The main energy supply in Ghana is based on biomass: firewood and charcoal (64%), which are burnt openly for cook and heat energy. This practice has led to deforestation and biomass shortage. Besides the energy challenge, Ghana faces declining of soil fertility due to continuous cultivation and rapid mineralization of its soil organic matter, both problems being considered as major causes of food insecurity and poverty in the country. We studied the carbonization of rice husks and corn stalks - the two main available sources of waste biomass in the studied regions - and qualifying these products as fuel and biochar. We pyrolysed both feedstocks at three different temperatures - 350, 450 and 550 °C - and measured their solid yields; ash and volatile contents; C, H, N percentages; pH and electro-conductivities and; nutrients contents in all samples. We also compared the thermogravimetric behavior and NMR profiles of these samples. Corn stalks showed better potential to be used as a fuel. Both feedstocks have potential to be used as biochar but with varied composition. |
