Fossil fuels (coal, natural gas and oil) are currently the main source of energy for
our society. The consumption of these for the generation of energy contributes
in a decisive way to global warming and to the climatic problems related to this
phenomenon. Biogas, obtained biomass, is an important source of clean energy
that can take solid, vegetable and vegetable liquids to obtain it, so the focus of
this study was the use of pineapple residues agroindustry. The methodology
consisted in three treatments, with three replications each by digestion and
anaerobic co-digestion, using as substrate pineapple husk (CP), residual water
sludge (LAR) and cows ruminal gastric content (CGRV). The largest biogas
generation theoretically calculated was the CP + CGRV treatment. For the biogas
yield, the LAR residue turned out to be the largest. Regarding the volume of CH4,
the best theoretical treatment CP + CGRV. During the monitoring of the
anaerobic digestion process (AD), the temperature remained within the
optimum range. In the nutrient contents of the biodigestate, the end of the
process of DA and Co-DA, the CP + LAR was higher in the nitrogen content, the
CP had the highest concentration of phosphorus and the three treatments
presented the same concentration of potassium. In terms of pH, the treatments
CP + CGRV and CP + LAR were maintained in the range of 6.5-7.5 towards the
methanogenic phase. However, it could be observed that the three treatments
generated biogas, but these results can be said that it is feasible to produce
biogas the agroindustrial waste obtained during the processing of the pineapple
(Ananas comosus L. Merril).
