| Resumo: | Among the various environmental and social problems created by the capitalist production model, one of the largest is related to the production of organic waste, which, coupled with mismanagement, causes various problems for society, ample expenses, besides multiple damages to the environment. The increase in production involving livestock products has generated a high amount of solid and liquid waste (byproducts of farming activity). In this way, the balance between the production of animal excretions and environmental preservation must be sought by means of actions that allow adequate solutions for the treatment of these residues. In this context, the composting process appears as an alternative of better use of the organic residues and can be used as an effective tool in transforming this type of waste into a good quality fertilizer for plants. The present work aims to manage agropastoril organic solid waste by means of this technique. To support the construction, operation and maintenance process, a training was carried out with the cottar of the property in order to make him able to understand the composting process as a whole. The compound's montage was performed in piles, since such this configuration provides better conduction for the decomposition of the different types of materials, which were intercaled layered. The decomposition of the material was promoted from the design chosen for the pile, thus guaranteeing optimal conditions for the action of microorganisms. Two stacks were built, which were 3,0 meters long, 2,0 meters wide and 1,0 meters high. Important aspects such as temperature, humidity and days of compound turnover were carefully observed. At the end of the process, all material was sieved and 720kg of organic compound was produced. From the perspective of environmental engineering, the use of practices such as composting, using bovine manure, it is of utmost importance, because it guarantees an appropriate destination for this material, being therefore a good alternative to assist in improving the internal management of this type of waste in a farm and, with that, to promote environmental and economic improvements. |
