Canonical FY2568 annual report (10-03-69 DOCX, revision 129): waste measures, sorting/collection/disposal, waste data (general 4,380.10 kg, target −3% vs 2567 NOT met; total 6,434.70 kg; reuse 31.93%), wastewater control and treatment care. Category-level historical baseline — no signed/approved copy.
8-item waste measures plan (3Rs, bin layout, 4-category disposal, campaigns, monthly data). Thai text layer garbled (broken glyph mapping); content verified by cross-reference to the 4.1 section narrative which quotes item 6 verbatim. Glyph layer pending OCR.

Disclosure note: no foam-free declaration/campaign was conducted in FY2568; the FY2569 foam-free plan is a forward statement only (FOAM_FREE_FY2569_PLAN), not verified FY2569 evidence.
Participation campaign: cloth-bag service points (return-and-reuse) and reusable personal cups to reduce plastic waste.
Bin layout and sorting by category: 2 dining-area points (floor 3), 4 indoor points (floors 1–3), 1 outdoor 3-bay holding point.
Color-coded labels on every bin (blue general / yellow recyclable / green wet / red hazardous).
Covered, gated holding point (roof, rain/dust protection) + university central holding point beside อาคารเรียนรวม 80 ปี.

No waste burning on site; each category sorted and handled by the licensed contractor.
Annual scope: total all waste 6,434.70 kg, general waste sent for disposal 4,380.10 kg, reuse incl. food/leaves 2,054.60 kg (31.93%). Target −3% vs 2567 NOT met (+72.40 kg, +1.68%). Monthly-form scope total 5,625.7 kg recorded separately — never conflated.
Verified target analysis: 2567 4,307.70 vs 2568 4,380.10 kg → +72.40 kg (+1.68%), target −3% vs 2567 NOT met. 3-year table 2566–2568.
Reuse/recycling + innovation/composting: used-packaging upcycling, organic-waste composting, 3Rs seedling-planters at the ครั้งที่ 12 conference (4–10 พ.ย. 2568). Numeric >50% reuse threshold NOT met (31.93%) — claim rests on the innovation/composting branch.
Trend: 2566 4,633.10 / 2567 4,307.70 / 2568 4,380.10 kg. Down 253 kg vs 2566 but UP +72.40 kg (+1.68%) vs 2567 — the declining-trend claim is only valid on the 3-year window vs 2566.
