Agroresidue-based biorefineries
Edgard Gnansounou, Binod Parameswaran
Agroresidues are the waste by-products of agricultural crops and agroindustries. The generation of these waste materials poses disposal issues that lead to environmental and economic concerns. These issues could be addressed by utilizing these waste materi ...
Elsevier2019Transition of a South African sugar mill towards a biorefinery. A feasibility assessment
Edgard Gnansounou, Jegannathan Kenthorai Raman, Elia Mercedes Ruiz Pachon, Pavel Vaskan
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 ...
ELSEVIER SCI LTD2018Reduction of process steam demand and water-usage through heat integration in sugar and ethanol production from sugarcane - Evaluation of different plant configurations
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 ...
2017Development of a novel ultrasound- assisted alkali pretreatment strategy for the production of bioethanol and xylanases from chili post harvest residue
A novel ultrasound-assisted alkali pretreatment strategy was developed which could effectively remove lignin and hemicelluloses and improve the sugar yield from chili post harvest residue. Operational parameters that affect the pretreatment efficiency were ...
Elsevier2017Environmental impact assessment of lignocellulosic lactic acid production: Integrated with existing sugar mills
Lactic acid (LA) is considered for the diversification and value addition to sugar industry in South Africa, through a bioconversion of sugarcane bagasse and leaves. A bioconversion process was modeled in Aspen Plus (R) V8.6 and its environmental impacts w ...
Institution of Chemical Engineers2016Development of a novel sequential pretreatment strategy for the production of bioethanol from sugarcane trash
Edgard Gnansounou, Binod Parameswaran
A novel sequential pretreatment strategy using biodiesel industry generated waste glycerol assisted transition metal and alkali pretreatment of sugarcane trash were developed for the production of bioethanol. Various process parameters affecting pretreatme ...
Elsevier2016Comparative techno-economic assessment and LCA of selected integrated sugarcane-based biorefineries
Edgard Gnansounou, Elia Mercedes Ruiz Pachon, Pavel Vaskan
This work addresses the economic and environmental performance of integrated biorefineries based on sugarcane juice and residues. Four multiproduct scenarios were considered; two from sugar mills and the others from ethanol distilleries. They are integrate ...
Elsevier2015Renewable and non-renewable exergy costs and CO2 emissions in the production of fuels for Brazilian transportation sector
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
2015Exergy and environmental comparison of the end use of vehicle fuels: The Brazilian case
In this work, a comparative exergy and environmental analysis of the vehicle fuel end use is presented. This analysis comprises petroleum and natural gas derivatives (including hydrogen), biofuels (ethanol and biodiesel), and their mixtures, besides of the ...
2015Sustainability assessment of lignocellulosic biorefineries under uncertainty
Biorefinery concepts refer to the integrated production of food, fuel, power, commodity chemicals, and polymers from biomass, mimicking the structure of a fossil-based refinery. The use of lignocellulosic biomass as feedstock for biorefineries has been pro ...
