Resumo:
The deforestation, mainly verified in the Amazon region, has declined, but deforested areas, due to anthropic actions such as agriculture, or pastures opening, are still a hindrance, since the resilience process requires time to act. In this bias, the Agroecological Zoning, Production and Management of Oil Palm Culture in Amazon (ZAE-Dendê), evaluated the degraded areas in the Legal Amazon, aiming the palm plantation to recover them, based on the best practices. The present work goes beyond, evaluating the implantation of palm oil as a way of recovering degraded areas in Pará; the power generation from palm oil processing residues; as well as analyzing carbon dioxide reducing potential. The methodology used, covered the selection of degraded areas in Pará as the study area. Based on theoretical references some data were consolidate: the production of fresh fruits bunches (FFB) per hectare, the amount of waste per tonne of FFB, power generated from the residues and CO2 value fixation and emission. The results related to the CO2 emissions and fixation showed that the palm oil culture has the potential to reduce a range from 180 to 500 million tons of CO2eq., in addition to avoiding emission of 550 to 2,204 million tons of CO2eq., in a production cycle (25 years). The power generation potential verified from the anaerobic digestion of the liquid effluent range from 212 to 531 TWh during a palm oil production cycle. These data attests palm oil residues to become an alternative energy resource, as well as an alternative to degraded areas recovery. Therefore, this work is a subsidy for an Integrated Resource Planning elaboration.
