Resumo: | The uncontrolled generation of organic waste causes the decrease of the life of landfills. Alternative treatment processes such as anaerobic digestion of organic wastes may be a viable alternative to disposal of such organic waste, and the use of this technology can still generate gains using biofertilizer in agriculture. Thus, the present study aimed to evaluate the anaerobic digestion of Ceasa vegetables wastes from Cascavel-PR by adding swine manure doses (inoculum) in order to reduce the volume of waste going to landfills. Alternative 12 digesters were developed, and are added 29 liters of effluent (fruit and vegetable wastes) in each reactor, by adding inoculum 3 levels: 0, 1, 2, 3 liters (pig manure). During 50 days of digestion were analyzed the following physical and chemical parameters of the effluent: pH, temperature, turbidity, electrical conductivity, TS, VS, TOC and P concentrations. Satisfactory results were obtained in most of assessed parameters, TS reductions were observed in the levels of 60% in the treatment with 2 liters of inoculum. With respect to TOC was possible to obtain a reduction of 57%. With the obtained results it can be concluded that the manufactured biodigesters were effective in the digestion of Ceasa waste, however, the effluent can be used for biofertilization by pH correction, due to its acidity.
