The limited supply of oil and the increasing need for energy make it necessary for alternative
energy sources based on biomass and environmentally friendly. One of them is by utilizing
hazelnut shell waste for feedstock energy alternatif.. The purpose of this study was to
determine the effect of the hazel shell delignification process on the levels of lignin,
cellulose, hemicellulose, to determine the effect of concentrations and alkali types to get the
optimization of lignin compound degradation. The method used is the delignification process …
