“…Bagasse and molasses are wastes generated from the sugar industry. They are used in electricity generation, paper production, bioethanol production, and as animal feed . Bagasse is a fibrous residue produced from sugarcane processing after the juice must have been extracted from the sugar‐cane stalks .…”

“…The bagasse, like most other biomass, is composed mainly of lignin, cellulose, and hemicellulose, and therefore fits in as a perfect source of raw material for second‐generation bioethanol production . Sugarcane bagasse has a high calorific value and, as such, it is very attractive for energy production . About 5% of the entire sugarcane produced globally is from Africa and countries in sub‐Saharan Africa generate about 30% of the sugarcane produced in Africa.…”

“…Africa's largest corn producer is South Africa, with corn production reaching about 14.9 MMT in 2013 and 11.3 MMT in 2014. The agricultural sector in South Africa generates the highest biomass from corn plantations, which spans over an area of 3 million ha out of about 14.7 million ha of arable land available in the country . Nigeria is recognized as the tenth largest corn producer in the world and a major producer of the crop in Africa.…”

“…Disposing of the residues (cobs) of corn can pose serious environmental issues in countries like South Africa and Nigeria where corn is produced in large quantities. There is currently a dearth of information on the use of corn cobs biomass for bioethanol production in Nigeria, despite the fact that corncobs are produced in huge amounts there annually . Corn residues consisting of the stalks and cobs serves as raw materials for energy generation in some countries.…”

The need to diversify energy sources and to change from the present non‐renewable hydrocarbon sources to renewable energy sources has prompted huge investments in research activities to produce bioethanol from carbohydrate‐rich foodstuffs such as cassava tuber, sugarcane molasses, yam tubers, rice grains, corn grains, and a host of others. In recent times, however, more attention has been given to producing bioethanol from the non‐edible parts of carbohydrate‐rich foodstuffs, which are obtained mainly as waste products from food‐crop processing. Such non‐edible components include peels, bagasse, straw, stalk, and cobs. The most important component of the biomass is lignocellulose, which is broken down into carbohydrates and then fermented. The major challenge in deploying biomass as feedstock for bioethanol production is the fact that lignocellulosic biomass is highly recalcitrant and therefore requires more vigorous pretreatment prior to saccharification and fermentation. The main techniques used for pretreating lignocellulosic materials are physical and thermal as well as chemical and biological methods. In Nigeria, lignocellulosic bioethanol production potential from agricultural residues amounts to about 7.556 × 109 L per annum with more than 62% generated from process residues. Cassava biomass alone can produce more than 114 L of bioethanol for every ton of cassava peels after processing. Nigeria has more than enough agricultural residues for bioethanol production to meet its sustainable bioethanol‐blending demands. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

Biocompositional and thermodecompositional analyses of locally abundant agro‐wastes of South African corn were evaluated for their potential utilization as biocommodities via thermochemical and bioconversion processing. Corncob of Zea mays Zama star (white) & PAN 6Q‐252 (yellow) hybrid as well as the ear husks of South African sweet corn, Z. mays var. Saccharata were utilized in the beneficiation process. Proximate and elemental analyses were conducted to check for the moisture content, the ash content, the volatile matter, and the elemental composition of the agro‐waste samples. In addition, the thermal property of the waste, the surface chemistry and the calorific values were investigated using thermogravimetric analysis, Fourier‐transform infrared (FTIR) spectroscopy and bomb calorimetric technique, respectively. Significant amounts of alkali metals (Li, Na, and K) were found in the corn cob samples, and heavy metals such as thorium and uranium were detected in the ear husks, indicating that the biomass might not be suitable for use in thermochemical process. However, a relatively high volatile matter content recorded for the waste samples supports their use in thermochemical process with improved yield per gram of feed. These and other findings such as the high calorific value of the cob samples and the relatively low lignin‐to‐sugar ratio of the waste confirm previous reports regarding their suitability as feedstocks in thermo‐processing and bioprocessing. With the exception of the moisture content in ear husks, the minimal variation in the physicochemical property of the waste samples substantiates their suitability for co‐processing without major upsets in process kinetics. Results of other investigations such as the thermodecompositional behavior of the waste samples and the surface chemistry further shed light on the physicochemical property of the locally sourced lignocellulosic biomass waste samples. © 2017 Curtin University and John Wiley & Sons, Ltd.
