2.2.1 Campus food waste tracking

Srinakharinwirot University (SWU) measures the food waste generated from food served on all of its campuses. Food waste is one of five categories in the university's waste management system. The other four are general waste, hazardous and infectious waste, recyclable waste and agricultural waste.

Food waste is measured each time it is collected. When the operator comes to collect it, the food waste is weighed on site and the weight is written in a paper logbook. Staff then enter the figures into the university's central spreadsheet. The spreadsheet feeds a waste management dashboard that reports waste by type, month and campus, so the university can track trends and plan ways to reduce waste.

In 2025, the data covered all twelve months and all campuses. The university produced 14,992 kg of food waste, which was 0.4% of the 3,340,672.76 kg of total waste. None of the collected food waste went to landfill because all of it was used as fish feed. Recycling and composting of other waste types also helped. Together, the university's waste management offset 195,965.57 kgCO₂e of carbon emissions.

The food waste data are publicly available on the university's waste management dashboard: SWU Waste Management Dashboard
