Part of the book: The Future of Biorefineries

Abstract

The biorefinery concept emerged as an alternative to decrease the greenhouse gases emissions by the industrial section while producing bioenergy and value-added products. This chapter evaluated a critical analysis of the residues derived from eucalyptus harvest to support decision-making for a biorefinery implementation in the Administrative Region of Campinas (ARC), São Paulo State, Brazil. Brazilian official data for forestry extraction were collected for the eucalyptus production areas of the municipalities of ARC. RapidEye images were used to process, identify, and classify the areas occupied by eucalyptus and the chemical industries, aiming to compose a georeferenced database. Although most of the developments have been focused on processing technologies, it is critical to define the specific biobased products that should be produced considering market drivers such as demand, production flexibility, logistics, and supply chain configuration. The conversion of lignocellulosic materials present in forestry residues could produce several bio-based products after a pretreatment step. These products could replace fossil-based raw materials for the chemical industry, such as polyurethane, lignin, tannins, furfural, xylose, xylitol, polyphenols, and lubricants. It was possible to observe the existence of promising potential for the use of eucalyptus residues to produce a wide variety of chemicals. In the case of biofuels, the use of residual biomass is a primary factor for the transition to a viable and more renewable energy chain since eucalyptus residues are still little or not explored.

Keywords: biorefinery, eucalyptus residues, bioenergy, biofuels, bio-based products
