At GreensafeIT Recycling Computer Monitors is part of our core services. Monitors are classed as Hazardous waste so needed to be treated in-line with hazardous waste regulations at all times.

Recycling Computer Monitors

Computer Recycling Monitor 

Despite TFT screens being around for years it is still surprising how many CRT monitors are being disposed of in the UK today. We have defined processes in place to ensure the remaining devices are handled and controlled as hazardous waste and not resold into 3rd world markets where they will become a serious health risk in coming years. We ensure all CRT’s are environmentally disposed of at all time.

Environmentally responsible

Our continued investment into specialist facilities, plant and processes ensures that we recover and recycle the hazardous cathode ray tubes (CRTs) responsibly and in an environmentally friendly manner.  Our commitment to compliance and standards provides you with the peace of mind that all your hazardous waste is being dealt with in an environmentally friendly manner.

Maximum recovery

Our advanced Recycling Computer Monitor and TV facilities enable the glass in the screens to be recycled and used in the manufacture of new televisions and monitors. Other materials such as ferrous metals and non-ferrous metals are recovered for recycling too.

 How Recycling Computer Monitors (CRT (cathode ray tube)) is done ?

The recycling process begins with consumer or companies bringing the CRT to an electronic Computer recycling Centres. Next the CRTs are shipped out of the collection center to the recycling plant for further processing. Unfortunately many electronic collectors ship CRT Over Seas where they are often dumped. If you choose an electronic recycler with the ADISA certification you can be confident that it will be properly recycled in the United Kingdom

When the CRT(cathode ray tube) monitor begins the dismantling process the plastic casing of the monitor is removed. This is done manually, exposing the panel glass, glass tube, electronic chip boards, wiring and electron gun. The electron gun contains the cathode and anode units. The cathodes are heated filaments which produce a stream of electrons. The positive charge of the anode draws the electrons from the cathode’s copper components and directs the electrons to create the image. All of these parts contains different materials that are removed and sorted into separate bins to undergo their own recycling process.

Within the glass tube is a vacuum seal, so to prevent the unit from imploding specialized equipment needed to dismantle it. Inside the glass is a phosphorus coating which glows when it is hit by light. This phosphorous is removed so the glass can be recycled. The glass used in the tube generally contains 20% lead by weight. Adding lead to glass is a common practice to improve optical quality and creates a shield against the radiation produced by the electrons. The lead glass needs to undergo a lead smelting process and can be used to make new CRT monitors.

Once the plastics, electronic gun, glass tube, motherboards, wires and other miscellaneous parts have been separated they all undergo the separation process. They are crushed, vibrated, shredded or sprayed by a strong current of water to separate the different materials. Once they have been separated strong magnets with specific electronic charges for each different metal are used to separate the different metals, such as copper, gold, iron, and steel.

After these parts are separated they are often sold to different processors where they will be further refined, then sold production of new materials. This process will reduce the impacts of mining and ensures toxins are not sent to landfill.
