Reducing solid waste generation is one of green campus achievement programs at University of Surabaya (Ubaya). It is important to quantify the amount and composition of solid waste generation of all the faculties because the data will determine the next step of solid waste management at Ubaya. The Faculty of Engineering significantly contributes to the amount of waste generation in Ubaya. A research related to Faculty of Engineering solid waste management needs to be conducted. The aims of the study were estimating the quantity of solid waste generation and observing the composition of solid waste in the Faculty of Engineering. The method of this research was survey of waste generation. The survey was conducted at classrooms and administrative office of the Faculty of Engineering . The estimation of waste generation was taken for 12 (twelve) days during April 2018. After collection, the waste materials were segregated into plastic bottle, plastic glass, plastic spoon, plastic straw, plastic packaging bag, food packaging, food waste, tissue, paper, and residue. The results of the research showed that the average daily solid waste generation faculty of engineering was to be 19.2 kgs. The solid waste composition was found to be plastic bottle 8.8% (1,7 kg/day), plastic glass 4.1 %(0,8 kg/day), plastic spoon 2% (0,4 kg/day), plastic straw 1% (0,2 kg/day), plastic packaging bag 9.9% (1.9 kg/day), food packaging 17.6% (3.4 kg/day), food waste 27%(5.2 kg/day), tissue 10.2% (2 kg/day), paper 9.8% (1.9 kg/day), and residue 9.6% (1.9 kg/day). The reducing potential of the waste was about 80%.
