On October 18, the 6th seminar of the Pre-emptive LCA Social Cooperation Research Department was held at Hybrid. The lecture was given by Professor Yuko Tsunetsugu (Graduate School of Agricultural and Life Sciences) on “Toward Pre-emptive LCA of Wood and Woody Materials: Current Status and Issues of Research”. Although most of the participating companies are not directly involved with woody materials, they were impressed by the difference between biological and non-biological materials.
