Thanks to a partnership between the INTA and the European Union, work is being done to develop an economically viable method that allows for the remediation of contaminated soils in La Planta, Caucete, using native plants to extract heavy metals from the ground.
Research and Results
Scientists from four nations are conducting this study in San Juan, the only location in Argentina participating in the project. Since the beginning of the research during the pandemic, significant progress has been made.
The plants used have proven to be capable of extracting toxins from the soil, which are then used to produce biofuels for ships and cars, as well as raw materials for the steel industry.
Remediation of Contaminated Soils
The process, known as phytoremediation, takes advantage of the plants’ ability to absorb contaminants, storing them in their leaves, stems, and fruits. In San Juan, in addition to the native plants, quinoa is being used due to its high pumping potential and rapid growth.
Circular Economy
Once dried, the plant residues are sent to Germany to produce biofuels and other useful products.
For example, zinc is reused in the steel industry to manufacture galvanized steel. This circular economy approach aims to confirm the economic viability of the process.
Future of the Project
The research is in its final phase, with the last definition expected for the next year. The results obtained so far are promising and could be crucial for the remediation of soils affected by mining liabilities.
The project has also opened the door to the participation of more local researchers and entrepreneurs through workshops and annual meetings.
