  • A 'Resource recycling society' is the common goal to reduce environmental impact from human activities and to conserve natural resources. The Resource-Recycling Waste Management is necessary to explicitly show objectives, and to evaluate the achievement level gained by school administration. In this paper, focusing on resource-recycling school waste management, three indicators are designed to evaluate the present conditions of school waste management, which include evaluation of school policy, waste management and education for waste management by school administration. Each indicator is made up of three or four questions that are supposed to be answered by school managers, teachers and students. Questionnaire surveys, which is based on the resource-recycling school waste management indicators, were carried out in elementary school, middle school and high school in the National Capital region. The resulting of indicators well describe the situation of school waste management among these schools. Influential strategies towards resource-recycling school waste management have been found in analysis.

  • Since the Framework Act on Resource Circulation was enacted in 2018, the government should establish a National Resource Circulation Master Plan every 10 years, which defines mid- to long-term policy goals and directions on the efficient use of resources, prevention of waste generation and recycling of waste. In addition, we must set mid- to long-term and stepwise targets for the final disposal rate, recycling rate (based on sorted recyclable materials and recycled products), and energy recovery rate of wastes, and relevant measures should be taken to achieve these targets. However, the current industrial waste (IW) statistics have limitations in setting these targets because the final disposal rate and recycling rate are calculated as the ratio of the recycling facility input to the IW generation. In this study, the material flow from the collection stage to the final disposal of industrial waste was analyzed based on the generation of 2016, and the actual recycling amount, actual incineration amount, final disposal amount and their rates were calculated. The effect on the recycling, incineration and final disposal rates was examined by changing the treatment method of nonhazardous wastes from the factory and construction and demolition wastes, which were put in landfills in 2016. In addition, the variation of the waste treatment charge was investigated according to the change of treatment methods. The results of this study are expected to be effectively used to establish the National Resource Circulation Master Plan and industrial waste management policy in the future in South Korea.

  • Recently, it is necessary to establish an eco-friendly construction system through recycling of waste material management at construction sites. This is required to reflect the times that require a carbon reduction system in construction as part of domestic and overseas carbon dioxide reduction. Therefore, we intend to establish eco-friendly construction management as part of resource recycling and carbon reduction through recycling technology for waste fibers generated at construction sites.

  • Solid waste disposal and management is a critical problem in Nigeria. Annually, a huge quantity of municipal solid waste is generated in Aba. Municipal solid waste disposal in Aba poses severe challenge to environmental safety, public health and welfare of citizens. The situation is made worse by the indiscriminate dumping of refuse at roadsides, streets, waterways and empty lands. The impact of this waste management practice in Aba is environmental deterioration. Efforts to improve waste management in Aba have not recorded significant success. This paper therefore aims to highlight the challenges facing the waste management sector in Aba and proffer solutions on how to improve the sector.

  • Upcycling generally refers to the conversion of waste materials to something useful or valuable and is a useful concept that can be applied not only to the waste design industry but also to waste recycling and resource circulation. Our study highlights upcycling as the key concept for improving the value of waste by redefining the concept as "the recycling of waste materials and discarded products in ways that enhance their value." Four upcycling strategies are linked to material flow analyses conducted on waste electronic and electrical equipment, specifically waste refrigerators and waste computers, to examine the technologies available for implementation and suggest guidelines for the promotion of upcycling. The amount of waste refrigerators collected by the formal sector was 121,642 tons/y and the informal sector, 63,823 tons/y. The current recycling ratio of waste refrigerators was estimated as 88.53%. A total of 7,585 tons/y of waste computers were collected by the formal sector and 3,807 tons/y by the informal sector after discharge. Meanwhile, the current recycling ratio of waste computers was estimated as 77.43%. We found that it is possible to introduce 28 upcycling technologies in the case of refrigerators, and 15 technologies are available to promote upcycling in the case of computers. By refining the broad concept of upcycling and looking at the stages of material flow, our approach presents universally applicable directions for incorporating upcycling in resource recovery and recirculation plans.

  • The waste home appliances including television sets, refrigerators, washing machines and air conditioners have increasingly received environmental concerns in Taiwan. In light of the enforcement of Waste Disposal Act (WDA), the Taiwan Environmental Protection Administration (EPA) has certified 60 recycling/storage facilities and given permission for qualified companies to build six treatment plants around the island. Now the recycling and well treatment home appliances are estimated to be 3,342,369 units until May 31, 2001. This paper describes the present status of waste home appliance recycle and its treatment in Taiwan. The principle guidelines and policies regarding recycling, resource recovery and environmental concerns are presented.
