-“These chemicals are semi-liquid and can get into the environment at any time during manufacturing and recycling, and they are vaporized during burning,” said University of Saskatchewan environmental toxicologist and lead author John Giesy in a press release. “Now we also know that these chemicals are being released by products just by using them.”

-The researchers found the specific monomers isolated from the smartphones were potentially hazardous to animals and the environment. In lab testing, the chemicals were found to have properties known to inhibit animals’ ability to digest nutrients and to disrupt the proper functioning of the gallbladder and thyroid–similar to dioxins and flame retardants which are known to cause toxic effects in humans and wildlife.

-To be clear, the researchers didn’t observe any adverse health effects from the accumulation of liquid crystals in the human body; they only found that these crystals do in fact leak from devices, and that they have the potential to be toxic. “We don’t know yet whether this a problem, but we do know that people are being exposed, and these chemicals have the potential to cause adverse effects,” said Giesy.

-If you crack LCD screens and find the liquid crystal leakage, don’t panic. Just remember that the liquid crystal materials might not be more toxic than your detergents for stove or washroom. Just wash your hands with soup throughout. Never try to play with it or even worse to taste it. The liquid of the cracked computer screen will not evaporate, no emissions worries.

-Any electronics has environment impact and can’t be used landfills. If you want to get rid of old LCD monitors or LCD TVs, give them to electronic collection stations. Let’s the professionals to handle them. They will extract some precious metals/parts and make them into something useful or at least not hazard. FYI, liquid crystal materials are retrievable.

Scientists have discovered that LCD screens leak chemicals into just about every environment where they are found, according to a new study, and these particles have the potential to be toxic over time.As described in a study published last week in Proceedings of the National Academy of Sciences, researchers collected dust samples from seven buildings in China: a cafeteria, student dorm, classroom, hotel, home, lab, and an electronics repair shop. Nearly half of the 53 samples tested positive for liquid crystal particles—which are supposed to stay sealed in the screen after manufacturing—even in places where there were no LCD devices at the time of collection.AdvertisementThe international research team analyzed 362 chemicals used in LCD screens and found that nearly 100 have the potential to be toxic. These particles don’t break down quickly and have "high mobility" in the environment. When inhaled or ingested, according to the study, these particles can build up in the body over time with toxic effects, potentially causing digestive problems and other health issues.“These chemicals are semi-liquid and can get into the environment at any time during manufacturing and recycling, and they are vaporized during burning,” said University of Saskatchewan environmental toxicologist and lead author John Giesy in a press release. “Now we also know that these chemicals are being released by products just by using them.”According to the study, these chemicals are "simply filled" into the space between polarizers (light filters) during manufacturing and are not chemically bonded to any base material. This means that "they can be released during production; through wastewater; or during active use, disposal, or recycling."To be clear, the researchers didn"t observe any adverse health effects from the accumulation of liquid crystals in the human body; they only found that these crystals do in fact leak from devices, and that they have the potential to be toxic.

“We don’t know yet whether this a problem, but we do know that people are being exposed, and these chemicals have the potential to cause adverse effects,” said Giesy.AdvertisementLab testing showed that the hazardous substances found in phones were similar to flame retardants, which have proven to be toxic to living creatures, creating problems with animals’ digestive systems and hindering their ability to absorb nutrients. They also disrupted their gallbladders and thyroids.The team says the next step is to understand the effect of these chemicals on humans, animals, and the environment. “Since there are more and more of these devices being made, there’s a higher chance of them getting into the environment,” said Giesy.Right now, there are no standards for measuring them and no regulations limiting exposure to them. “We are at ground zero,” he said.Giesy’s previous work was the first to shed a spotlight on toxic perfluorinated and polyfluorinated chemicals (PFCs). PFCs used to be in all kinds of oil and water-resistant products such as raincoats and non-stick pans. His findings led to a global ban of PFCs.

Despite the magical appearance of modern screens, these marvels use very real resources. Monitors have long been the most resource-heavy parts of a modern computer, due in no small part to their size. Because of their size, a monitor manufacturers’ usage of certain compounds creates greater environmental concerns than the computer to which the monitor is attached.

Cathode Ray Tube Basics The first monitors were built off of much of the same technology as televisions. Known as Cathode Ray Tube, or CRT, monitors, these behemoths use a single, large vacuum tube with an electron gun at one end which fires light through a mask. The mask is charged in such a way to block certain wavelengths at specified locations, creating images. These monitors have been largely replaced by Liquid Crystal Displays, or LCDs.

Liquid Crystal Displays Liquid crystal displays are significantly thinner, lighter and higher image quality than CRT monitors. LCDs use a layer of specially made crystals mounted to an electrical grid. Small charges at different coordinates of the grid can change the color of each reactive crystal. A small fluorescent or LED bulb is then mounted along the long edge of the monitor to light it up.

Chemicals of CRT The biggest chemical concern in a CRT comes from the tube itself. The glass vacuum tube is lined with a significant amount of lead – as much as 4 pounds by some estimates. Cadmium is another highly toxic mineral found in CRT monitors which threatens workers who dispose of these electronics. To a lesser degree, CRTs also contain arsenic.

Chemicals of an LCD LCDs made great strides towards eliminating the chemicals used by its predecessor, the CRT. However, LCDs still contains small amounts of lead as well as mercury in fluorescently-lit models. In addition to the chemicals actually contained within the LCD, the manufacturing process of the liquid crystals uses nitrogen trifluoride, a chemical known to have an impact 17,000 times greater than carbon dioxide on global warming.

The components in computers and monitors contain many different toxic materials. This may not affect the average user working on one PC, but it does cause problems when equipment is recycled or discarded in bulk. If you are considering upgrading your office computers, you may not give much thought to how you"ll dispose of your old equipment, but when the time comes, you should know what is in the box and behind the screen.

Toxic Components in Computers The central processing unit in a computer contains toxic substances, and lead is found in circuit boards. Metal plates and housings may contain chromium, which is used to harden and protect metal plates from corrosion. Motherboards and connectors often contain beryllium. Cadmium is commonly found in chip resistors, semi-conductors, infrared detectors, stabilizers, cables and wires. Circuit boards, switches and relays contain mercury as well chromium. Brominated flame retardants are used in many components, including circuit boards and plastic casings.

Toxic Components in Monitors Older cathode-ray tube monitors may contain up to eight pounds of lead. Newer LCD and flat-panel monitors typically don"t have this much lead, but they do contain some and copper, too. The lamp used to illuminate the screen is likely to contain mercury, and the coating inside the screen may be made from cadmium. Brominated flame retardants are commonly found in many monitor components.

E-Waste According to the Electronics TakeBack Coalition (ETBC), the U.S. disposed of 423,000 computers and 595,000 monitors in 2010. Just 40 percent of computers and 33 percent of monitors were recycled; the rest were trashed. E-Waste is a serious environmental concern. Toxic materials in computer components can harm the environment and, if they enter food chains, they can harm humans too.

Recycling Businesses don"t typically buy new computers or systems because current hardware isn"t suitable for a purpose. Instead, they upgrade to improve performance, and old equipment may still have some value. These computers can be refurbished or sent for recycling -- even a broken PC contains components that are valuable and can be reused. Most major manufacturers offer businesses some form of recycling service. Some also offer trade-in discounts or cash for old equipment that could help cover some costs of a new system.

Technology is constantly evolving, bringing us new and better devices that leave us questioning what we ever thought was so great about those old ones in the first place. Last year’s mobile phones, TVs, and computers that use LCD screens are now dated by ever-improving models and a better grade of LCD – so replacing and upgrading the technology is important.

So, what should we do with these old devices and LCD hardware with a lifespan of 10-20 years that we now have lying sad and forgotten in the corner, in the attic, or out on the curb? Recycle them, of course! LCDs have their own regulations for recycling, so here are some tips on how to recycle your old LCD screens and devices.

LCDs that were manufactured before 2009 use cold cathode fluorescent lamps (CCFLs) to backlight the display. These CCFL displays contain mercury, which makes them hazardous to dispose of or incinerate. Other electronic products can contain hazardous chemicals, such as heavy metals and brominated flame retardants. These materials can leak out of landfills and into groundwater, streams, etc., or can be transformed into “super toxicants” while being incinerated. Throwing away these types of devices can clearly be harmful, even today. There are still some harmful chemicals and materials inside electronic devices that will damage the environment if they aren’t disposed of properly—and many times, they aren’t.

Another big problem is that because of the turn-over rate of these electronic devices, LCD screens are just left sitting in landfills. Since they need to be disposed of in certain ways, they’re left to sit and waste away, taking up space in the landfills. Many states have laws prohibiting the disposal of electronic waste in landfills. Because of that, LCDs are likely to sit and rot, or be incinerated in large quantities. They also could be shipped off to other countries that don’t have these prohibiting laws, which is definitely not the best solution to the problem.

Many times, we get new and better gadgets before the current one even needs replacing. That old TV still works, still shows the picture clearly and there’s not a scratch on it. But this new one…well, it’s bigger. It has the Internet capabilities built right in and it can do backflips! Okay, not really, but the point is that we tend to get something new while we still have a perfectly functioning, but slightly older, model. Instead of keeping it in the attic, you can donate it or recycle it to companies and stores in your area that will take it. These places can resell it to people who don’t have the latest backflipping TV, mobile phone or tablet.

Since the issue was raised, there has been much research performed on the best method for recycling LCD screens. Different facilities have different ideas, practices and processes. Some of these processes include removing the hazardous waste materials from the screens/monitors; others believe in completely taking apart the device/screen piece by piece and seeing what can be resold or refurbished, then disposing of the rest in environmentally friendly ways.

Almost 98% of an LCD monitor can be recycled. All plastics are removed to be recycled into new products. Printed circuit boards can be recovered from LCD recycling and smelted to recover valuable metals, while cabling is stripped to reclaim copper and other metals.

Considering how frequently we get new electronic devices, being smart about LCD recycling can make a huge difference. General Digital encourages all of its customers to recycle their used computer monitors and televisions. Learn more about e-cycling from Maryland’s Department of the Environment, and Maine’s Department of Environmental Protection.

It might come off as a surprise but about 98% of an LCD/monitor can be recycled to extract useful material including plastic, copper, and other metals. The plastic removed from an LCD monitor is used for manufacturing new products while the circuit boards are smelted to extract metals. The wiring in the monitor can also be stripped to extract copper and rubber. All these materials can be recycled instead of getting wasted and polluting the environment. Moreover, some LCDs and monitors can be refurbished to be used again by extending their lifecycle. Only an expert in electronic recycling can do this through a meticulous process.

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 ScreensLCD is short for liquid crystal display.Due to the amount of space an LCD screen can save, it has become one of the leading options for computer monitors.This space is saved because LCD"s use two sheets of polarizing material with a liquid crystal solution between them rather than bulky vacuum tubes. In order to create the pictures you view on a computer monitor, an electric current is passed through the liquid crystals, which causes each of the crystals to align so that light cannot pass through them. These "shutters" can be controlled to create vivid images.

A CRT, or cathode-ray tube, is another type of screen. It works by moving an electron beam across the back of the computer monitor screen. As the beam moves along the screen, it lights up the thousands of phosphor dots that are inside of the glass tube, thus illuminating portions of the screen. By creating many lines across the back of the screen, it creates an entire screen filled with colorful pictures. However, these screens are larger and heavier than LCD"s. They are also a larger threat to the environment. CRTs can contain cadmium, a toxic substance, in its phosphors. The back part of the CRT can contain leaded glass, another dangerous substance.

The circuit board is located inside the plastic casing of the computer monitor and controls all of the computer monitor"s functions.It is made from many mined materials such as gold, copper, lead, nickel, zinc, beryllium, tantalum, coltan, silver, and other materials that conduct electricity.Manufacturing of circuit boards requires the use of crude oil to make the plastic and sand and limestone to create fiberglass.Tantalum is often used as one of the materials in circuit boards as it conducts electricity well.Many of the materials used in circuitboards are non-renewable and can remain in theenvironment for a large amount of time.

The plastic casing of a monitor is intended to protect all of the electrical, internal parts.  All plastic is created by combining natural gases and crude oil. Both are non-renewable sources that take millions of years to form again.

Innocent deaths, environmental damage, and the current use of coltan can all be reduced; and you can make a difference. All you need to do is recycle your old electronics such as computer monitors, cell phones, gameconsoles, TVs, cameras, etc. Click here to get more information about recycling centers near you.

One of the largest recycling problems faced by most countries comes down to the sheer volume of computer electronics that are obsolete and outdated. With technology advances showing no signs of slowing down, it"s no wonder that businesses and home users are constantly upgrading computer monitors.

The first thing that"s important to understand is how big of a problem electronics are. With people replacing phones every year and computers every few years, it shouldn"t come as a surprise that there are mountains of discarded electronics every year.

When e-waste like monitors isn"t properly handled at the end of its life, then exposure to the natural elements alone can cause many of the toxic materials to break down and evaporate into the air.

But even modern LCD monitors contain many different metals and chemicals that are perfectly safe when they are contained. But even small amounts of them in the open air canseriously damage animals, plants, and humans.

When monitors and other computer electronics are illegally dumped, or they end up at a landfill, then all those metals like lead, mercury, and cadmium can ultimately release due to heat, cold, and moisture exposure.

These are not problems that arise suddenly, and contamination often happens over many years with a gradual accumulation of the toxins. Once there are symptoms, a lot of the damage has often been done, and people can be left with permanent health problems.

OK, now that you know that those old monitors in the garage or basement could be a health hazard and that the right thing to do is to recycle computer monitors, it"s time to go through this simple process.

If there are loose cables still attached, or the monitor is still attached to a computer, then make sure you remove all the cables first. You can recycle these as well, but it"s best to keep them separate.

Now is also a good time to check for any other electronic devices like printers, scanners, and DVD players that are just taking up space and never used.

Make sure that your old computer monitors are safely placed in your trunk so that they avoid falling or rolling around. Those external plastics won"t stand up to much force, and you can quickly damage internal components that contain the heavy metals.

If you live in the San Francisco Bay Area, then you can bring your old e-waste to the GreenCitizen recycling facility. The company has years of experience in recycling electronic devices and offers competitive rates.

The recycling process for computers and monitors starts with carefully taking apart the electronics into their individual components. There are plenty of plastics, and then there"s the glass and multiple circuit boards.

While some materials in these devices can enter the cycle economy, there are others like lead glass that can"t be reused. These need to be separated and then disposed of at specialist sites using containers that make sure they are sealed indefinitely or until there"s a solution for dealing with it better.

While they might not take care of the overall breakdown of the materials, many of them do offer to take back old computer monitors, printers, hard drives, phones, and laptops for free or a nominal fee.

Many major electronics stores now offer a recycling program where you can drop off computers, laptops, TVs, monitors, and anything electrical that you bought there.

This should be your first option if you have computer monitors that are relatively modern and still in working order. Many charities and Goodwill stores will happily accept electronics that could help out people with little financial means.

Reusing electronics as is without refurbishing or recycling is an ideal choice, especially since there are so many people that can"t afford the latest and greatest in modern technology.

If you"re in the San Francisco Bay Area and have some old monitors from personal home use, then GreenCitizen offers a free drop-off service . And the process couldn"t be any easier.

Then weigh the fee items and fill out the mail-in recycling form. All that"s left is to pay the fee online and receive the shipping instructions. You can then use your preferred shipping company to have your old computer monitors and other equipment sent to the recycling center.

GreenCitizen has created a Green Directoryof recycling service providers around the country with an easy-to-use search function. You simply enter what you need to recycle and what your zip code is, and you"ll receive the nearest company that offers a business collection or drop-off program.

Yes, old CRT monitors can be recycled. In most cases, it"s not possible to reuse them with modern computers, but they contain toxic metals that should end up in the trash or landfill.

The penalty for not recycling old computer monitors is different from state to state and county to county. In many cases, it ranges from $50 to several hundred dollars, which should be enough incentive not to throw it in the trash.

Yes, a monitor can store data. This is typically more common with smart TVs, but some monitors also have similar functions that could store login details for streaming services. It"s important that you use a data destruction service for such devices.

The easiest way to get rid of working electronics for free is to drop them off at Goodwill or a charity store. If they are relatively new, then you may also be able to recycle them for free at a local recycling center.

I strongly suggest starting your recycling effort with GreenCitizen, and even if they aren"t close enough to deal with your old computer screen, laptop, or other devices, our Green Directory will be able to point you to your closest service.

So, your old computer monitor has finally taken permanent turn for the worst and is now ready for disposal. What to do? Well, there may be a number of beneficial ways to dispose of an old computer monitor: recycling, donating and repurposing spare parts are options, but there are also a number of choices to avoid. In fact, simply tossing your old monitor could be hazardous, and in some cases, illegal.

That’s because, in order to work properly, many computer monitors contain chemicals that are harmful to the environment if released. For instance, LCD monitors produce visible light by sending electrical impulses to the mercury contained within them. Manufacturers continue to use the dangerous liquid since few other sources possess the qualities necessary to produce this desired effect.

Yet another factor regarding disposal is the increasing speed with which computer monitors and electronic devices containing hazardous wastes are being discarded. In 2005, the average lifespan for a computer monitor had shortened to about two years, down from the five years reported in 1992. Shorter lifespans keep consumers on the lookout for new monitors.

As consumers continue to seek out newer styles or the latest technological upgrade, turnover rates have increased. This, in turn, means an increased number of computer monitors destined for disposal on an almost yearly basis.

This also means it is crucial for consumers to have a working knowledge of both the environmental risks, and in some states, the legal risks of improperly disposing old computer monitors. Luckily, a number of e-recycling services are well versed in the best methods of disposal available today and can assist with recycling monitors safely.

Computer monitors, like so many electronic devices can sometimes contain a number of dangerous chemicals. Disposal can cause a release of toxins into the air, ground water or soil. When hazardous electronics are disposed near lakes and streams, the water often becomes contaminated.

Thus, it is important to know which monitors are hazardous and why. The standards for this assessment are usually specified in country-specific regulations imposed by governmental bodies such as the Environmental Protection Agency here in the U.S.

According to the EPA, an electronic device is considered hazardous under a number of complex circumstances. Hazardous waste belongs to a special EPA category unto itself and has special rules attached to disposal. The regulations for disposal of hazardous wastes may vary from state to state.

Electronic devices can be deemed hazardous for a number of reasons — mainly their contents. Computer monitors, in particular, are susceptible to a hazardous waste categorization. Typically, the older a monitor, the more likely it contains hazardous components.

For instance, both old and new monitor models tend to contain mercury, as mentioned. Other chemical contaminants, like cadmium, lithium and harmful flame retardants, can also be found in monitors. In addition, some of the outer shells of monitors can contain phosphorous coatings or be made of PVC plastics.

Knowing the hazardous material contained within computer monitors makes it easy to see that they do not belong in landfills. In most cases, when the monitors remain intact, there is a reduced risk of leakage. However, the possibility of a monitor remaining intact over time in a landfill is extremely slim.

Every one of the chemicals contained in monitors could seep into soil. Contaminated soil eventually works its way into groundwater reservoirs, thereby poisoning water supplies and weakening local ecosystems. Clearly, the effects of landfilling monitors are extremely hazardous and detrimental.

A number of states have taken action to prevent environmental exposure to hazardous chemical found in computer monitors and other electronic devices. Today, 20 states have active e-waste landfill bans in place.

For instance, Illinois, a state that enacted its landfill ban in 2012, bans most electronic devices, including computer monitors from both landfills and incinerators. An incinerator ban on electronics is significant, because electronics contain a number of chemicals that are not harmful until heated. Heating can release toxic gases into the atmosphere. Few other states ban both these types of disposals.

Some states have laws in place beyond the basic landfill ban. In Maryland and Connecticut, laws are in place that require manufacturers to label those electronic devices that contain mercury. Such labeling laws aim to identify electronics containing hazardous wastes, thus increasing the likelihood that these will be disposed properly.

Manufacturers are required to work with recycling centers and state or municipal programs to ensure that e-waste is properly recycled. In some instances, the responsibility also includes regulating the way a device is made. Such requirements urge manufacturers to consider available alternatives to the hazardous chemicals and structural materials traditionally found in computer monitors and other electronic devices.

Due to the environmental hazards and legal issues involved, consumers must keep informed about the most suitable and safe way to dispose of computer monitors. Here is where it is important to know the collection methods in your city or neighborhood and to make sure to keep informed about the requirements at your local recycling center.

Excellent resources for more information about proper disposal in your area can be found at your local chamber of commerce, city hall or community center. Because each community may vary in its response to the need for proper collection and disposal of computer monitors, it is important to inquire first, before disposal, to get the details you will need.

The best way to ensure that tossing your old computer monitor is neither hazardous nor illegal is to find a electronics recycling service capable of properly handling electronic devices. The recycler can help with collecting and recycling the device in a way that both complies with state and federal guidelines and protects the environment.

In California, it is illegal to put electronic equipment in the trash. Many electronic devices contain toxic chemicals that can leak from the landfill and contaminate groundwater and soil. Electronic devices are those that have a circuit board and/or LCD screen.

Please note that the HHW facilities will recycle and/or safely dispose of all accepted electronics, small appliances, and electrical items that are dropped off, but they do not repair, refurbish, or donate working electronics. For the highest and best use, please consider repairing broken items or donating working electronics for reuse rather than disposing of them. For more information, check out our Re:Source guide.

Small "electrical" appliances that have a plug but no computer chip or LCD screen are not hazardous waste. Find repair and reuse options for small appliances (working and non-working) in RE:Source Guide.
