Design and construction of an automated garbage sorting, monitoring and compaction machine :

Abstract

Solid waste management is one of the primary problems that the world faces irrespective of the case of developed or developing countries (Maheshwaranetal., 2018). The central division of Kampala is concentrated with businesses and institutions that generate very high quantities of recyclable material, usually not sorted until it reaches a dumping site or sometimes sorted on the collection trucks by those who find value in it. This reduces the amount of waste from the division and the waste continues to reduce as more people get involved in waste picking. However, well-coordinated and managed efforts to increase the separation of wastes at the source would enhance the removal of recyclables, which would greatly reduce the waste destined for disposal (Aryampaet al.,2019). The idea to design and build an automatic waste sorting recycle bin is to support the initiative to separate different kind of trash according to specific categories at the early stage which is at domestic user such as at home and office. The mechanism adapted for compacting the waste is a scissor mechanism which is connected to a lead screw coupled to the DC gear motor, which is actuated by solar powered battery. By compacting, the volume of wastes in the container bin was reduced with a compaction ratio of 1.09 and 1.22 for plastic and paper respectively. The angle of inclination for the scissor mechanism is about 35° 50°to vertical axis for compacting the wastes inside the bin. This project uses a Wi-Fi module which alerts with a notification to the operator stating that the bin is filled when the volume of container bin reaches 100%.
