Tittle:
Alternative Bioleaching process of metals from secondary resources (industrial wastes)
Summary:
A Belgian Research Centre developed (stage of development: technology validated in lab TRL 4) a microbial assisted leaching process designed for metal recovery from secondary resources. The technology is based on a new process integrating bacterial cell encapsulation for a higher resistance to dissolved organics and heavy metals. The research center looks for companies and universities for licensing patents, to develop European projects and further applications in other sectors (other residues)
Description:
A Belgian Centre for applied and basic research in microbiology (fundamental microbiology to bioprocesses development) has developed (stage of the development: TRL 4 - technology validated in lab) an emerging technology designed for metal recovery from secondary resources. Based on well-established know-how for copper-ores refinery and precious metal biomining, the microbial assisted leaching offers new opportunities for heavy and precious metals recovery from electronic wastes, end-of-life vehicles, spent catalysts and numerous industrial residues...

This technology offers :
- recovering opportunities for low metal-content residues which are not economically viable in conventional recycling technologies.
- Economical and environmental sustainable alternative to landfill of series of selected poly-metallic industrial wastes.
- Eco-friendly nature of biohydrometallurgy compared to chemical processes or pyrometallurgy, is supported by mild operating conditions (low-pressure and temperature, reduced chemical input).
- Cell encapsulation offers higher extraction rates by enhanced cell density, biomass protection against harsh medium conditions and facilitated continuous process.
- Good results with copper extraction e.g. from brake-pads manufacturing residues.
- Good performance/return compared to other bioleaching processes.
The process can be applied on polymetallic residues from several industrial activities: metallurgy (anode slags, dusts, speiss,...), catalyst industry, automotive industry,...

The Institution is seeking research collaboration, technical transfer, knowhow transfer...

Two types of partnerships are sought:
*on the industrial level:
-licencing patent rights regarding a new efficient bioleaching process
*on the research and development level:
- developing academic and / or industrial collaborations to explore applications in other application sectors;
- participate on an European project regarding circular economy
Advantages and Innovations:
- Economical and environmental sustainable alternative to landfill of series of selected poly-metallic industrial wastes.
- Eco-friendly nature of biohydrometallurgy compared to chemical processes or pyrometallurgy, is supported by mild operating conditions (low-pressure and temperature, reduced chemical input).
- Cell encapsulation offers higher extraction rates by enhanced cell density, biomass protection against harsh medium conditions and facilitated continuous process.
- Good results with copper extraction e.g. from brake-pads dust : 15% copper extraction in 48-72h
- Good performance/return compared to other bioleaching processes : pulp densities up to 20%
Stage of Development:
Under development/lab tested
IPs:
Patent(s) applied for but not yet granted
CommeR Statunts Regarding IPR Status:
Patent application in last stages
