The sugarcane sector in Brazil has undergone a major modernization in the last thirty years. Embracing the biorefinery concept, this sector is investigating bioproduct diversification and mostly putting a lot of effort and investment on second generation e ...
The survival of the sugar industry in South Africa is under threat due to an unstable and low sugar price, high production cost and old infrastructure. At present, coal and sugarcane bagasse are used as fuels in an inefficient boiler to generate the heat a ...
The sugarcane industry represents one of the most important economic activities in Brazil producing sugar and ethanol for the internal and external markets. There are also plants dedicated only to ethanol production. The aim of this study is to accomplish ...
Lignocellulose-based biofuels are of major importance to mitigate the impact of international traffic and transport on climate change while sustaining agricultural land for food supply. Highly integrated systems like consolidated bioprocessing (CBP), where ...
First generation ethanol (1G) contributes to the majority of the ethanol produced worldwide, predominantly centered on corn and sugarcane. Nevertheless, several issues are regularly highlighted concerning the long-term sustainability of this technology, in ...
This article applies a systematic methodology to the optimization and comparison of two sugarcane conversion processes of great potential: the production of first generation ethanol and electricity in an integrated distillery and cogeneration plant (1G+COG ...
The goal of this paper is to evaluate the supply of sugarcane to mills and also the supply of green harvesting residues to second-generation ethanol plants under three different strategies: chopping, baling and integral harvesting. A dynamic model was deve ...
This work focuses on the revamp of existing sugarcane biorefineries and cogeneration units by using those byproducts, aiming to increase the selling of surplus electricity. The analysis allows identifying potential improvements in the sugarcane cogeneratio ...
Currently, electricity generation and second-generation ethanol production from lignocellulosic feedstocks represent technological alternatives in the bioenergy sector. Nevertheless, the introduction of new production processes denotes a real challenge due ...
The aim of the present study was to investigate the combination of steam pretreatment and biological treatment with lignin degrading fungal strains in order to enable efficient bioprocessing of beech wood to ethanol. In a sequential process of steam and fu ...
