Corncobs are a plentiful lignocellulosic material that can be utilized for energy production as well as the generation of other high-value products. Within the modern concept of biorefineries, we present processes conducted in a column reactor for the valorization of corncobs as a substrate for ethanol and xylitol production. In the first step, corncobs were subjected to acid hydrolysis, resulting in a hemicellulosic hydrolysate rich in xylose sugars intended for xylitol production by Candida tropicalis UFMGBX12-a. The YP/S (yield coefficient of product to substrate) and QP (productivity) values were approximately 0.2 g/g and 0.15 g/L·h, respectively, for the assays conducted in the column reactor. Next, the remaining solid portion of cellulignin was used for ethanol production through semi-simultaneous saccharification and fermentation process by Scheffersomyces parashehatae UFMG-HM 52.2. This approach involved an intensified successive process consisting of alkaline pretreatment of cellulignin, followed by enzymatic hydrolysis and fermentative processes conducted in the same reactor without biomass transfer. After obtaining the enzymatic hydrolysate, a QP value of 0.4 g/L·h for ethanol production was observed in the fermentation process conducted in the column reactor. The results demonstrate the potential of corncobs as a carbon source for biomolecules production, utilizing a process conducive to scale-up.

Coconut shells and cassava peels are agricultural residues that are abundantly produced in places where coconut and cassava processing activities are prevalent. formerly these waste products have been disposed of through incineration or natural decomposition, hence exacerbating air pollution and triggering degradation of the environment. The objective of this research is to determine the optimum combination of mixed mass fraction and drying temperature for briquettes produced from coconut shell and cassava peel. Observed variable on this research was Mass fraction with the ratio of coconut shell and Cassava peel 75:25 as level 1, 70:30 as level 2 and 65:35 as level 3. Drying temperature has 3 level 150oC, 200oC and 250oC. The lowest calorific value achieved in briquette made of 65% coconut shell mix with 35% Cassava peel and drying temperature is 200oC on second replication The highest calorific value achieved in briquette made of 65% coconut shell mix with 35% Cassava peel and drying temperature is 150oC on third replication. Coconut shell has a greater effect than Cassava peel on the calorific value of briquettes, but the chemical content of Cassava peel makes the burning rate longer. According to the outcomes of the normality test, versus fits, histograms, and versus order plots indicate that the data has a normal distribution. based on optimization results using Taguchi L9 and ANOVA optimizer the optimal combination using rule larger better is the mass fraction of coconut shell 70:30 Cassava peel with a drying temperature of 250oC.
