Biodigester Carseiros Production of biogas and Biofertilizer

The present work developed a prototype of biodigester in a conventional way. The construction of the prototype used materials that easily access the population, especially PVC materials and reusable scraps that can be found in any community. Furthermore, the prototype was created in order to facilitate the manipulation of this technology by the community in general. To obtain results, the pH parameters, and electrical conductivity (EC) of the organic matter introduced and the final by-product, the biofertilizer, being compared the results between them. The other survey to quantify biogas production was done using the Chen method (1983) perfected by Mito (2018), which resulted in the production of 0.215 m³CH4/ day, the experiment can be used daily as cooking gas, in addition to a second functionality, such as biofertilizer, such as fertilizer in plantations and nutritional control of the soil.
