ALR2000

The ALR2000 was the second series of development of the LCD recycling technologies under taken by Votechnik. The focus in this series was taking the machine from batch processing for individual LCD sizes to sequential processing for the different sizes. This series of developments also enclosed the entire machine with a built in carbon filtration system to capture any emission and ensure that machine was safe to be around.

The ALR2000 had a linear process flow where the LCDs were moved from one station to another for processing and removal of the CCFL tubes and liquid crystal panels. The machine used a mechanical conveying system to transfer the LCD through the process allowing more time saving and a higher processing rate.

ALR1000

A machine is born…

Under the leadership of Dr. Lisa O’Donoghue at the University of Limerick, a highly qualified team of postdoctoral researchers undertook the build of the first proof of concept machine the ALR1000 for LCD recycling. The research was commissioned and funded by the Environmental Protection Agency of Ireland, whose remit is to safe guard the Irish environment and implement the EU WEEE legislation at national level. The purpose of the machine was to depollute the LCDs of the CCFL tubes, which contain toxic mercury and the liquid crystal panel.

The team at the University of Limerick under took time motion studies of the disassembly of various flat panel displays and liquid crystal displays. They catalogued the variations in the different displays and looked for similarities of structure and configuration. Identifying this, they then developed a process to quickly access the components containing the toxic materials.

The process involved key incisions in the displays at critical points to release the components of interest.
The team then went to the laboratory where the first of its kind prototype was invented. The image inset shows the prototype as housed in the department of Design, Manufacturing and Technology at the University of Limerick in their automation laboratory.

The machine while rudimentary in design was ground breaking in that it validated the process – processing LCDs in batch mode set up for particular LCD sizes. The machine successfully proved that LCDs can be depolluted and recycled at high speed processing at a rate just over 1 LCD every minute and half.
Upon the success of this, the intellectual property was filed for international patent while the research team published key findings of the research studies in the Journal for Cleaner Production.
