The production of biofuels is mainly based on the use of food as raw material, which generates a conflict when it comes to their use, since they generate cost overruns and can be used for human or animal consumption. In response to this, other alternatives are resorted to, being the cultivation of microalgae one of the most attractive; for being easy to cultivate, occupying less space than other types of crops and for its easy adaptation to environmental conditions. The development of this research aimed to address the feasibility of producing microalgae biomass, specifically Chlorella vulgaris, under natural environmental conditions using raceway type reactors. Two reactors were studied: bioreactor I and II, subjected to similar environmental conditions, and in both cases NPK 20 20 20 fertilizer was supplied. In both reactors, the parameters of ambient temperature, pH, dissolved oxygen, turbidity and light intensity were monitored, finding similar results for both reactors. For bioreactor I, biomass values of 646 mg/L were obtained and 16.35 mg of CO2/L was extracted from the environment, both on a daily basis, while for bioreactor II an average of 521 mg/L of biomass was obtained per day, and 14.95 mg of CO2/L of medium was extracted from the environment per day.
