Sugarcane bagasse: a biomass sufficiently applied for improving global energy, environment and economic sustainability

Abstract

Sugarcane (Saccharum officinarum) bagasse (SCB) is a biomass of agricultural waste obtained from sugarcane processing that has been found in abundance globally. Due to its abundance in nature, researchers have been harnessing this biomass for numerous applications such as in energy and environmental sustainability. However, before it could be optimally utilised, it has to be pre-treated using available methods. Different pre-treatment methods were reviewed for SCB, both alkaline and alkali–acid process reveal efficient and successful approaches for obtaining higher glucose production from hydrolysis. Procedures for hydrolysis were evaluated, and results indicate that pre-treated SCB was susceptible to acid and enzymatic hydrolysis as > 80% glucose yield was obtained in both cases. The SCB could achieve a bio-ethanol (a biofuel) yield of > 0.2 g/g at optimal conditions and xylitol (a bio-product) yield at > 0.4 g/g in most cases. Thermochemical processing of SCB also gave excellent biofuel yields. The plethora of products obtained in this regard have been catalogued and elucidated extensively. As found in this study, the SCB could be used in diverse applications such as adsorbent, ion exchange resin, briquettes, ceramics, concrete, cement and polymer composites. Consequently, the SCB is a biomass with great potential to meet global energy demand and encourage environmental sustainability.

An overview of torrefied bioresource briquettes: quality-influencing parameters, enhancement through torrefaction and applications

“…Plant resources are the most abundant, promising, under-utilized, and cost-effective biological resources for fuel (Obi, 2015). Lignocellulosic biomass from plant resources could be converted to solid, liquid, or gaseous fuels through pyrolysis (Lee et al 2016), torrefaction (Wallace et al 2019;Waheed and Akogun, 2021), anaerobic digestion (Okuo et al 2016), hydrothermal carbonization (Xu et al 2018;Zhang et al 2021); fermentation (Sadh et al 2018), enzymatic hydrolysis (Chundawat et al 2011) densification (Ibitoye et al 2021), gasification and steam reforming (Ajala et al 2021), and transesterification reactions (Alamu et al 2008).…”

Sistemas de produção de cana-de-açúcar visando a produção de açúcar orgânico certificado

“…Possivelmente, esse gênero teve origem mesmo antes dos continentes apresentarem formas e localizações atuais, possuindo dois centros de diversidade, sendo estes o Velho e Novo Mundo (Cheavegatti-Gianotto et al, 2011). Do ponto de vista global para a produção dessa cultura, o Brasil vem se mostrando como o maior produtor de canade-açúcar, seguindo da Índia, China, Tailândia, Paquistão, México, Colômbia, Indonésia, Filipinas e Estados Unidos (Ajala et al, 2021).…”

Variabilidade temporal (2000 – 2020) da produção de cana-de-açúcar em Alagoa Nova, Brejo Paraibano

“…Atualmente a produção mundial de cana-deaçúcar supera a marca de 1,5 bilhões de toneladas anuais. Entre os maiores produtores dessa cultura figuram o Brasil, atualmente o maior produtor dessa cultura, a Índia, China, Tailândia, Paquistão, México, Colômbia, Indonésia, Filipinas e os Estados Unidos (Ajala et al, 2021). A cana-de-açúcar é cultivada em escala industrial para a produção de açúcar em mais de 90 países em todo o globo, tornando essa cultura responsável pela produção de cerca de 80% da produção mundial de açúcar (Pipitpukdee et al, 2020).…”
