy production with focus on the use of biomass and bioenergy.

Recently, International Atomic Energy Agency and major leading countries in radioactive waste management tend to subdivide the categories of radioactive waste based upon risk-graded approach. In this context, the category of very low level waste has been newly introduced, or optimized management options for this kind of waste have been pursued in many countries. The application of engineered surface landfill type facilities dedicated to dispose of very low level waste has been gradually expanded, and it was analyzed that their design concept of isolation has been much advanced than those of the old fashioned surface trench-type disposal facilities for low and intermediate level waste, which were usually constructed in 1960's. In addition, the management options for very low level waste in major leading countries are varied depending upon and interfaced with the affecting factors such as: national framework for clearance, legal and practical availability of low and intermediate level waste repository and/or non-nuclear waste landfill, public acceptance toward alternative waste management options, and so forth. In this regard, it was concluded that optimized long-term management options for very low level waste in Korea should be also established in a timely manner through comprehensive review and discussions, in preparation of decommissioning of large nuclear facilities in the future, and be implemented in a systematic manner under the framework of national policy and management plan for radioactive waste management.

As amount of waste matter rapidly increases with fast growth of cities and industry, how to dispose them has arisen as an important problem. Current policy of the government on disposal of waste is repressing generation of waste itself and in case of already generated waste, resource cycle waste management system that recycles waste after proper environmental process is getting established. Therefore recycling of waste and industrial by-products is rising hugely. One of largely wasted matters is waste gypsum, which was categorized as designated waste but changed to general since 1994. Due to disposal cost and lack of impurities removal technology, recycling of it was quite low. However, as impurities removal technology using semi-dried desulfurization process is developed lately, study on recycling of waste gypsum is going on lively. This study examines possibility of utilizing waste gypsum as alternative for concrete cement and analyzed attributes of waste gypsum before and after ball mill process to find out proper alternation ratio, and conducted strength and property tests on concrete subject whose percentage of cement use is substituted with 0, 5.0, 7.5, 10.0 and 12.5% of waste gypsum.

Amid growing interest in recycling around the world, the amount of waste is increasing despite the separate discharge efforts of each household, and it is difficult to find accurate data on recycling household waste. Also, recycling segregation is already settled in our daily lives, but we face a serious problem in which a significant portion of the recyclables collected are re-waste. In this study has been proposed a cash compensation system for recyclables, which is paid cash when the recyclables are washed clean and discharged. The cash compensation system proposed in this study could re-use 100% of the discharged recyclables, resulting in rewards for good deeds for individuals, greater returns for businesses and reduced disposal costs for local governments. In addition, it is expected that the government will be able to secure data related to the recycling of domestic waste, which will contribute to the management of recyclables at the national level.
