Abstract
Initiatives within the framework of the circular economy stand out globally as alternatives with high potential to achieve sustainability. Strategies based on the production of microalgae as a low-cost biofeedstock in applications such as biofuels and food supplements are considered highly viable proposals in equatorial countries with high luminosity and warm weather. This research considers Ecuador as a case study. This work presents results in the production of ethanol from microalgae with thermal sterilization (121°C) for 15 minutes and without pretreatment of the algal biomass prior to enzymatic hydrolysis, in addition to assessing its possible sustainability. From the results, it stands out that there are no statistically significant differences in the ethanol yield, the biomass subjected to thermal sterilization presented an acid pH and lower reducing sugars, inferring that the biomass without pretreatment favors its use as animal feed.
