Design, Analysis and Fabrication of Semi-automatic Trash Masher

Abstract

In this era of industrialisation, commercial building insulation is important so as to attain greater energy efficiency and meeting occupant comfort. The conventional insulating material such as Plaster of Paris or thermocol has their own environmental impacts. Thermocol as a solid waste does not decompose in the soil and hence makes the soil infertile. Also Plaster of Paris oxidises at high temperature to form toxic oxides of sulphur. This makes the use of a safe, non-hazardous eco-friendly insulating material, a necessity. This paper discusses the design, analysis and fabrication of a semi-automatic trash masher which compresses eco-friendly waste materials with the help of a double-acting hydraulic cylinder setup and makes it to take the form of a slab. This slab can then be used as a false ceiling material for insulating air-conditioned room or for interior decoration purposes. Rice husk ash has been proved to have good thermal insulating property. By making use of this unique property of rice husk ash, it can be converted into ceiling boards along with naturally available binding materials such as bee wax in a semi-automatic trash masher, thus promoting an eco-friendly move.
