Abstract: The application of biochar as part of landfill soil cover to adsorb and store carbon dioxide to mitigate its effects on global warming has been extensively studied. More studies are needed to investigate the similar application of biochar for the adsorption and storage of methane. This study aims to evaluate the capability of sheep wool biochar, prepared at different temperatures, at adsorbing and storing methane gas. This will be done using two methods – a fourier-transform infrared spectroscopy test, to determine the functional groups on the surface of the biochar and the pattern of adsorption and desorption of methane, and a gas chromatography-mass spectrometry test to determine the rate of desorption of methane from the biochar at increasing temperatures. The results of the tests were qualitative but show that sheep wool biochar can adsorb methane. However, it is not able to efficiently store methane as it quickly desorbs over a short span of time and with an increase in temperature. A comparison with plant-based biochar shows that sheep wool biochar has little potential as an efficient biochar to adsorb and store methane. Further studies could be conducted to quantify the capability of sheep wool biochar at adsorbing and storing methane.
