Resumo

The aim of this work was to develop a detailed econometric analysis to compare a constructed wetland system - combined model, and a waste stabilization pond system - facultative pond, as a function of six different sizes of finishing pig farms and two waste management systems - wet and dry. The constructed wetland system using dried waste management showed the best economic results. This finding is due to the low-cost implementation a year both per animal and per kilogram of meat. This system also required the smallest area for waste treatment. The use of stabilization pond with wet waste management system showed a lower implementation cost a year per animal and per kilogram of meat, but it required large areas. The econometric analysis of both systems of wastewater treatment revealed an economy of scale.
