Considering sawdust as a potential raw material for climate change mitigation in indoor environment

Abstract

The object of the study is sawdust as a potential raw material for climate change mitigation in the indoor environment. The method of the mixture was used to determine the specific heat capacity of the sawdust sample, while its thermal conductivity was determined using the Lee disc method. The results of the study showed that the specific heat capacity of the sawdust is 54.9271 J·g–1·K–1 and that of thermal conductivity is 0.12 W/m·K. The implication of the results is that Sawdust needs about 54.9271 J·g–1·K–1 to raise its unit mass by 1 °C and a comparably very low thermal conductivity of 0.12 W/m·K. Sawdust can be used as a composite material for roofing, and ceilings to drastically reduce the rate at which the heat energy from the sun is transferred into the indoor environment and consequently reduce the effects of climate change on the indoor environment. Sawdust that is not properly managed or disposed can pose serious problems to aquatic and terrestrial ecosystems, fuel fire outbreaks and health problems such as severe allergic reactions. Therefore, discovering other reuse options for sawdust will reduce the problems it poses to the environment.
