Análise estocástica da emissão de carbono do grapple skidder no arraste de feixes de árvores

During the entire production chain of planted Eucalyptus forests, wood harvesting is the activity responsible for the process that goes from cutting to processing the trees, which has the help of self-propelled machines that, during their activities, emit greenhouse gases, such as carbon. Therefore, the carbon emission was analyzed with historical data of fuel consumption of the grapple skidder in the skidding activity by means of the Monte Carlo method. The carbon emission in the activity of dragging the tree bundles, according to the stochastic analysis, presented a maximum value of 482,56 kg m³ and average 64,64 kg m³. During the hauling activity, the grapple skidder can emit more carbon when a greater number of maneuvers is performed, that is, greater engine rotation that causes a greater amount of fuel consumption, therefore, it emits more carbon into the atmosphere. With the stochastic analysis, the average carbon emission of the grapple skidder in the activity of dragging the tree bundles in the mechanized harvest of wood is 64,64 Kg m-3.
