Lignocellulosic waste as a second generation raw material in biorefining processes

Abstract:

There is global interest in replac-ing fossil fuels with renewable sources. The first generation of biorefineries relied on the utilization of food crops, spark-ing a debate on food versus fuel and questionable sustainability. To overcome this, the use of lignocellulosic raw materials was proposed, ranging from non-food crops to agro-forestry residues and waste. Based on this premise, a biblio-graphic review was carried out on the use of second-generation lignocellulosic waste for the production of bioproducts. It was investigated about the transformation processes used, the bioproducts obtained and the amount of waste of this type that are available in Latin America for use. The exploitation of this type of waste provides an opportunity for the development of the region by using low-cost raw materials to obtain products with added value.
