Redução de emissões de CO2 pela produção de biocombustíveis a partir de óleo de dendê na Amazônia Brasileira

Abstract

The study aims to estimate the reduction of CO2 provided by the production of biofuels from palm oil in suitable areas, according to the "land use plan-Palm Oil" of the Brazilian Amazon. These estimates, still lacking in the literature, are part of the government guidelines to climate change. Such guidelines involve the measurement of two potential carbon pools: i) the fixation of atmospheric CO2 from the accumulation of biomass through croplands and ii) the reduction of CO2 emissions arising from the replacement of fossil fuels by biofuels (less polluting), generated from palm oil. The results show that over the cultivation period, 151.85 Mg.CO2eq.ha-1 can be stocked in above-ground biomass. In 35 million hectares scenario of potential use for the production of palm oil in deforested areas of Brazilian Amazon 5.3 billion Mg.CO2eq could be absorbed with the plantation. However, approximately 90% of the CO2 absorbed returns to the atmosphere during the production process due to low technology applied, making essential the reuse of waste production to increase the efficiency of CO2 reduction.
