Abstract:
Waste lignocellulosic biomass and biomass-derived materials, like paper wastes have been widely studied as a resource for bio-ethanol production. Accurate knowledge of composition (newspaper, cardboard, magazine and office paper in this study) is a key to determine their potential processability and suitability for ethanol production. The widely used two-step extraction method and acid soluble lignin measurement developed by National Renewable Energy Laboratory were applied to waste paper materials in this study. The effect of extractives on carbohydrates and lignin determinations were investigated. It was concluded that the extraction is routinely necessary before acid hydrolysed carbohydrate analysis. Furthermore, the wavelength of 320 nm and corresponding absorptivity constants for four types of paper wastes were determined for acid soluble lignin measurement. Based on this, complete compositional analyses for the four paper materials were carried out and good mass closure was achieved. This paper provides a guide for developing compositional analysis for novel biomass sources and a basis for their enzymatic hydrolysis in the future work.
