BIOPROCESSING

Bioprocessing involves the use of biological systems, such as bacteria, fungi, or enzymes, to carry out chemical transformations, particularly in the extraction, recovery, or removal of metals from various types of waste. It represents a cleaner and sustainable alternative, offering high selectivity, reduced energy consumption, and lower environmental impact. 

Among the most studied bioprocesses are bioleaching, where microorganisms solubilize metals from solid materials, and biosorption, in which microbial biomass binds and concentrates metal ions from liquid residues. These techniques are particularly valuable for recovering critical metals from low-grade ores, mining tailings, industrial effluents, and end-of-life products.

At LAREX, bioprocessing is a strategic research front, aimed at developing innovative and environmentally responsible technologies for metal recovery. The laboratory focuses on identifying efficient microbial strains and optimizing conditions for metal solubilization and adsorption. Key research lines include the bioleaching of metals such as copper, cobalt, and rare earth elements from solid industrial residues, and the use of fungal and bacterial biomass in biosorption processes for the treatment of contaminated effluents. By advancing these biotechnological routes, LAREX contributes to the circular economy and the sustainable management of strategic raw materials, aligning scientific research with industrial and environmental needs.
