Auditoría del manejo de residuos oleosos en un grupo electrógeno de diésel

The generation of electricity has associated negative environmental impacts among which is the contamination by oily waste. The purpose was to audit the management of the oily residuals of a diesel generator and to propose corrective actions for the findings. The eight-step procedure was used in solving a problem. The audit criteria were established and, as evidences, the treatment organs were diagnosed, the receiving body and the oily water disposed were sampled. The concentration of hydrocarbons and fats exceeded the established limits. Hydrocarbon spills, increased system load and clogging were the main failure modes. A plan of 27 corrective actions was designed, which constituted conceptual ideas to improve environmental performance. The procedure can be generalized to other sets and thus contributes to sustainability in the distributed generation of electrical energy

Erosión hídrica del sector de playa del hotel Ancón, Sancti Spíritus, Cuba.

The purpose of this work was to assess the contribution of the storm drainage system of the Ancon hotel over the erosion of its beach sector and to propose a plan of corrective measures for their mitigation. A procedure based on the eight steps in the solution of a problem was designed, complemented with specific methodologies and tools. The water origin of the erosion was predominating, with manifestations of the gully erosion type. Rain erosive power, enhanced by technical and organizational deficiencies in the storm drainage system, as well as the influence of the erodibility of the land and constructed elements, increases flow and velocity rates. A corrective action plan to mitigate erosion based on hydraulic and coastal engineering solutions was designed
