The School of Science, University of Phayao, recently held a hands-on workshop on "Scientific Leaf Composting Without Shredding and the Use of Eco-Friendly Organic Waste Bins" on Thursday, October 22, 2026, at the Mae Na Ruea Health Promoting Hospital, Mae Na Ruea Subdistrict, Mueang Phayao District, Phayao Province. This activity is part of the "Scaling Up an Integrated Organic Waste Management Models Using Powdered Microbial Innovation for Low-Carbon Communities Development (Mae Na Ruea–Mae Sai)" project, bringing the faculty's research directly into the community to tackle waste problems in a practical way. The project is led by Asst. Prof. Dr. Reungruthai Sirirak, Associate Dean for Research and Innovation at the School of Science, who also joined the field team to share her expertise with local residents.
Dry leaves and food scraps are everyday organic wastes in the community. Leaving them to rot or burning them causes haze and greenhouse gas emissions. This workshop taught locals how to turn waste into fertilizer using scientific principles and powdered microbial innovation to speed up decomposition. The training focused on two main parts:
π± Leaf Composting Without Shredding: Making fertilizer straight from dry leaves without needing a shredder, saving both money and effort. Residents can easily do this at home and use the compost in their gardens or plots.
π± Eco-Friendly Organic Waste Bins: Managing household food waste right at the source, cutting down the volume of garbage sent for disposal, reducing odors and germs, and turning food waste back into nutrients for the soil.
The training team brought together experts from various fields at the School of Science:
π Assoc. Prof. Dr. Arrak Klinbumrung (Physics)
π Dr. Niyom Hongsith (Physics)
π Dr. Somrit Unai (Physics)
π Asst. Prof. Dr. Siriwat Boonchaisri (Biology)
They were supported by Mr. Prajak Khatthi, General Administration Officer, and Ms. Monruedee Manee, Supplies Analyst.
This activity highlights the School of Science's role in bringing science out of the lab and into everyday community life. The project helps locals manage organic waste on their own, reduces open burning and greenhouse gas emissions, and turns leftovers into useful household resources which turn Mae Na Ruea and Mae Sai into true models of sustainable, zero-waste, low-carbon communities.
