Next-generation Material Stock that Realize the Full Potential of Resources

Hiroki Tanikawa


Since 1998, the Tanikawa Laboratory in Nagoya University is estimating and evaluating the weight of human activity, and particularly attempting to elucidate how much material has been used in industrial processes. The physical weight of industrial life is reflected in buildings, roads, cars, furniture and other durable materials which provide crucial services to our society. This is the material stock of Society, which requires constant inflows of material from the Environment, and produces outflow wastes as well. Reducing the accumulated weight and improving the efficiency of the stock we already have are vital to achieving a more sustainable society.


This research focuses on material stocks, in particular infrastructure and buildings which together form half of Japan’s material stock. The objective is to provide a chronological and geographical overview of wealth and... [ view full abstract ]
