TL;DR

Agro‑industrial residues, especially in Colombia where ~71 billion tonnes are produced annually, are largely discarded in rivers and fields, yet represent a valuable resource. The review aims to explore how integrating agro‑industrial residues can sustainably boost bioproduct production in Colombia’s agricultural and livestock sector. It proposes a framework that examines each bioprocess stage for integrating residues to produce microbial biomass, metabolites, or enzymes. The authors conclude that utilizing these residues can drive bioeconomic policies and foster a circular bioeconomy centered on a modest biotechnology industry.

Abstract

Agro-industrial residues are an important source of useful compounds. Colombia produces about 71 billion tonnes of agro-industrial residues per year as a result of the presence of different ecological niches that allow the cultivation of around 200 crops throughout the year. These residues are disposed of mainly in rivers and open fields. This review presents opportunities for a sustainable transformation of the Colombian agricultural and livestock sector by increasing the production of bioproducts with the integration of agro-industrial residues, and the co-production of microbial biomass and metabolites or enzymes in such bioprocesses. Likewise, a framework for the development of bioproduct processes is presented, each stage of which will be studied from a perspective of integration of agro-industrial residues. The use of these underutilized resources has the potential to drive bioeconomic policies and support a circular bioeconomy with a small biotechnology industry in focus.
