This project aims to design a waste collection system that is not only desirable but also feasible in Taiwan. We adopted Design Thinking approach. First， we conducted a case study to understand the waste collection systems among 7 countries and sorted out 3 strategies， including facilities， motivations ＆ behaviors， and awareness. Second， we used grounded theory to explore the relationships between the sanitation worker （the service provider） and people （the user）， and 5 aspects were revealed， including user's attitude， provider's attitude， direct interaction， indirect interaction， virtual interaction. Third， we led co-creation workshops and uncovered people’s needs and expectations in 3 aspects. They are internal incentives， external restrictions， and behaviors. Based on the results， we concluded 2 design guidelines， easy to maintain and clear guidance， and the design opportunity， providing an unhurried way to throw away household waste. Finally， we delivered three design concepts: “as long as you need”， “1-day station”， and “1-hour station”.
