Management for the production of 2G biofuels: Review of the technological and economic scenario

Abstract:

There is currently world growth in energy consumption, and biofuels are the viable alternative to reduce dependence on fossil fuels, minimize negative environmental impact, and increase the use of alternative energy sources. Ethanol has been part of this solution, and its industrial production evolves according to the treatment applied to the raw material. Second-generation (2G) production from lignocellulosic material is an alternative that promises great opportunities and performance from biofuel. However, biomass treatment is costly when compared to first-generation (1G) production methods. The objective was focused on describing the technological advances and the economic scenario that defines the business management enabled to produce 2G biofuel. The methodology was based on a systematic review of the literature, with a descriptive level. The results emphasized that agro-industrial management aimed at ethanol production will depend on considerations related to the availability of economic, technological, and innovation resources and its relationship with stakeholders. It is concluded that greater technological development will be achieved in the coming decades at a low cost. For now, the efficiency in 2G ethanol production and the combinations of 1G-2G ethanol production methods could mean a key element to complement the energy demand of the countries that require it.
