“…Frame 1 briefly describes the cultures and their respective residues that originated bioproducts and bioinputs through the processes described in the publications. In these data, it is possible to observe the diversity of bioproducts generated by agro-industrial residues, such as levulinic acid (Abaide et al 2019), essential oils (Tavares et al 2020), xylose (Padilla-Rascón et al 2020), carrageenan (Solorzano-Chavez et al 2019, bio-oil (Casoni et al 2019), biosurfactant (Ni'Matuzahroh et al 2020) and lactic acid (Ahmad et al 2020) obtained from rice residues (straw), forest species (husk), olive (seed), sugarcane (bagasse), sunflower (seed husk), corn (cob) and grape (vinasse), respectively.…”

The expansion of agricultural production is increasingly accelerated, as a result of the greater need for food caused by population growth and, consequently, this growth results in the generation of greater amounts of waste. In general, the inspection of public environmental agencies and society demand from agribusinesses actions that increasingly seek the use of new environmental technologies for the destination of production residues, which can drastically reduce the impacts caused to the environment, in addition to add

“…It should be noted that this extract presents itself as a potential raw material for the manufacture of biofuels, where bioethanol is produced from the direct fermentation of simple sugars or after pretreatments of complex sugars followed by fermentation (Soccol et al, 2010;Zhang et al, 2020). Abaide et al (2019) and Vedovatto et al (2021) report obtaining fermentable sugars by-products through hydrolysis with subcritical water; however, although water is considered a green solvent, the use of this technology requires high pressures and high temperatures. Similarly, as the processes reported by Iwassa, Ribeiro, et al (2019) and Giombelli et al (2020) using subcritical water for sugar extraction.…”

In this study, different solid-liquid extraction conditions to obtain fermentable sugars from an asparagus by-product were investigated to produce a fiber concentrate.To evaluate the effects of agitation, solvent:sample ratio and temperature, an experimental design was used and the maximum extraction conditions of reducing sugars (RS) were determined. The diffusion coefficient of sugars in water at different temperatures was obtained, as well as the thermodynamic parameters of the process. The materials obtained before and after the extraction were characterized as composition, technological properties, and functional groups. The results showed that, under the conditions evaluated, agitation had the highest influence on the RS extraction, followed by the solvent:sample ratio and temperature. The maximum RS content (~30 g 100 g −1 dry asparagus by-product) was obtained at 125 rpm, 60°C,

“…According to Abaide et al (2019), the significant increase in energy and fuel demands coupled with a large amount of agricultural biomass produced worldwide provides an incentive to the development of research aimed at using lignocellulosic biomass as a source of bioproducts and renewable energy. Based on clean and sustainable technology, the hydrolysis with subcritical water is favorable for the dissociation of lignocellulosic biomass.…”

Subcritical water hydrolysis was used for the pre-treatment of residues generated in olive groves. Fermentable sugars were produced from the lignocellulosic material found in olive leaves and stems. Firstly, moisture, ash, particle average diameter, and total extracts were measured. Afterward, subcritical water hydrolysis was carried out at 20 MPa in a 50 mL reactor. The influences of two temperatures (180 and 220 °C) and two water flow rates (10 and 20 mL min-1) on the sugars yields were evaluated. The concentration of sugars was 31.3 g L-1 at 180 °C and 10 mL min-1 in a reaction for 3 min, of which glucose was the major sugar (27.64 g L-1). Statistical analysis was performed using Sisvar® 5.6 software and the averages were compared through Tukey’s test, considering a significance level of 95% (p<0.05). For the treatments evaluated in this work, only xylose was statistically different in the treatments with different water flow rates. The highest values of xylose were obtained with 10 mL min-1, which were 1.82 g L-1 (180 °C) and 2.18 g L-1 (220 °C). The total inhibitors were high at 220 °C for all water flow rates, with a significant difference from the averages obtained at 180 °C.
