Razões pela não utilização de biodigestores em granjas suinícolas em Marechal Cândido Rondon PR

Abstract

The actual economic model takes the society to exploit the natural resources in an inadequate way, besides generating anthrop systems which are not always in concordance with nature. The swine culture is one of these systems, which needs some policies and actions in order to give the activity some sustainability. This research aimed at identifying the reasons why bio-digestion technology is not used by a group of producers in Marechal Candido Rondon, Parana state, Brazil. With this goal, it is demonstrated which procedures of bio-digestion there are in the city, and which bio-digesters are the most popular there. In addition, it is showed the conceptions of environmental management, development, and economic growth, by integrating the idea of sustainability. Some research, made in 2003, related to the use of bio-digesters in the end of the last century, by some Embrapa swine and poultry technicians, and also some similar research in Toledo, Parana state, Brazil, helped the data analysis, comparing the facts of that time with the actual differences. It was identified that producers poor education, lack of knowledge about bio-digestion technology, and the non-use of the biogas from the anaerobic digestion, took them to a lack of credibility of the process, which at the current moment is not a different reality. The support offered that time was not sufficient, as well as the incredibility of the technicians dispended with the producers, made the latter use the bio-digester as a waste facility. Nowadays, that same incredibility may occur if there is not any commitment of the competent sectors and associations, in order to develop effective actions to inform and encourage the producers for using the adequate resources in the swine culture. In this case, the consequences for the environment may be disastrous.
