Management of Pig Wastes by Compost System

Abstract

The production chain of swine-breeding concentrates its production between a decrease in the number of active producers and the need to increase food production. A study case in loco brings to the fore the functioning of a compost system adopted by the Granja Barra Grande in Iporã do Oeste SC Brazil. Further, the paper investigates volume of waste produced monthly on the swine farm; describes the compost system on the farm; and produces a plan of activities based on 5W2H to provide the improvements that should be undertaken with a view to its growth, increase in wastes and their disposal. Theory relates the characteristics of the compost system and reduction of impact. The Granja Barra Grande had a monthly waste production reaching 728.12 m³, or rather, 24.27 m³ a day, of which 34.07% is employed in the compost system with an annual application of 2,976.82 m³. Since one cubic meter of compost concentrates 3,816.43 liters of wastes, the system under analysis produces a yearly 780 m³ of compost. Results show that, through compost processing, the farmer obtains assets, eliminates bad smell and permits an efficient fertilization of the soil. The compost process is an important stage to make viable intensive breeding swine breeding not only on the farm focused but in any producing region due to costs in the distribution of low-density wastes and to potential pollutant.
