Stage 4

In Romania, the annual generation of a large quatity of urban waste is one of the most serious environment protection problems, for which an unsafe and inadequate waste management may represent a potential environmental risk. The various waste management practices and methods imply the emission of pollutants in the environment, leading to numerous cases of soil and undergroud water contamination, implicitly causing health risks for the population. The present energy crisis and excessive environment pollution has led to paying greater attention to the sources of unconventional energy.

Correlated with the necessity to use various technologies in order to produce clean energy using regenerable energy sources, in this stage of the project we have made experimental determinations on pilot installations, one for biomass waste fluidized-bed roasting, and one for producing biogas from urban waste and using it in burning processes to check the existing possibilities of using it individually or in combination with fossil natural gas, as fuel. The figures show some of the experimental results obtained in the two pilot installations.



The objective of the project is the waste recovery by incineration and co-incineration respectively, as well as by obtaining biogas by means of anaerobic digestion. Table 3 presents the relative energy potential of biogas coming from various sources, in the process of obtaining biogas.

From the results obtained on the two pilot installations we can determine the necessity and possibilities arising from the use of the technologies presented in this stage in large-scale processes, at industrial level, for the improvement of the quality of life by reducing the level of pollution, and the improvement of the air quality respectively, with a direct impact on the population, as well as for obtaining a certain degree of energetic independence and autonomy, by using local / regional regenerable resources.
