Sugarcane straw as a potential second generation feedstock for biorefinery and white biotechnology applications

Brazilian Agro-industrial Wastes as Potential Textile and Other Raw Materials: a Sustainable Approach

“…Brazil tightly generates bioenergy and bioethanol from sugarcane. Studies show the growing and improvements in these processes, employing bagasse, straw, and fibers from the residual material (Aguiar et al 2021;Alarcon et al 2021;Barbosa et al 2020;Canilha et al 2012;Giese et al 2012;Soares et al 2020). In bagasse format, sugarcane presents a greater diversity of technology conversions for applicability for final use of cellulose nanocrystals (Fig.…”

Brazilian biorefineries from second generation biomass: critical insights from industry and future perspectives

“…Beta‐glucans have prebiotic properties and also act as immunomodulators. Lasiodiplodan is an emerging polysaccharide that can be produced by specific microorganisms thriving on cheap agro‐residues like corn meal, sugarcane bagasse, and rice bran in the fermentation process 3,5 . Pullulan is also a carbohydrate polymer consisting of maltotriose units linked through α‐1,4‐ and α‐1,6 glycosidic bonds.…”

“…These bioproducts have versatile commercial applications due to their inherent characteristics, biocompatibility, and biodegradability. Their production by microbial fermentation using cheap lignocellulosic sources can cater for the growing demand 2,3 . Brazil being a rich, agrarian country, which generates plentiful cheap lignocellulose feedstocks annually, is still lagging in the production and commercialization of these bio‐based products, which could diversify the biorefineries and promote the circular economy and the renewable economy.…”

“…The global demand for fuels is currently approximately 84 million barrels a day (16 million barrels less than in 2019 due to the impact of COVID‐19) and is projected to increase by 5.7 mb day –1 over the 2019–2025 period at an average annual rate of 950 kb day –1 1 . Due to the burgeoning demand for oil and chemicals, the oil price, and geopolitical factors, biomass valorization is an important issue that could significantly reduce the global dependence on fossil fuels 2,3 …”

Alterations in soil physical and hydraulic properties under sugarcane straw removal management: basis for assessment of ecosystem services related to water flow regulation and erosion control

“…In the Center-South region, which concentrates over 90% of total Brazilian production (CONAB, 2021), the burnt cane harvest system has been substituted by a system with mechanized harvesting of unburnt or "green" cane. In addition to the agronomic, environmental, and human health benefits, the transition to mechanized harvesting opened the possibility of using crop residues as raw material for cogeneration of electricity or production of cellulosic ethanol Carvalho et al, 2019 ;Aguiar et al, 2021), in addition to the already-used sugarcane bagasse. As the majority of sugarcane mills in the Center-South region are already energy-independent, and a growing number has been sending their surplus electricity to the national grid since 2013 (UNICA, 2020), the use of sugarcane straw to produce bioelectricity for commercialization is an interesting possibility to increase the financial sustainability of mills facing an economic crisis.…”
