Abstract
The purpose of this study is to identify the solid waste generation and compositions that are generated from UNIMAS West Campus area and also to calculate potential energy and profit that can be harvested from the solid waste. This study was conducted at UNIMAS west campus where the samples of solid waste were collected from different types of source of generation namely residential colleges, faculties, Centre Teaching Facilities (CTF) and cafeteria. The solid wastes collected are weighed, mixed, quartered and the compositions of the samples are determined. From the analysis, the solid waste generation rate is 499 kg per day and the major composition of solid waste produced from this study area is food waste with the value of 54% followed by plastic bottle with 9%, mixed plastic with 8%, mixed paper with 7%, box and polystyrene are with 5% and the less percentage of solid waste composition is aluminium with 4%. For the total estimation potential energy that generated by UNIMAS West Campus is about 12819.9 kJ/kg per day and the profit can be achieved when the solid wastes are recycles is about RM 126.43 per day. The analysis shows that solid waste generated in UNIMAS West Campus has a good potential in recycling and give more benefit to UNIMAS. With the data of the solid waste generated in this study area, proper management strategies can be planned by top management of UNIMAS and put it into action in the future. In long term, it will make UNIMAS a green campus which eventually reduces the amount of solid waste generation.
Highlights
Nowadays, the contributing factors towards the increasing Municipal Solid Waste Generation in Malaysia are almost similar to other developing countries
Food waste formed is the largest fraction of the solid waste with 54%, followed by plastic bottle with 9%, mixed plastic with 8%, mixed paper with 7%, box and polystyrene are with 5%, and the last percentage is 4% of solid waste composition is aluminum

Summary
The contributing factors towards the increasing Municipal Solid Waste Generation in Malaysia are almost similar to other developing countries. The amount of solid waste generation has been increased corresponding to the several factors such as rapid population growth, urbanization, income level and economic development. Those factors would accelerate the future of solid waste generation in developing countries [1]. The local authorities had been struggling to find alternative way for the waste disposal challenge management. These landfills have created various environmental problems such as flies production, bad odors and leachate that may cause negative effects such as the occurrence of diseases and groundwater pollution
