Thermal properties of bio-insulation made from waste

The dramatic growth of the tourism in Sagarmantha National Park and Buffer Zone has brought the construction of large number of modern building using imported construction materials. Moreover, with the growing tourism industry in the Park, increasing non-renewable solid waste has exacerbated the problem in the Park. Therefore, this research focuses on reusing the waste product such as paper, plastics, wooden grain to make the bio-insulation. The cold weather in the high altitude regions demands high amount of energy for room heating. If the buildings were poorly insulated, a great deal of heat will escape aggravating already poor supply of energy. In order to reduce the amount of energy wastage, there is a need to insulate the buildings properly. The bio-insulation tile made up of locally available material like white soil (Kamero), cow dung and waste product like paper, plastic, wooden grain were tested in two different methods;thermo-Box method and Lee’s method. Their thermal conductivity and transmittance were measured and a comparison was done. This paper mainly deals the efficiency of insulation tiles as well as the method used.
