“…It is similar to the one, which occurred in the sugarcane production chain, where initially when its bagasse had no economic value as a valued co-product. A crop residue value chain similar to the one suggested by Gondwe et al (2017) can be considered as an initial proposition for future research, based on the results obtained here. The typical costs of corn crop (ARTUZO et al, 2018), mainly the ones represented by machine operation -as for corn processing and storage -can be mitigated with the commercialization of an addedvalue co-product as husk leaf and cob.…”

After harvest, usually a significant amount of crop residues are available and part of it can be a feedstock for biomass energy. This paper´s objective is to quantify sustainable residual biomass from corn harvesting, husk leaf, and cob, and its solid-fuel characterization for energy co-generation assessment. The methodology considers geographical distributions of corn production on a municipal basis, at Mato Grosso do Sul (MS) State in Brazil. Residual biomass from corn harvest has its mass fractions and energy characteristics determined via proximate and ultimate analyzes, bulk density, and heating values. Also, assessment of energy and power obtained by using co-generation power plants technology. The conclusions identify that residual biomass from corn harvest (husk leaf and cob) have large amounts available for energy use (~190.106 kg), and a main one geographic micro-region at MS. Its characteristics as solid fuel, i.e., HHV~18 MJ.kg-1 and TMC,db

“…Numerous forms of biomass have been exploited as energy sources; some of which include; wood shavings/saw dust, agricultural wastes, forest product processing waste, etc. Presently the agricultural residues are receiving serious attention based on the current studies in this area [6,10,[11][12][13][14][15][16][17]. In Nigeria, biomass is mostly obtained from agricultural crop residues and waste generated from the production and processing of corn, sugarcane, rice, forestry residues, cassava, palm kernel, coconut 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.
