Abstract

This report details the conception and design of a kitchen food waste composter to improve the kitchen food waste management in Malaysia. The current solid waste management system in which most of the waste generated goes to landfills is non-environmentally friendly and is inadequate to handle the drastic increase in the food waste generation. Therefore, the aims of this report are to conceptually design a kitchen food waste composter using theoretical formula, to model the kitchen food waste composter using CATIA software and to perform finite element analysis on the designed kitchen food waste composter. Research are carried out on developing operating conditions such as composting temperature and capacity for an ideal composting process as well as determining suitable operating mechanisms for maximum performance of the kitchen food waste composter. A kitchen food waste composter is formed with major working mechanisms which includes shredding and composting processes with automated interval mixing mechanism. The morphological chart and PUGH method are implemented for design generation and evaluation of the kitchen food waste composter. The positive outcome of this report is recommended to be applied in Malaysia as an alternative for handling food waste at household level and reducing the impact of food waste to the environment.
