COMPARISON OF BIOCHAR-COATED PLASTER AND BENTONITE PELLETS FOR CARBON DIOXIDE SEQUESTRATION

Abstract

Ever since it has been discovered that the world’s climate is drastically changing due to the effects of human activities, which have produced greenhouse gases, it has kickstarted many intiatives and projects to combat global warming. Biochar has been a topic of discussion as a mean to address these issues and it has been seen to be one of the more productive methods, which can sequester atmospheric carbon dioxide. Since globalization has taken place, human activity along with overpopulation around the globe has lead to problems with our Indoor Air Quality (IAQ). Biochar has been researched as a method to sequester carbon dioxide from the atmosphere both for indoor and outdoor uses. In this dissertation research paper, biochar would be used to explore its effectiveness in carbon capture in an indoor environment, specifically within a cavity wall. It explores the differences in using different materials for pellets, which will be coated with biochar. This strategy may provide a long-term solution for combating IAQ in hopes of turning a building into a carbon sink instead of a structure, which produces carbon dioxide. Different materials will be used to create pellets, which will be coated with biochar and inserted within a cavity wall. These experiments will then be subjected to high concentrations of carbon dioxide in an enclosed and tightly sealed setting. The results obtained from this experimental study will address the hypothesis of increasing carbon dioxide sequestration by biochar. The success of this dissertation paper would be able to increase the biochar’s potential in contribute to combat global warming.
