“…Cellulosic biomass consists of cellulose, hemicellulose and lignin in varying proportions, depending on species. In the conventional interpretation of a forest biorefinery, cellulose and hemicellulose are converted to sugars, and further refined into a fuel, while (hydrolysis) lignin makes up the majority of the potential co‐product stream 9 . Pulp mills also produce a waste stream containing primarily lignin, which is most often combusted for process energy, in the case of Kraft mills, or sold as (low value) lignosulfonate, in the case of sulfite mills 10 .…”

A new forest biorefining model is emerging in which high‐value materials would be produced alongside a cellulosic sugar by‐product in facilities scaled to match fiber availability in northern forests. As these emerging biorefining technologies are being developed by private entities, the economics associated with them are little known. The goal of this study is to use publicly available information to carry out an initial techno‐economic assessment for two emerging biorefining technologies: one that produces sugar and hydrolysis lignin (H‐lignin) from thermomechanical pulping (TMP) and another that produces sugar, lignosulfonate, and nanocellulose. The break‐even price for H‐lignin and nanocellulose is estimated for the respective technology and a credit is applied for cellulosic sugar and other co‐product sales based on current market value. It was found that the minimum product selling price (MPSP) for H‐lignin was within the range of high purity lignin but not enough is known about the properties of H‐lignin to determine if this is a reasonable value for prospective end uses. The estimated MPSP of nanocellulose was found to be considerably lower than for more conventional nanocellulose‐producing methods that use Kraft or dissolving pulp as a starting point. The nanocellulose produced through the second process modeled has different properties than conventional nanocellulose, which need to be further explored. Having a sense of the cost to produce these novel materials will help to direct research on viable end uses. The methodology presented, using only publicly available information, can also be replicated for other emerging technologies. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…To optimize the use of raw biomass in biorefinery processes, it is essential to know and understand the physical aspects, as well as the chemical properties of biomass and its characteristics (RAMBO et al, 2015). Another crucial aspect is the choice of the most appropriate methodology or process for the release of carbohydrates present in each biomass, given that the decomposition of the polymers into their constituent monomer before conversion into value-added chemicals is a key step in this process, as each of the polymers has different degrees of recalcitrance for fractionation methods and different potential end products (AJAO et al, 2018).…”

The use of agro-industrial residues in biorefinery processes has been increasing due to the negative environmental impact associated with the excessive use of fossil fuels. Several residues have been evaluated as precursors for carbohydrate production, which in turn can be converted into numerous high value-added products, such as the products of the furanic series, 5-hydroxymethylfurfural and furfural. Thus, this work aimed to determine the chemical composition of passion fruit and purple yam peels in order to analyze their potential for use as raw material for biorefineries. For the determination of sugars, the shells were submitted to acid hydrolysis according to two different methodologies: one by the National Renewable Energy Laboratory method and the other by the Dunning et al. (1949) methodology. The products obtained were analyzed by Fourier Transform Infrared Spectrophotometry and High-Performance Liquid Chromatography. The results show that passion fruit and purple yam peels presented high percentages of hemicellulose (30% and 15%, respectively) and mainly of cellulose (above 44% for both shells according to the two tested methodologies). Due to the significant amount of these polysaccharides present in the biomass, they have potential for use in biorefineries.

“…Plant biomass is a viable alternative option for reducing the use of fossil fuels and its byproducts. Common sources of plant biomass include agroindustry wastes, natural fibers, forestry bioproducts, and crops (Yahya et al 2015;Dungani et al 2017;Ajao et al 2018). Agricultural residues are a renewable biomass which is a plentiful resource on earth (Das et al 2014;Poletto et al 2014).…”

Plant-derived biopolymers are renewable and readily available, thus making viable alternatives to synthetic polymers. The present study examined properties of biopolymers from cover crops such as rye, oat, clover, vetch, and barley, which were grown organically in a greenhouse. The yields of cellulose, hemicellulose, and lignin of the cover crops were calculated based on the dry weight. Structural variations and thermal properties of the isolated cellulose were characterized and compared with commercial cellulose using Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and Thermogravimetric analysis (TGA). The average yield percentages of cellulose, hemicellulose, and lignin were 19 to 27%, 9 to 25%, and 1.42 to 4.86%, respectively. The FTIR and Raman spectral analysis indicated that the isolated cellulose had similar peaks and patterns to commercial cellulose, and confirmed the removal of non-cellulosic constituents. The onset decomposition temperature occurred at 270 °C in all samples. Interestingly, the maximum degradation temperature beyond 370 °C in cellulose was isolated from black oat, which was higher than commercial cellulose (350 °C). The findings of this research suggest that cellulose isolated from cover crops may be a benefit to the polymer industry in the development of bio-based materials such as biofuels, bio-composites, and biomedical devices.
