Conversion of organic waste through a biorefinery scheme into biofuels and value-added products: Overview and perspectives

Abstract

The amount of organic waste generated worldwide is increasing considerably every year, and not only does the disposal of this waste require economic resources, but also creates greenhouse gases that negatively impact the environment. An emerging technology that is aligned with the concept of circular economy and allows the revaluation of these organic wastes is
the biorefinery, from which biofuels and value-added products are obtained. Thus, in this work a review of the proposed biorefineries for the conversion
of organic waste is carried out, which highlights the feedstock used and the generated products, as well as conducting feasibility studies. It is concluded that more detailed studies are still required to evaluate the benefits of its application, and that the selection of conversion processes is important for the optimal obtaining of products.
