LIXMIX - CIRCULAR ECONOMY APPLIED TO THE SUSTAINABLE RECOVERY OF ELECTRONIC WASTE.




DESCRIPTION

The increase in demand for electrical and electronic equipment (EEE) and the decrease in useful life generate a huge amount of waste electrical and electronic equipment (WEEE) from equipment such as mobile phones, television, computers, printers, modems, fax machines, photocopiers, LED/LCD Monitors, medical equipment etc.

This waste contains a variety of hazardous substances, which can cause environmental problems when not managed properly therefore recycling WEEE is of paramount importance to the environment. Furthermore, secondary metal resources such as WEEE contain base metals (Cu, Al, Zn, Ni…) and precious metals (Au, Ag, Pt…) comparable to the metal content in ores and concentrates. Printed electronic circuits in particular are a potential secondary source of materials, as well as a growing research topic known as urban mining. Likewise, metallized plastic waste represents a toxic waste whose management is complicated due to its composition (ABS plastic, Ni, Cu, Cr).

OBJECTIVES

The general objective of the project is based on the development of a methodology consisting of sequential leaching in two stages: bioleaching and electroleaching.
In the first, a leaching agent will be biologically generated from acid waste, extracting the base metals.
In electroleaching, an electro-Fenton process will also be used from waste, which will allow the extraction of valuable metals.
The general objective will be achieved from the following specific objectives:
- Define bioleaching methodology through the use of microorganisms as biological producers of leachants and adaptation to a sequential recovery process.
- Define an electroleaching methodology for the extraction of valuable metals through an electroFenton process
- Identification and selection of acid waste from our companies potentially usable both for the production of leachants in bioleaching and reagent for electro-leaching
- Design of a prototype for the recovery of metals based on the results obtained, taking into account the leaching yields as well as a future concentration and purification of the different metals contained in each stream.
- Analysis of the technical, environmental and economic feasibility of the proposed process in comparison with the processes currently applied.
- Analyze the legalization process of a waste (acid pickling) for its use as a by-product in order to minimize the current cost of waste storage and management.
- Transmit knowledge to our companies to promote their competitiveness based on the generation of new knowledge.
