日本通产省最近发表报告,提出了实现资源循环利用的4类重点技术,以建立“循环型经济社会”。这份题为《关于构筑循环型经济社会所需要的技术课题》的报告说,为了实现社会经济的可持续发展,解决环境问题,应该大力发展长期使用、循环利用资源的各种“循环技术”。 该报告提出的构筑“循环型经济社会”所需要的4类“循环技术”是:①尽可能减少资源和能源投入量的技术。如利用新能源、节约能源和资源的技术,应用微生物等生物功能的资源再生技术等。②延长产品使用寿命的技术。如预测产品寿命的技术,有助于降低维修成本的技术,更新产品功能进一步延长产品寿命的技术,高性能、长寿命材料的制造技术等。③有效的循环利用技术。如用易降解材料制造高质量产品的技术,易于循环利用的材料制造技术,分离和提取有用物质的技术,提高热循环
Japan’s MITI recently issued a report, put forward four kinds of key technologies to achieve recycling of resources to establish a “recycling economy and society.” The report titled “Technical Issues Needing to Build a Recycling Economy and Society” said that in order to achieve sustainable socio-economic development and solve environmental problems, various “recycling technologies” for long-term use and recycling of resources should be vigorously developed. . The 4 types of “recycle technologies” required by this report to build a “recycling economy and society” are: (1) Techniques for minimizing resources and energy inputs. Such as the use of new energy sources, energy conservation and resource-saving technologies, the application of biological functions such as microbial resources regeneration technology. ② extend the life of the product technology. Such as technology that predicts product life, technology that helps reduce maintenance costs, technology that updates product functionality to further extend product life, manufacturing technology for high performance, long-life materials, and more. ③ effective recycling technology. Such as the technology of producing high quality products with easily degradable materials, the manufacturing technology of materials that are easy to recycle, the technology of separating and extracting useful substances, and improving the heat cycle
