This study surveys the operation modes, results and problems of the waste container recycling system in
Taiwan, known as the Four-in-One Program, and compares the collation and time trend analysis of the program’s results
(such as the garbage clearance volume, the recycling rate of recyclable resources, the price of plastic “Due Recyclable
Waste Containers” (DRWCs), among other variables). The results show that the Four-in-One Program in Taiwan could
prevent waste generation and increase recycling weight and that the program’s key contributing factors are the collective
environmental consciousness, subsidies, and the resources recycle fee (RRF). However, the decreasing trends of the daily
per capita garbage clearance volume in Taiwan and Japan might be because the Four-in-One Program’s municipal garbage
collection teams check the trash to retrieve recyclable resources.
