Generation and Composition of Solid Waste in University Campus

Abstract

Solid waste generation and composition analysis is a critical first step towards developing successful and effective planning of waste management service and strategies across university campus. This paper will present findings of solid waste study in UiTM (Perak). The objective of the study was to identify types, quantity and composition of solid waste in hostel area. A waste audit was conducted at 4 hostels blocks to estimate the quantity of waste generated. A total of 8 bins were selected for waste sampling for duration of 6 days for each block. Waste from every sample had been sorted manually and weighed. All the data had been recorded according to the waste categories in a standard form. The total waste collected at the hostel blocks was 1,660kg/day. Based on the hostel occupancy of 3498 students at the time of the study, the waste generation rate per students was estimated as 0.47kg/day. The types of solid waste collected were paper, aluminum, glass, plastic, food waste, e-waste, clinical waste and others. The highest composition was food waste accounted for 48.30% by weight. Meanwhile the lowest composition was clinical waste with the percentage of 0.64%. Based on this data, the quantity of solid waste in this hostel area was estimated at 605,900 kg a year. Currently solid waste collection and disposal in UiTM (Perak) are managed by Department of Facilities Management through two appointed contractors. All the collected solid waste is sent to the municipal dumpsite for final disposal. In conclusion the characterization of solid waste in UiTM (Perak) provides better understanding of waste profile. This can facilitate the provision of better waste management system which emphasize on the minimizing and recycling of waste.
