Evaluation of yield characteristics cum determinant factors in earth mound method of charcoal production using billet of Acacia nilotica

摘要

Tree residues are generated in large quantity in our environment. Nowadays, adding value to these residues could make them become item of economic importance. The aim of this study is to adapt a traditional method of charcoal production (Earth Mound) in order to add value to the tree residues generated in University of Ibadan with a view to enhance the benefit derived from them. The billets of Acacia nilotica were converted from both wet and dry wood samples. The billets were then grouped into six different parts. Moisture content to some extent has a great influence on the use of charcoal produced from traditional method as the billets of wood with a high moisture content of about 22.5% have the highest yield of 22kg of the total input of 9.83X10~(-4) m~3.
