CARBON DIOXIDE ABSORPTION CAPABILITY OF BIOCHAR DERIVED FROM COCONUT HUSK

Abstract

The use of biochar as additive for improvements of soil quality and climate mitigation has gained greater relevance in today’s context and this can be attributed to biochar’s capabilities in carbon dioxide adsorption. This dissertation aims to determine the optimum conditions for the production of coconut husk biochar through the analysis of the achieved yield rate. An in-depth analysis of the coconut husk biochar produced at different temperatures will be conducted, where data will be analysed from four different types of laboratory tests. The results showed that the reduction in mass for biochar production is lower when conducted at higher temperatures, where the optimal conditions for producing biochar is at 500 degrees celcius with a heating rate of 10 degrees celcius/min. From the results of the four laboratory experiments, it is concluded that the coconut husk biochar produced at 500 degrees celcius has a higher carbon dioxide adsorption capability as compared to the coconut husk biochar produced at 300 degrees celcius. This can be attributed to the increased porosity when producing biochar at higher temperatures.
