Adding alkaline metal oxides to boost the gasification reactions of sugarcane bagasse
Last Updated: junio 11, 2025This study explores a sustainable approach to mitigate the ongoing energy crisis and reducing fossil fuel dependency by focusing on biomass gasification and pyrolysis of sugarcane bagasse. The thermal degradation behavior of sugarcane bagasse was analyzed using thermogravimetric analysis (TGA), incorporating pure commercial compounds (Na₂O, MgO, CaO, KH₂PO₄) and dried vinasse (CzVz), a byproduct of ethanol distillation.
Bagasse-derived silver nanoparticles: antimicrobial and antibiofilm properties
Last Updated: junio 11, 2025Nanoparticles are less than 100 nm in size, and those made from metals such as silver have sparked considerable interest as ideal materials due to their unique features, such as biocompatibility, inert nature, stability, and low toxicity.
Characterizing sugarcane co-products and their biochars: effects on resulting properties and functionality
Last Updated: junio 9, 2025Solutions are needed for the utilization of both sugarcane bagasse and field residue as the largest sources by volume of fibrous co-products generated from harvesting and processing sugarcane. Successful conversion of these co-products into value-added materials requires full understanding of their properties and how they are affected by source, processing conditions and storage
Classifying lignocellulosic biomass from Tucumán for energy production
Last Updated: junio 9, 2025Classification of biomass is an important means to evaluate the properties of a fuel, as well as to infer its energy conversion potential. The aim of this study was to determine the classification of biomass with the highest energy potential in Tucumán, using the Van Krevelen diagram (H/C vs O/C) and the ternary diagram (C-H-O) methodology.
Culture medium design and kinetics of single-cell protein production from Candida utilis
Last Updated: junio 9, 2025The utilization of vinasse, a by-product of bioethanol production, as a substrate for single-cell protein (SCP) production is a sustainable solution to environmental challenges and protein demand. This study aimed to design a culture medium using vinasse and sugarcane molasses to optimize SCP production by Candida utilis yeast.
Effect of heating on color and fermentable sugars in final molasses
Last Updated: junio 9, 2025Increased levels of colorants (particularly the melanoidins) produced by decomposition of sugars in sugar boiling via the so called Maillard reaction, have a negative effect on sugar quality and recovery. Additionally, higher molasses color was reported to lead to lower yields in ethanol fermentation
Effect of molasses color on fermentation yield
Last Updated: junio 9, 2025Colorants and especially melanoidins, which are the products of Maillard reaction between reducing sugars and amino acids, are reported to affect sugarcane molasses fermentation and reduce ethanol yield. To quantify these effects, a batch micro-fermentation technique was adapted from the literature and used in a series of laboratory tests
Energy optimization in a sugar alcohol mill to maximize bagasse availability and electricity cogeneration: a case study at Incauca
Last Updated: junio 9, 2025Incauca, a leading company in the Colombian sugar-alcohol sector, has implemented an energy optimization project in its production plant with the objective of increasing the availability of bagasse for sale to the paper industry. The project was based on a review of the current state of the factory to identify opportunities for improvement
Gasification of harvest residues as a sustainable energy alternative in the sugarcane agroindustry of Tucumán, Argentina
Last Updated: junio 11, 2025In Tucumán, bioethanol is produced mainly from distilleries annexed to sugarcane plants that consume thermal and electrical energy supplied largely from the bagasse generated, which contributes to the sustainability of their process. However, additional fossil fuels are also used in the process to supply their energy requirements.
Green hydrogen – product diversification opportunities in sugar and allied industries – a techno-economic study
Last Updated: junio 9, 2025India uses about 6 Mt of hydrogen every year in industrial sectors, and this will rise to 28 Mt by 2050. To reduce its carbon emissions by 2050, India aims for 80% green hydrogen production to meet its total demand. Green hydrogen will have a significant share as a cleaner fuel in the energy requirement of India in addition to ethanol and bio-CNG in future.
