Project Statement

LCDVAL aims to illustrate the CRM value contented in LCDs via recovery techniques, therefore turning waste liquid crystal panel waste fractions into a resource for CRM.

Objectives and Targets

To unlock CRM content specifically indium from waste LCDs & increase the range and yields of this raw materials [measurement: achieve mg/kg glass (Metric) recovery of CRM; Indium tin oxide].

The research group previous ran a desk based study on “Indium recovery from LCDs” which is investigated the amount of indium present in different LCDs and reviewed the readily available techniques for indium recovery. LCDVAL will build on the knowledge based from desk based study and take the research a step future by conducting lab based recovery to optimise the indium recovery and other materials including rare earths as relevant.

To illustrate the automation potential of the hydrometallurgical process [measurement: process map and process animation]

To push Ireland to the forefront in the area of raw materials processing technologies [Measurement: 1 key note speech; publications]

To result in higher economic viability and investment security of processing operations [Measurement: Potential H2020 application]

The solution begins in work package 1 with the collation of the current research activities and desk based studies the research team at University of Limerick into a comprehensive literature review of CRM recovery techniques, database and surveys. This report will be distributed among the steering committee members and reviewed with key industry to guide on the selection of an optimised recovery methodology. The chosen hydrometallurgy based processes will then be trialled in work package 2 and understanding gained on how to optimise the process to maximise CRM recovery. The result of the trials will be reported and key influencing factors on the recovery rates and efficiencies will be specified. An evaluation of the process from an environmental perspective will also be undertaken. The potential to automate the process will be investigated in WP3 and process layout and model of the system developed as relevant to the findings. The commercialisation viability of the process will be investigated in work package 4 and exploration of European funding to take the technology to pilot stage.
