Abstract

The potential of yam peels for bioethanol production was investigated through an understanding of their compositional profile. The yam peels dried powder was subjected to X-ray diffraction analysis, and it was examined for proximate and biochemical composition. The result of the biochemical analysis of the yam peels showed the following: holocellulose (57.93 %) [cellulose (29.02 %) + hemicellulose (28.91 %)], and lignin (27.43 %), while the proximate analysis showed the following: moisture (11.11 %), ash (5.93 %), and volatile matter (68.4 %). Consequently, the X-ray diffraction pattern shows the presence of amorphous and crystalline region in the sample. The result showed that the yam peels possesses low lignin and high holocellulose content. This study indicate that the yam peels are potential candidates for bioethanol production.Â Â

Highlights

In a world that is threatened by climate change, instability in major oil-producing countries and rural economic decline, efforts to replace petroleum with alternative energy is gaining attention
Ash is the total content of dusts and inorganic substances in biomasses and it is estimated to be around 10 % in lignocellulose biomass (Yanqing et al, 2014)
The low ash content of the biomass waste further goes to confirm that the yam peels is good feedstock for bioethanol production

Summary

Introduction

In a world that is threatened by climate change, instability in major oil-producing countries and rural economic decline, efforts to replace petroleum with alternative energy is gaining attention. This has led to an increased interest in producing biofuels by utilizing agricultural crops, wastes and residues. Bioethanol as a locally produced fuel has the potential to improve trade balances in oil-importing nations, diversify energy portfolios, and lower dependence on foreign oil (Daniella, 2008). Rabah et al (2011) reported that bioethanol has the potential to diversify energy portfolios, lower dependence on foreign oil, and improve trade balances in oil-importing nations. The aim of this study is to investigate the potential of yam peels for bioethanol production through an understanding of their compositional profile
