Dear Colleagues,

On behalf of Dr. Eng. Karolina Laszczyk and Dr. Anna Kamińska from the Faculty of Management at Wrocław University of Science and Technology, we are pleased to invite you to a seminar led by our guests from Tohoku University. The seminar will focus on interdisciplinary research in the fields of sustainability and engineering.

The presentations will be delivered by:

• Prof. Zhengyang Zhang, "Dynamic Material Flow Analysis of Alloy Steel Used in Car Engines"
• Prof. Binze Wang, "Hidden Material Flows Along Car Supply Chains: A Life Cycle Perspective"
• Mr. Kouki Tanaka (PhD Candidate), "Water Scarcity Impacts of Semiconductor Supply Chains and Mitigation Strategies"

The seminar will take place on:

11 June 2026, 11:15 a.m.
Building B-4, Room 44b

Speaker biographies

Prof. Zhengyang Zhang
Assistant Professor of Environmental Economics, Tohoku University

Dr. Zhang holds a Ph.D. in Environmental Studies from Tohoku University and has four years of industry experience at a Japanese waste recycling company. His research focuses on vehicle recycling, material flow analysis, life cycle assessment, and metal supply chain analysis, including steel, nickel, chromium, aluminum, and battery cathode materials. He also develops risk models for global critical metal supply chains. His work has been published in leading journals, including Nature, Resources, Conservation & Recycling, and Environmental Impact Assessment Review.

Prof. Binze Wang
Assistant Professor of Environmental Economics, Tohoku University

Dr. Wang earned his Ph.D. in Environmental Studies from Tohoku University in 2025 and holds dual bachelor's degrees in Mining Engineering and Economics from the University of Science and Technology Beijing (USTB). His research examines the links between mining-related environmental impacts and economic activities along mineral supply chains. His interests include tailings generation, soil and water contamination, and mining-induced land-use change. His methodological expertise spans industrial ecology, geospatial analysis, machine learning, and mining engineering.

Mr. Kouki Tanaka
PhD Candidate, Graduate School of Environmental Studies, Tohoku University

Mr. Tanaka's research focuses on supply chain analysis in the semiconductor industry and its impacts on water resources. He is developing methodologies for mapping complex semiconductor supply chains, with particular applications to silicon wafer production. His doctoral research aims to extend supply chain analysis to a broader range of products and wider system boundaries, contributing to sustainability and resilience strategies for semiconductor supply chains.

We warmly invite you to attend!
