Viabilidad económica de la utilización de biogás para la conversión en energía eléctrica

The economic viability of the electrical power generation using biogas from swine wastes, was determined. The analyzed biodigester is a continuous tubular model with brick concrete duct and plastic covering with a gasometer, in which the waste of 2.300 fattening pigs are deposited daily. The initial investment estimate for the installation was R$ 51.537, the system annual costs were R$ 5.700, for maintenance, R$ 4.400 for depreciation and R$ 1.370 for interests. It was found that an average consumption of 28 kW-hour-1 is the minimum that the system must reach to be economically feasible.

Coleta de informações para projeto de incinerador regional de resíduos sólidos urbanos (RSU)

The incineration of municipal solid waste has become a very interesting, in order that incineration reduces the amount of solid waste, which would be accumulated in dumps and / or landfill. Furthermore, it is possible to generate electrical energy by use of clean well known technology. To verify the feasibility of installing a plant for the incineration of solid waste with energy recovery, we must consider some basic requirements. For this reason, will be presented in this paper some factors that influence the project to install a plant of incineration with energy recovery.
