Invitation message

We are pleased to announce the 4th International Conference on Final Sink (ICFS) to be held at Kyoto Research Park in Kyoto, Japan, from the 25th to 27th of October, 2017. The conference will be jointly organized by Kyoto University, the National Taiwan University, Vienna University of Technology, and International Solid Waste Association. Since the first conference in Vienna, Wein in 2010, it had been held in Europe twice and then in Asia once. Seeing the great success of the third conference in Taiwan, it is our great honor to be able to host the 4th conference here in Kyoto.

It is of great significance to hold 4th ICFS successively in Asia again because the 21st century is the time when a true harmony between environmental preservation and economic development is required, approaches on clean cycles and safe final sinks in Asia have only just started, and Asia is regarded as the next economically growing region.

Dr. Paul H. Brunner, Professor Emeritus at Vienna University of Technology, first stressed the necessity of shifting to a focus on studies from material flow analysis to sustainable material management, which led to the development on Final Sink in the 21st century. In 2015, Prof. Hwong-Wen Ma of National Taiwan University took the initiative to host the 3rd ICFS with the subtitle of “From Product Design to Clean Cycles and Safe Final Sinks”. I recognize this move and their messages from their past efforts as follows. Under the circumstances that we are required to shift our stance to cyclical use of resources, we must find ways of management and control of hazardous substances as well as policies for final sinks.

The 4th ICFS will especially focus on Life Cycle Thinking, raising awareness of “How can cleaner production and waste prevention reduce the need for sinks ?”. In order to estimate material flow and resource efficiency in the next generation of sustainable societies, it is our great challenge to realize cleaner production and prevent waste generation. The conference welcomes such presentations and proposals that will benefit for Asia where environment-friendly economic growth is needed.

Kyoto was once a capital of Japan, having a wonderful history going back to more than 1,200 years. It has many beautiful temples and fine cultural heritages, and you can enjoy yourself in its relaxed   peaceful atmosphere. In addition, Kyoto is widely known as the city where the Conference for the Flame Work Convention on Climate Change successfully adopted Kyoto Protocol in 1997. Kyoto University located in this fine city is one of the leading universities in the world. Since its establishment 110 years ago, it has produced abundant great research results in a broad range from natural science to humanities. I am looking forward to spending pleasant time with you in Kyoto in autumn when the leaves in the city turn beautiful colors of red, yellow, and orange.
