The oil palm industry is one of the largest producers of residual biomass, leading to environmental and economic concerns. For this reason, the concept of biorefinery is emerging as a means to create new ways of converting biomass into new types of renewable products bioenergetics that can contribute to the reduction of greenhouse gases. In this context, this document presents a study that consisting of a biorefinery configuration in a Palm Oil Mill (POM), considering the fast pyrolysis process to produce bio-oil and biochar, and an extraction / trans-esterification stage to produce biodiesel and glycerin in the POM. The environmental impacts associated with a production process of a biorefinery system were calculated using the life cycle assessment methodology through the IMPACT 2002+ method, which analyzes the environmental impacts in four categories of damage (human health, ecosystem quality, climate change and resources). Therefore, to produce bio-oil, biodiesel and electricity were obtained 52 mPt, 120 mPt and 127 mPt of total impacts, respectively, demonstrating that the fast pyrolysis process to obtain bio-oil it does not generate considerably high environmental impacts compared with the other products obtained in the biorefinery in any of the categories of damage assessed.
