In order to level the ratio of organic matter and water, within the biodigestion process it is necessary to crush the organic waste, to facilitate its decomposition, once the reactor is filled, it is hermetically sealed to obtain biogas. As a complement to the biodigester prototype, a desktop application was developed to speed up the biodigester calculations, facilitating the obtaining of data referring to the approximate amounts of methane gas produced by a specific amount of organic matter with its properties. Developing: The project is developed in two phases: 1.- Investigate and characterize the organic waste generated in the UTSOE, for the filling of a biodigester, with the purpose of producing biogas from the laboratory. 2.- Develop a desktop application that streamlines and simplifies the methane gas calculation process that occurs when mixing some organic materials and their properties, and thus define whether the proposed mixture is productive or not.

The current energy base is a generator of CO2 emissions, the most abundant and main greenhouse gas responsible for global warming, as well as pollutants, sulfur oxides and nitrogen oxides. The environmental deterioration and the increase in fossil fuel prices make it necessary to investigate less aggressive energy sources with the environment at competitive costs in the market. Biofuels are an alternative for energy production due to their origin in the short carbon cycle, their emissions are considered almost zero, including biodiesel and bioethanol. The latter can be obtained from microalgae rich in carbohydrates and lipids, easy to grow in short periods of time. The objective of this research is to summarize the findings made about the existence of useful microalgae as raw material to produce biofuels in Mexican territory. An exhaustive review of the literature was carried out, which contributed to estimate the microalgal diversity in the country and its lipid contents as well as carbohydrates, with different species of the genera Chlamydomonas, Chlorella, Scenedesmus, Desmodesmus being found mainly.","PeriodicalId":329432,"journal":{"name":"Revista de Energías Renovables","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131867736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
