How agro-industrial wastes abundant, low-cost, and nutrient-rich can be repurposed as co-substrates in biostimulation and bioaugmentation strategies to enhance hydrocarbon biodegradation. By utilizing these wastes for the production of biosurfactants and enzymes, the study offers a sustainable alternative to conventional microbiological media, addressing two critical environmental challenges:
The study contributes to the field by:
- Proposing a circular economy approach: converting waste into a bioremediation solution.
- Tackling key technical barriers, such as low hydrocarbon bioavailability and high costs of remediation, through biosurfactant-mediated enhancement.
- Providing a foundation for large-scale, eco-friendly applications in oil-contaminated environments, particularly in developing regions.
Why Is This Important?
With growing global concern over oil pollution and hazardous waste, there is an urgent need for low-cost, scalable, and sustainable remediation solutions. This research addresses that need by combining green biotechnology with waste management innovation, showing a promising path forward for both environmental protection and resource efficiency.

Local agro-industrial and organic waste can be effectively transformed into valuable tools for environmental remediation through the application of technologies such as pyrolysis, composting, anaerobic digestion, and biosorption. For example, plant residues, husks, manure, and food waste can be processed into biochar, compost, or biosorbents that have the capacity to bind heavy metals, neutralize pollutants, and regenerate degraded soils. These materials can be used for soil and water decontamination, air quality improvement, or biogas production as a renewable energy source. In local communities, especially those with a strong agricultural sector, this presents a significant opportunity to address environmental issues while economically utilizing waste. My position is that such waste should no longer be seen as a burden, but as a resource that—with minimal investment and proper organization—can play a key role in enhancing sustainability and environmental protection at the local level.
Agro-industrial wastes can be repurposed as low-cost, nutrient-rich co-substrates to produce biosurfactants and enzymes that boost hydrocarbon biodegradation. This sustainable approach simultaneously enhances oil pollution cleanup and reduces waste, supporting a circular economy.
En bioensayos desarrollados en ECOPETROL Cartagena Colombia, es muy seguro y efectivo@ el trabajo con bacterias nativa de la zona contaminada con hidrocarburos polinuclares y con metales pesados como vanadio y sirconio. Como resultado de los bioensayos, se desarrollo un sistema de tratamiento a escala industrial para estos efluentes cargados con hidrocarburos con resultados altamente eficientes y demostrando que este sistema si cumple con los objetivos de depuración planteados a gran escala.
