Biogas
• Developing and evaluating the kinetics of anaerobic digestion in the
different biodigester models available.
• Supplying new biodigester models with biomass heating, stirring and
thermal insulation, for the purpose of increasing biogas production and
improving the efficiency of organic matter removal.
• Evaluating the use of biodigesters in the treatment of wastes from
swine and poultry production and consequent elimination of health risks.
• Developing and evaluating complementary systems for the final
treatment of liquid biodigester wastes.
• Evaluating the quantitative and qualitative characteristics of biogas as
a function of climatic seasonality and type of animal production system.
• Evaluating and developing mathematical models for estimating biogas
generation and evaluating the qualitative and quantitative characteristics
of biogas as a function of the effect of climatic seasonality.
• Evaluating the use of bio-fertilizers, such as organic manure, to replace
chemical fertilizers in grain and pasture planting systems.
• Evaluating the environmental the risks that the intensive use of organic
bio-fertilizers in grain and pasture planting systems would pose to
superficial and underground waters.
• Developing equipment for the use of biogas, instead of PLG and
firewood, as heat source in swine and poultry production facilities.
• Developing equipment for the use of biogas, instead of PLG and
firewood, as heat source in grain drying.
• Developing equipment to compress and transport biogas under low
pressure.
• Developing biogas-fueled machines and equipment for the
transportation and distribution of bio-fertilizers.
• Developing and adapting motors and generators fueled by biogas to
produce electric power in animal production systems.
• Developing ion exchange membrane, fuel cell, electric power
generators that use biogas.
• Developing low-pressure biogas storage systems for use in swine
and poultry production farms.
