Overview
The work approaches the study of some physical-mechanical and chemical properties of agricultural organic residuals which can be used in the biogas production in the plants in production in Cuba, using the co-fermentation of the same ones.
It has also been necessary to collect agricultural biomass, canteen waste, influent and effluents of a biogas plant ("Niña Bonita") next to Santa Clara's city, Cuba for their later analysis.
So much the samples of the biomasses investigated as (sorghum.49V-96, sorghum-132 R, sunflower JE-94, cassava, corn, sweet potato skin, bread, potatoes and peanut skin); of the influent and effluents of the investigated plant of biogas they were analysed in some laboratories belonging to the Central University of Las Villas. Other analyses were done in the biogas lab at Hohenheim University.
The maximum value of specifies methane yield achieved was with the sunflower JE-94 (0.393 m3/Kg VS), while the minimum value was reached with the peanut shell (0.095 m3/Kg VS).
The main objective of the work consists on determining some of the physical-mechanical and chemical properties like as carbon nitrogen ratio (C/N), specific methane production (m3/kg VS), total solid (TS), organic total solid (oTS), alkalinity (pH) and volatile solid (VS) in agricultural organic residuals and canteen waste, which can be used for the production of biogas under co-fermentation with animal manure under Cuban conditions. In order to do this we must development some experiment to syringes scale, to small scale and a real scale
