“…In addition, the findings fall within the range of CV reported in literature for corn cob in South Africa (18. 02 MJ/kg) [26] and in other geographic zones such as Eastern Canada (18.75 MJ/ kg) [33] and South Asia (18.36 MJ/kg). [34] The results of the analysis of the raw biomass samples using ICP-MS and those of the elemental composition analysis of the ash obtained from the biomass samples using EDX are presented in Table 2 and Table 3, respectively.…”

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.

“…Among the broad variety of agricultural residues, maize cobs represent an interesting source of biomass, and their advantageous composition could allow their use for both direct combustion of dry biomass (Lizotte et al, 2015) and for the anaerobic fermentation process (Li et al, 2015).…”

Owing to the rising energy demand and the conflict between food, feed and energy crops for agricultural land, there is a growing need for alternative biomasses for energy purposes. New developments in harvesting technology have created the possibility of harvesting cobs as a by-product of maize grain harvesting. The aim of the present work has been to evaluate the potential and limitations of maize cob utilisation in an anaerobic digestion chain, considering the main agronomic, productive and qualitative traits. Maize grain and cob yields as well as the moisture content of samples collected from 1044 (farm) fields (located) in North West Italy have been determined over the 2012 growing season. Moreover, 27 representative fields were harvested using a modified combine-harvester that is able to collect maize grains and threshed cobs separately. The chemical composition and biochemical methane potential (BMP) of the cobs have been analysed.The relative potential yield of maize cobs was established as 18.7% of the grain mass, while the wet cob yield recorded in the field after mechanical harvesting was 1.6 t ha -1 . The total solid content was 60%. Fibre fractions represented over 85% of the dry cob matter, lignin content was about 16%, while the protein, ash, lipids and macro-elements (nitrogen, phosphorus, potassium) contents were very low compared to the whole-plant maize used for silage. The average BMP of wet threshed cob was 250±20 Nm 3 t VS -1 .Collected data have underlined that maize cobs could be used as a sustainable feedstock for anaerobic digestion processes.

“…Corn stalks have also been reported to be a good biomass energy source having a high heating value of 16-20 MJ/kg and an ash content of 5-21% depending on factors like moisture content, the period of harvest, variety, etc. [29][30][31][32][33][34]. The performance and properties of pellets are dependent on factors like compression methods [35][36][37], particle size [36,38], pellet die diameter [39,40], moisture content [36], chemical modification [41], mixture ratio [42], etc.…”

The quest for alternative energy sources is gradually shifting from natural fossil fuel to alternative bio-resources especially agricultural waste products due to their reduced pollution risk and sustainability. This study seeks to investigate the suitability of plant residue pellets to produce biomass. The plant residues investigated include; 100% granulated corn cob residues, 100% granulated corn stalks and a composite of 50:50 granulated corn cobs and stalk residues. The residues were compressed at 200 MPa and pelletized using cassava starch as a binder. The pellets were experimentally analyzed using emission, ultimate, proximate and calorimetry analyses. The result showed that the cobstalk 50:50 combination had the most desirable properties. It has 0.64% nitrogen, 48.57% carbon, 0.38% Sulphur, 6.22% hydrogen, 55.81% oxygen, 3.25% moisture content, 2.20% ash content, 80.0% volatile matter, 17.80% fixed carbon percentage, HHV of 32.9 kJ/kg, an average CO2 of 563±50 PPM, an average CO of 100±50 PPM, and an average value relative humidity of 69±4%. The study reiterates that corn residues are a good bio-fuel and should be encouraged to address the current energy shortfalls.
