“…Por outro lado, China, Tailândiae Índia, continuam a investir progressivamente na biotecnologia agrícola e surgem como potenciais produtores de biocombustíveis. [29][30][31] Embora o bioetanol se apresente como uma alternativa promissora para substituir os derivados do petróleo. A sua produção à base de açúcar ou milho não é suficiente para atender a demanda atual de combustíveis fósseis.…”

The dependence on oil and other fossil resources raises global concerns and questions, as they are not considered sustainable from an economic and environmental point of view. The excess availability of residual agricultural material, the growing need for energy in the transport sector and the environmental benefit, due to the possible reduction of greenhouse gases, have boosted the development of liquid biofuels, including second generation bioethanol. Bioethanol is produced by hydrolysis of lignocellulosic materials, to obtain sugars that are later converted into alcohol by fermentation. This process involves the stages of pre-treatment of biomass, saccharification of cellulose, fermentation of hydrolyzate and distillation of alcohol. This work presents and discusses the different technological routes for cellulose hydrolysis, exposing the contrasts between enzymatic hydrolysis and acid hydrolysis, covering parameters such as reaction conditions, cost, yield and applicability. Showing that enzymatic hydrolysis, in general, is superior to homogeneous acid hydrolysis, however, heterogeneous acid hydrolysis presents itself as the most promising hydrolysis route to reduce the weak points found in the production process of this biofuel.A dependência do petróleo e dos demais recursos fósseis gera preocupações e questionamentos globais, em função dos mesmos não serem considerados sustentáveis no ponto de vista econômico e ambiental. A grande disponibilidade de material residual agrícola, a crescente necessidade de energia no setor dos transportes e o benefício ambiental, em função da possível redução dos gases de efeito estufa, impulsionaram o desenvolvimento de biocombustíveis líquidos, entre eles o bioetanol de segunda geração. O bioetanol é produzido a partir da hidrólise de materiais lignocelulósicos, na qual são obtidos açúcares que, posteriormente, são convertidos em álcool por fermentação. Esse processo envolve as etapas de prétratamento da biomassa, a sacarificação da celulose, fermentação do hidrolisado e a destilação do álcool. Esse trabalho apresenta e discute as diferentes rotas tecnológicas para a hidrólise da celulose, expondo os contrastes entre a hidrólise enzimática e a realizada por via ácida, abrangendo parâmetros como, condições reacionais, custo, rendimento e aplicabilidade. Fica evidenciado que a hidrólise enzimática, de forma geral, é mais vantajosa que a hidrólise ácida homogênea. Porém, a hidrólise ácida heterogênea se apresenta como a mais promissora rota com perspectivas de reduzir os pontos fracos existentes no processo produtivo desse biocombustível.

“…More recent research has also explored other possible feedstocks - Byadgi and Kalburgi (2016) considered the use of waste newspapers due to lower feedstock costs and to minimise the newspaper load on municipal waste. Others include bioethanol production form waste potatoes and waste money bills (Sheikh et al, 2013;Ali & Jiyad, 2015) However, there are four major sources of agrowaste that are widely studied and are most favourable due to their abundant availability. These sources are rice straw, wheat straw, corn straw and bagasse (the dry pulpy residue left after the extraction of juice from sugar cane).…”

This chapter discusses alternative energy sources and the advantages of biofuels over fossil fuels. It outlines the main steps of bioethanol production and suggests some alternative sources as potential feedstock. The core focus of this chapter is to examine new research which considers the use of agricultural waste as a feedstock for bioethanol production rather than conventional feedstocks such as sugarcane and corn. The advantages of sugarcane bagasse as a feedstock are discussed in detail and the bioprocessing requirements are studied in comparison to traditional methods that use sugarcane as the feedstock. The chapter concludes by briefly outlining further research that could potentially improve these processes.

“…Bioenergy, derived from biomass [1,2], municipal organic solid waste [3], livestock manure [4], and other biological materials [5][6][7], has been seen increasingly as a renewable and clean energy source. Among all utilization methods in bioenergy research (such as direct combustion, thermo-chemical conversation and biological conversion technologies) fast pyrolysis-a rapid decomposition of organic materials in the absence of oxygen-has many advantages.…”
