Sorting and miniaturization of household waste

Abstract

Waste sorting and miniaturization is an important step in waste management and recycling, since it allows the recovery of a decent percentage of the resources contained in the disposed waste. The aim of this study is to implement this procedure at small-scale levels such as households or municipalities. In this context, a waste sorting and miniaturizing unit is proposed consisting of two miniaturizing techniques: a ball grinder for turning glass into cullet and a shaft compactor for miniaturizing metals, plastics and paper. The design is established following a series of drop tests and compression tests on various types of waste. It could be easily scaled to bigger sizes such as municipal level. The implementation of this concept at small-scale levels will help in spreading environmental awareness, involving individuals in waste management, and inciting municipalities to host waste treatment facilities. All this will help build a more "Green" society.
