This study was undertaken to characterize the solid waste generation at educational facilities in Hue, Vietnam. The authors surveyed 35 educational<br />
facilities within six categories of schools for seven consecutive days. The waste generation rates by facility, student, classroom, staff member, and floor area<br />
were assessed by school category using the following three waste categories: general waste (GW), separated recyclables (SR), and separated food residue<br />
(SFR). To determine the potential for composting and recycling from the disposal amount, GW was classified and measured by 10 physical categories and 77<br />
sub-categories. Plastic, paper, and food waste were dominant in most of the school categories. The total waste generated from educational facilities in Hue<br />
was determined by extrapolating the total number of facility/student in Hue and the waste generation rate by facility/student. The total waste generated was<br />
estimated to be 5.76 tons/day, of which 3.29 tons/day (57.2%) was GW, 0.15 tons/day (2.6%) was SR, and 2.33 tons/day (40.5%) was SFR. The authors also<br />
revealed a considerable potential to recycle and compost remaining in GW, at rates of 1.11 tons/day (19.3%) and 1.29 tons/day (22.4%), respectively. The<br />
total amount sent to a landfill could be reduced from 3.29 tons/day (57.2%) to 0.89 tons/day (15.5%). A detailed breakdown of the recycling and composting<br />
potential is also analyzed and discussed for use in policy making decisions. Through the Monte Carlo simulation, the 95% confidence interval of the total<br />
waste amount was estimated to be 4.85-7.71 tons/day.
