The chemical and energy valorization of organic waste is a challenge for the national sugar-energy sector. One way of using this type of waste is by producing renewable energy and chemicals with a low footprint of greenhouse gas emissions. Thus, the general objective of this proposal is to carry out integrated research for chemical and energy recovery of organic residues from the sugar-en…
Although the steps of the second generation ethanol (2G) production process are known and commercial plants begin to emerge in Brazil and worldwide, admittedly there are still bottlenecks that need to be improved to make ethanol 2G competitive. This project involves several theses addressing different stages of the process, always seeking to tackle the remaining bottlenecks.Pretreatment i…
Nowadays the raw material used for ethanol production is sugar cane sacarose. In Brazil, the availability of bagasse with low costs makes the development of technologies to hydrolyse this material and use it for the production of ethanol attractive, due to the possibility of integration with sugar plants and distilleries, using the existing infrastructure. If bagasse is used, a significan…

There is a great potential for the use of lignocellulosic biomass to produce chemicals and biofuels, such as ethanol. However, it remains a challenge to increase the biomass processing performance. Many steps need to be improved to achieve this goal, and one of them is thebiomass hydrolysis. In order to increase the competitive edge of the process, it's necessary to perform the hydrolysis…
Sugarcane bagasse is a lignocellulosic byproduct obtained from ethanol production (1G) and it's a promising substrate for second generation bioethanol production (2G). As hemicelluloses represents about 30% of bagasse dry weight, the amount of sugars generated after the hydrolysis of this material represents a substantial portion for the second generation bioethanol production. The yeast …
Sugars derived from lignocellulosic materials are the main raw material in bio-based process development for renewable fuels and chemicals. Although high biomass conversion yields can be achieved by enzymatic hydrolysis, this process presents some drawbacks that hinder its implementation on a commercial scale. High solid content in the hydrolysis (15-20% water-insoluble solids - WIS) is d…

Considering the process of ethanol production from lignocellulosic biomass (second-generation bioethanol), microorganisms that are naturally capable of converting pentoses into ethanol are desired, once fermentation with wild strains is simpler and cheaper than fermentation with transformed strains. In this scenario, two non-conventional yeasts have the potential for industrial applicatio…
Although not much explored, using protic ionic liquids (PIL's) might be an alternative to fractionate lignin from sugarcane bagasse and potentially change its ultrastructure. The vast majority of works in the literature use aprotic IL's, whose production is far more expensive than the protic ones. In this work, the pretreatment process with PIL will be evaluated. The Ph.D. project - on it…
One of the major drawbacks of enzymatic hydrolysis of lignocellulosic materials is the inhibition of enzymes by reaction products (cellobiose and glucose). This effect is even more pronounced in hydrolysis containing high solid content (15-20% or higher water-insoluble solids - WIS), which is desired in order to result in higher total reducing sugar concentration in hydrolysates and reduc…
