I. Introduction
Since the human being lived in this world, different kinds of waste were produced continuously. In the early years, the common wastes produced were biodegradable. There are no major problems with this since it will decompose over time. As the number of population increases and new inventions were made, the kind of waste produced by humans also increases. Some of these wastes include plastics, glass, metal, papers and many more. Some of waste scattered in the surroundings are recyclable. But due to improper waste management, these are not optimized.
In the current generation, different manual systems are starting to be automated. Waste management was also starting to follow the trend. In other countries, there are automated

Whereas the crude methods of sorting wastes practiced may be efficient, it wastes useful time; hence the need for a mechanized sorting machine. An attempt has been made to develop a waste sorting machine, which is conceptualized to sort wastes into light materials, ferrous metals and other heavy materials. The waste sorting machine consists of a hopper through which the waste is fed through; a fan and air channel through which the light weight materials are separated from the waste matrix; a belt conveyor which carries the left waste towards a magnet-fitted shaft/pulley which separates ferrous metals and also chambers into which the separated components of the waste fall. The machine is designed with the major components being the fan, the belt conveyor and the magnet. Tests carried out on the machine successfully classified wastes into light materials and heavy materials with inability to sort ferrous metals. Samples of wastes tested weighed 1.15kg and 3.53kg. The wastes consisted of an average of 32% of light materials and the time to sort the waste was 65 minutes per unit mass. This machine separates light materials such as paper, nylon, textile and heavy materials similar to nylon, ferrous and non ferrous metal, glass and paper sorted by the machine developed by Falayi in the tear 2007 and the machine designed by Adzimah and Anthony
