On November 13, the 7th seminar of Pre-emptive LCA Social Cooperation Research Department was held at Hybrid. The lecture was “LCA for Architecture and Evaluation of Various Perspectives” by Professor Tsuyoshi Seike (Graduate School of Frontier Sciences). There were interesting discussions. Oneo of them was whether aluminum used in construction is best reused in cars or architecture. The seminar made us rethink issues that transcend industry.
