Evaluation of the potential of biogas generation, of different organic waste, generated in Tabasco

Abstract

The use of organic waste, as a basis for obtaining renewable energies, is a booming activity in developed areas of the European Union, and Mexico, in specific, the southeast area where Tabasco belongs, is the source of various substrates that can be exploited. The present objective is to determine the analytical characteristics of different substrates generated in the State of Tabasco, and to determine theoretically its potential in obtaining biogas, thermal and electrical energy. The analytical results, indicate that pork and cow excreta, and the water lily, have the highest SVT content, with 82.82 ± 1.33%, 81.41 ± 1.43% and 81.19 ± 2.52% respectively. The theoretical biogas production was higher in pig substrates (20.21 m3 d-1), chicken (15.73 m3 d-1), dog (11.57 m3 d-1) and lamb (9.25 m3 d-1). In heat capacity, the chicken and pork substrates, present the highest theoretical capacity in substitution of LP gas with 5.02 and 6.45 kg d-1, respectively. Finally, the theoretical values of electricity generation were presented in the substrate chicken, pork and lamb, with 2,156.71, 2,404.37 and 2,475.91 kW year-1, respectively. With the present work, demonstrates the potential of various substrates in energy production, both heat, as electric.
