Conference Introduction

The 2025 GREEN Innovation & Engineering International Conference (GREENIE 2025) is an international conference dedicated to life cycle management and green engineering. It is hosted for the first time by the Taiwan Society of Life Cycle Assessment (TWLCA), co-organized by the Institute of Life Cycle Assessment, Japan (iLCAj) and the Green Engineering Program Team of Taiwan’s Ministry of Education, and will be held at National Taiwan University from September 21–24, 2025.

The conference brings together academic experts, industry leaders, and policymakers from Taiwan and abroad to explore how green innovation can drive sustainable development and transform engineering practices. Its themes span sustainable production and consumption, climate solutions and decarbonization strategies, corporate sustainability and policy, assessment methods, and social engagement. With around 100–150 participants from academia, industry, and government, GREENIE 2025 fosters knowledge exchange and cross-sector collaboration through research presentations, industrial dialogues, and practice-oriented workshops.

“From consumers to makers – turning waste into agency.” In an era of escalating plastic waste, our project seeks to transform consumers from passive recyclers into active makers within the circular economy.

By using open-source tools to convert everyday PET bottles into 3D printing filament, we demonstrate how waste can be regenerated into valuable resources. Beyond technical feasibility, our focus lies in the social and educational value: through hands-on participation, individuals can reframe their perception of waste, develop circular literacy, and practice sustainability in everyday life.
