The need to improve the sustainability of bioethanol production from sugarcane in Brazil has intensified the search for process energy optimization coupled with the environmental suitability of the generated coproducts and wastes. In this scenario, the anaerobic digestion of vinasse (the most...

Sugarcane trash and bagasse, lignocellulosic materials obtained during sugarcane harvesting and processing, may be used as fuels for electricity production and/or as feedstock for second generation ethanol. If electricity prices are favorable, more lignocellulosic material may be diverted for...

Sugarcane ethanol biorefineries in Brazil produce carbon dioxide, electricity and heat as byproducts. These are essential inputs for algae biodiesel production. In this paper, we assessed ethanol's life cycle greenhouse gas emissions and fossil energy use produced in an integrated sugarcane and...

Sugarcane bagasse and trash may be used as feedstock for second generation ethanol production. Production of second generation ethanol integrated with first generation plants processing sugarcane presents several advantages over the stand-alone second generation ethanol production process;...

This work compares the technical, economic and environmental (GHG emissions mitigation) performance of power generation and ethanol production from sugarcane residual biomass, considering conversion plants adjacent to a sugarcane mill in Brazil. Systems performances were simulated for a...

The biorefinery of the future will be an integrated complex that makes a variety of products (e.g., biofuels, chemicals, power and protein) from a variety of feedstocks. The objective of this work was to evaluate the environmental benefits, compared to the traditional sugarcane ethanol system,...

The replacement of fossil fuels by biofuels has been extremely important worldwide to stimulate the growth of economies based on the sustainability through the use of renewable resources. Anaerobic digestion for biogas production is recognized as a clean technology that allies the suitability of...
