循環型社会と低炭素型社会を両立させる廃棄物処理技術

人間活動の代謝産物として発生する一般廃棄物の処理責務が課せられている市町村においても，低炭素型，循環型の処理システムの構築が求められている。本研究では，現在のわが国における一般廃棄物処理の現状を俯瞰し，その課題を抽出するとともに，新たな技術としてRecyclable Landfill System (以下，RLシステム) を提案した。RLシステムとは，廃棄物埋立地の埋立空間を焼却残渣セメント原料化のための脱塩施設として繰り返し利用することが可能な持続型環境技術 (Sustainable Environmental Technology) を取り入れたシステムであり，循環型社会のみならず，低炭素型社会にも貢献する技術である。

Digestion and degradation, air for life

Anaerobic degradation of dead biomass is a natural gasification process, an anaerobic crematorium producing a very useful end-product composed of methane and carbon dioxide, generally polluted with small amounts of some malodorous and quite toxic volatile S-compounds. It leads to the production of essential building elements for new life. This exciting field became my faith, vision, hope and expectation. This paper intends to present a reflection of more than three decades of research, teaching and advertisement in the field of sustainable environmental protection technologies, particularly of systems based on anaerobic digestion and the biological sulphur cycle. Considerable progress has been made during these decades worldwide, both in the basic understanding of the various processes and concepts, but also in the implementation of these systems, despite the fact that particularly the implementation frequently proceeded very laboriously. The difficulties certainly can no longer be attributed to technological limitations and/or insufficient understanding of the microbiology and chemistry only, but mainly to the frustrating social rigidity and short-term self-interest in all sectors of our society. By combining anaerobic processes with other microbiological degradation or transformation processes, like those based on the biological sulphur cycle, micro-aerobic and conventional aerobic and anoxic processes, ideal conditions can be created to valorise residues (wastes) from domestic, industrial and agricultural origin. It is simply not just "technology", but also a route to achieve more sustainability and justice in society. It is a fight against conservative establishments. Decomposition, disintegration disbandment, it also stands for deliverance and liberation, space and air for continuation of life.

Sustainable development and environmental technology: a comparison of policy in Japan and the European Union

The concept of sustainable development, is increasingly being proposed as a means to avoid the impasse between economic development and environmental protection. In this paper, the incorporation of the concept of sustainable development into policy-making in both Japan and the European Union is examined. A particular variation in response between the two has been in relation to encouraging the development of environmental or clean technologies, a key element in achieving sustainable development. The benefits of an early lead in environmental technology may result in gains to the economy. In this paper, the potential commercial gains from the integration of environmental policy with industrial, development are also examined.

European Union Sets Competitiveness Vision For The 21st Century

The European Union—formerly the European Community—has issued a new and comprehensive industrial competitiveness policy aimed at bringing that 12-nation partnership (soon likely to be 16) to parity with the high-technology economies of the U.S. and Japan. Called An Industrial Competitiveness Policy for the European Union, the document provides a frank assessment of the EU's problems and lays out a plan for bringing its institutions into an era in which sustainable development, biotechnology, environmental technologies, energy and transportation systems, and information and telecommunications are seen as inevitable sources of employment and economic growth. The plan lays out actions needed in four priority areas if the EU is to become competitive in high-technology products. These areas are promotion of intangible investments in such areas as research, worker training, and environmental quality; development of new models for industrial cooperation; fairer competition inside the EU as well as at an inte...
