“…Lignin‐to‐saccharide ratio obtained in this study was in ascending order: CCR < CCW < CCH (0.0784, 0.123, and 0.2366, respectively). Danish et al ., reported 37.52 wt.%, 47.47 wt.%, and 6.85 wt.% of cellulose, hemicellulose, and lignin in corn cob samples sourced from Southern Asia . High compositions of sugar polymers in biomass are directly correlated to increased quantity of bio‐based products obtainable from raw feeds depending on the efficiency of pre‐treatment and fermentation systems .…”

“…The results as documented and the implications for respective biomass quality was described in terms of their efficient use as feedstocks in advanced biomass processing platforms. The major polymeric constituents – cellulose, hemicellulose, and lignin of the waste samples – were quantified and found to be in the same range as reported for corn cobs from other geographical locations . High hemicellulose contents and lignin composition as low as 7 wt.% (as observed for the cob waste materials) make them ideal (upon pre‐treatment) for application in consolidated biomass conversions processes.…”

[36] High hemicellulose contents and lignin composition as low as 7 wt.% (as observed for the cob waste materials) make them ideal (upon pre-treatment) for application in consolidated biomass conversions processes. The presence of heavy metals such as thorium and uranium, although in trace amounts in the ear husks, for example, CCH, indicates that the waste will require a pre-treatment step using separation techniques like filtration or magnetization to remove the heavy metals before it could be utilized in bioconversion.…”

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.

“…Rice husk is a highly produced agricultural biomass in areas like India, Malaysia, China, Pakistan, and Brunei that are rich in rice production. [5][6][7] Rice production in Malaysia is about 0.7% of the total biomass production, of which paddy residue production has increased up to 7 million tons per year by 2020 so it can be used for as a source of bio-oil. 7,8 Table 1 shows few latest studies on physiochemical characteristics (dry, ash-free basis) of rice husk in the developing countries including South Asian region.…”

Summary Research on utilization of abundant rice residue for valuable bioenergy products is still not explored completely. A simple, robust, cheap, and one‐step fast pyrolysis reactor is still a key demand for production of bioenergy products, ie, high quality bio‐oil and biochar. Bio‐oil extracted from fast pyrolysis does not have adequate quality (eg, acidic and highly oxygenated). Catalytic fast pyrolysis using zeolites in the fast pyrolysis process effectively reduces the oxygen content (no H2 required). In this paper, the zeolites with different pore sizes and shapes (small pore, SAPO‐34 (0.56) and ferrierite (30); medium pore, ZSM‐5 (30), MCM‐22 (30), and ITQ‐2 (30); and large pore zeolite, mordenite (30)) were tested in a drop‐type fixed‐bed pyrolyzer. Catalytic deoxygenation is conducted at 450°C at the catalyst/biomass ratio of 0.1. Zeolite catalysts, its pore size and shape, could influence largely on deoxygenation. It was found that the small pore zeolites did not produce aromatics as compared to higher amount of aromatics formed in case of medium pore zeolites. ZSM‐5 and ITQ‐2 zeolites were especially efficient for the higher deoxygenation of biomass pyrolysis vapors due to better pore dimension and higher acidity.

Membrane technology remains the most energy‐efficient process for removing contaminants (micrometer‐size particles to angstrom‐size hydrated ions) from water. However, the current membrane technology, involving relatively expensive synthetic materials, is often nonsustainable for the poorest communities in the society. In this article, perspectives are provided on the emerging nanocellulose‐enabled membrane technology based on nanoscale cellulose fibers that can be extracted from almost any biomass. It is conceivable that nanocellulose membranes developed from inexpensive, abundant, and sustainable resources (such as agriculture residues and underutilized biomass waste) can lower the cost of membrane separation, as these membranes offer the ability to remove a range of pollutants in one step, via size exclusion and/or adsorption. The nanocellulose‐enabled membrane technology not only may be suitable for tackling global drinking water challenges, but it can also provide a new low‐cost platform for various pressure‐driven filtration techniques, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Some relevant parameters that can control the filtration performance of nanocellulose‐enabled membranes are comprehensively discussed. A short review of the current state of development for nanocellulose membranes is also provided.
