organic waste management

การจัดการขยะอินทรีย์ในมหาวิทยาลัย

The organic waste generated at Roi Et Rajabhat University consists of fallen leaves and food waste from the university cafeteria and the demonstration school. This waste is systematically managed.

For the leaves, they are used to make compost by creating compost enclosures at the base of trees or sweeping them into piles around the base without burning. Leaves with special characteristics that can produce color are used for natural fabric dyeing and eco-printing. Larger leaves are turned into biodegradable packaging through a process of molding with pressure and heat.

Food waste from the cafeteria and the demonstration school is used to feed BSF (Black Soldier Fly) larvae, which are then used to feed laying hens and catfish on campus. The remaining food waste is donated to network farmers who raise BSF larvae and use it for composting, helping reduce agricultural costs in the community.

การนำใบไม้มาเป็นวัสดุสำหรับการย้อมสีธรรมชาติและทำผ้าพิมพ์ลายธรรมชาติ (eco-printing) เพื่อสร้างมูลค่าเพิ่มให้กับเศษวัสดุ และเป็นการฝึกการเรียนรู้ และสร้างรายได้ระหว่างเรียนให้นักศึกษา 

Using leaves as materials for natural dyeing and eco-printing adds value to waste materials while providing students with hands-on learning experiences. This initiative also creates opportunities for students to earn income while studying.
