lcd panel recycling factory

Liquid Crystal Displays (LCDs) have replaced Cathode Ray Tubes (CRTs) as the main display devices in recent years. To satisfy the increasing demands, billions of LCDs are manufactured annually. As more LCDs are produced and used, the amount of LCD waste is increasing at an alarming rate. Current treatment technologies can disassemble LCD into multiple components and recycle them according to their materials. However, there is no suitable model for treating LCD panels. Research has repeatedly shown the harmfulness of liquid crystal, indium and other heavy metals which LCD panels contain. As a result an increasing number of countries have classified LCD panels as hazardous waste. Because of this, future processing of LCD panel waste will require on-site burial, burning, or physical disposal, not only increasing processing costs, but also causing environmental damage. This is a huge problem. That is why this recycling technology for waste LCD panels is a kind of revolutionary breakthrough.

The pilot plant handles 3T of waste LCD panels daily, with a liquid crystal recycling rate of 100%, indium recovery rate of more than90% and glass recycling rate of 100%

Liquid crystal is the main component of LCD. It is a chemical with a high unit cost, high stability and low biodegradability. While the harmfulness of liquid crystal is uncertain, its structure contains a large volume of benzene rings, fluorine, chlorine, and bromine, which, if buried, may seep into subterranean water systems and impact ecosystems. Physical processing entails breaking down LCD panels and adding them to cement or concrete, which does not remove liquid crystals and heavy metals from the panels, so they may still enter and harm the environment following rain or washing. Based on environmental and economic considerations, the liquid crystal in the LCD panel should be reused.

To prevent the pollution caused by waste LCD panel disposal, and to control processing costs, ITRI thoroughly analysed the characteristics and reusability of each material contained in LCD panels, and designed a logical separation procedure according to the associations between each material, first separating liquid crystal, indium, and glass, and then developing purification technology for each material which enables the reuse of these materials. Liquid crystal can be reused in new LCDs or liquid crystal smart windows. Indium can be refined as the raw material of sputtering targets. Glass can become a humidity-controlling green building material or heavy-metal adsorption material.

ITRI’s pilot plant can treat 3 tons of waste LCD panel per day of operation, producing 3 kilograms of liquid crystal, 750 grams of indium, and about 2,550 kilograms of glass, which can be reused as humidity-controlling green building material or heavy-metal adsorption material. ITRI’s team uses the pilot plant for technical verification of on-line scrap LCD panels and end-of-life LCD panels. ITRI can build the LCD panel processing center for LCD manufacturers and e-waste recycling companies.

LCD displays that contain mercury pose a significant threat to the environment, as well as the companies disposing of them, historically public opinion hasn’t been very kind to companies who discard waste stream management and irresponsibly dispose of their waste. Sadly, the threats associated with LCDs don’t end with the environment, those handling old, cracked or damaged LCD displays must be properly trained and protected by safety equipment or risk serious serious bodily harm. This is why it’s important to leave recycling LCD displays to capable and responsible recyclers like Cleanlites.

Looking at several factors, LCD-S RECYCLING has been designed in order to meet LCD and LED technology based monitors recycling requirements. We placed operators’ health first. The entire system has been studied not to endanger them while removing backlighting neon tubes. After carefully assessed the product and its derivatives, we opted for a manual disassembly line in order to be able to recover all the circuit boards, separate plastic and metal during the disassembly. Considering the risk of neon tubes breakup during handling, a manual procedure can avoid dangerous mercuric oxide leakages.

Basic line includes six pneumatic and various tool equipped disassembly workstations, one-neon-tube extraction machine and one flat processing machine, which allows the following indium recovery. To ensure operators and working environment’s safety, an extraction system with HEPA filter (insideextraction cabin of neon tubes) and an extraction sleeves system (in the flat treatment zone) are provided along with the line. Thanks to this system, more than 90% of television or LCD/LED monitor can be recycled and the separated products can be soldwithout further manufacturing operations. Disassembly line plays an important role in determining hourly production capacity, while machines can reach more than 60 pieces per hour. Measures vary according to client customization preferences. Installed power (including extraction systems) is 22 kW.

The patent covers all the LCD panel treatment steps, starting from the initial shredding to the final recycling step of glass and indium, applying a “zero waste” approach, where all the materials of the original LCD panel are recovered.

Current techniques for recovering devices that use LCD panels require the disposal of the screen as non-hazardous waste. However, the content of potentially recoverable material, such as glass, the main component of the panel, and ITO, a film composed of indium oxide (90%) and tin oxide (10%), has pushed research towards the development of new recovery processes. The patented process allows a zero-waste treatment to be carried out, optimizing the steps for the extraction of indium with a new pre-treatment and a new valorization of a fraction previously considered as waste. This process has also numerous advantages compared to the known systems for treating LCD screens at the end of their life and can be used in any recycling facility used for treating special waste.

They were presented both awards at The R&D 100 Awards Gala held in Orlando, Florida on Nov. 17, 2017. See the full list of 2017 R&D 100 Award Winners here.

With more and more electronics in the home and the car featuring liquid-crystal display (LCD) screens, reducing the environmental impact once the devices are no longer used is crucial moving forward.

Research has repeatedly shown the harmfulness of the liquid crystal, indium and other heavy metals which LCD panels contain, but currently there is no suitable model for recycling these panels

Researchers from the Industrial Technology Research Institute (ITRI) are working to change that, developing a new LCD Waste Recycling System that is cost-effective, does not produce any waste and will allow manufacturers to save and reuse some of the valuable heavy metals used to create LCD panels. ITRI received a 2017 R&D 100 Award for the technology at the R&D 100 Awards Gala held in Orlando, Florida on Nov. 17, 2017. At the same event, ITRI also received a Merit in the Special Recognition: Green Tech category for its LCD Waste Recycling System.

“LCD panels, which are only a few millimeters thick, contain over ten kinds of materials, making their disposal and recycling especially difficult,” Chien-Wei said. “We thoroughly analyzed the characteristics and reusability of each material contained in LCD panels, and designed a logical separation procedure according to the associations between each material, first separating liquid crystal, indium, and glass, and then developing purification technology for each material which enables the reuse of these materials.”

The method begins with a panel-smashing system that shatters the LCD panel, exposing the liquid crystal. The separated LCD panel then enters the continuous liquid crystal extraction system and an agent that can be used on multiple cycles extracts the liquid crystal. The liquid crystal is exposed on the surface of the glass substrate, enabling the system to shorten the processing time by integrating the extraction and purification functions.

The impurity is removed by a salt adsorption method. After the liquid crystal has been removed, the panel fragments enter the indium extraction system and an agent is used repeatedly as a scrub to enable the removal of the indium from the panel fragment.

Extracting liquid crystal from waste LCD panel achieves a nearly 100 percent liquid crystal recovery rate and a 90 percent recovery rate of indium. The process could reduce the production of new liquid crystal, lessening the environmental impact.

“Treating waste LCD panels with this system can transform the panels’ material [liquid crystals, indium, and glass] into valuable, reusable products, not only increasing profits but effectively reducing the production of waste material,” Chien-Wei said.

“The liquid crystals with halogen-substituted aromatics are designed and synthesized for LCD,” Chein-Wei said. “Their production process and their final disposal both cause severe health and environmental impacts. However, people cannot get this information.

“Waste LCD panels are generally disposed of in landfills or by incineration in most countries, due to lack of proper environmental regulation. Without strict environmental regulation, it is difficult to promote new disposal method.”

Current treatment technologies disassemble LCD devices into multiple components and recycle them according to their materials. However, there is no model for treating LCD panels.

To physically process the panels, the panels must be broken down and then added to cement or concrete, which does not remove liquid crystals, indium, tin and molybdenum from the panels. Therefore, the liquid crystals and heavy metals could still enter the environment following rain or washing.

This has led to an increasing number of countries, including Hong Kong and China, to label LCD panels as hazardous waste. This requires future processing of LCD panel waste to be buried on-site, burnt or physically disposed, which increases both the processing costs and the environmental damage.

To test the new technology, ITRI has built a pilot plant that can treat three tons of LCD panel waste per day, producing three kilograms of liquid crystal, 750 grams of indium, and about 2550 kilograms of glass, which can be reused as green construction material or heavy-metal adsorption material.

While analyzing the strength properties, slightly smaller values were observed for the concretes with LCD admixture, in relation to the reference concretes CI.0 and CII.0. The differences in the obtained values are differentiated, exhibiting no clear tendency. They are most pronounced in the tensile strength test; however, due to the high coefficient of variation (over 10%), they cannot be subjected to a comparative analysis. Generally, it can be stated that lower values were usually found in the concretes with LCD addition. Such observation can be explained both by a higher air content in the concrete mixtures with LCD admixture (the considered concretes exhibited diversified consistency with low degree of liquidity within two classes), as well as the conchoidal fracture of LCD grains. The conchoidal fracture, due to its glassy and smooth texture, deteriorates the mechanical adhesiveness of cement paste to aggregate granules, despite its low porosity found while examining the interfacial transition zone (ITZ). Nevertheless, the low share of the admixture should reduce its significance. It should also be emphasized that extending the maturation time substantially mitigates the differences in compressive strength values. Following 90 days of maturation, all concretes reached the same class. which is especially prominent while applying the CEM II/B-S 42.5 N cement that is characterized by a slower improvement of the strength parameters in relation to CEM I 42.5 R.

The obtained correlations can be described by the equation y=0.39x2−0.02x−2.23, which is characterized by a coefficient of determination R2 = 0.83 and relatively low errors in the intercept (respectively 28%, 25%, 28%). The higher the water-tightness, the higher the frost resistance and the lower the mass loss. The reference concrete CI.0 is characterized by the lowest water-tightness (deepest water penetration), which corresponds to the highest mass loss during the water tightness test. An increase in LCD admixture to 2% resulted in 3-fold decrease in the mass loss of the samples.

Based on the research of Batayneh et al. [64] concerning the impact of various waste materials on the properties of concretes and hardened concrete, it was found that the use of aggregate made of recycled concrete, due to the shape and texture of the grain surface, significantly reduces the workability of the concretes. Similar observations were made when using crushed plastics. In our own research, the impact of LCD additive with significantly smaller amounts and completely different mineralogical and chemical characteristics did not significantly affect the consistency of the mixtures.

The use of 20% recycled plastics or concrete aggregate according to Batayneh et al. [64] reduces the compressive strength compared to reference concrete with natural aggregate. Despite the small amounts of LCD addition used in our studies, similar relationships in compressive strength values were observed in the early maturing periods (see Figure 5). However, after a longer maturing period (90 days), the same compressive strength classes of the tested concretes were obtained.

As a result of research of Mahesh and co-workers [65] regarding the impact of waste from polyethylene plastics, it was found that despite the reduction of early compressive strength of tested concretes (5–10% of the used waste), their compressive strengths after 28 days were comparable to the reference concrete [65]. Similar correlations were observed in own research after the use of LCD as an additive (Table 10).

If you have an outdated computer or two in your basement or old cell phones packed away in a box, you"re not alone. While most electronics from residences can legally be discarded with household trash, the department recommends reusing, donating or recycling it.

All businesses, charities, non-profits, schools, churches and public and governmental agencies in Missouri cannot legally discard certain electronics in Missouri landfills. They are required by federal and state law to properly manage certain unwanted electronics. Electronics classified as a hazardous waste must be regulated as a hazardous waste under the Missouri Revised Statutes, sections 260.350 to 260.430, RSMo, also known as the "Missouri Hazardous Waste Management Law." Reusing or recycling through a legitimate electronics recycler will help ensure that your facility complies with the law. For additional information on the legal requirements, contact the department"s Waste Management Program.
