Waste and Resource Sorting

At SFC, we promote waste sorting and recycling to reduce our environmental impact and create a sustainable campus. As part of this effort, we have created a "Waste and Resource Sorting Dictionary" that allows you to easily look up sorting methods in Japanese alphabetical order. Please make use of it.

*To search for a specific type of waste or resource, please use your browser's in-page search function.
