Integrated recycling and waste management solutions under one roof and achieve 94% recycle rate How can Concept Management help?Ĭoncept provide tailored reporting requirements suited to your business needs with full waste auditing services They also lead the way in Flat Panel Display (FPD) recycling, raising the standard for British hazardous waste recycling once more. Fully trained operators use their expertise to create a closed-loop recycling solution and offer: Other materials, such as ferrous and non-ferrous metals, are also recovered for recycling, and every step of the dismantling process is conducted in full accordance with all relevant UK and EU safety legislation.

These investments enable our experts to recycle the glass found in TV screens and computer monitors in a closed-loop solution, and to manufacture new products from the recyclate. Our partner for the disposal of CRTs has made major investments in the recycling of hazardous substances and material commodities from Cathode Ray Tubes (CRTs), found in televisions and computer monitors. The potential to use waste glass, including cathode ray tube (CRT) glass, for making new products or as an admixture to existing ones is being intensively investigated. Mercury, Lithium, Cadmium, Phosphors, Lead and means that they should be treated as hazardous waste. This means that recycling CRTs is a specialist recycling process because the CRTs contain several nasties. Landfilling is no longer the cheapest alternative. Why should you recycle a Cathode Ray Tube? Normal disposal methods for CRTs have been landfilling and incineration because of their low recyclable value. As a matter of safety, the face is typically made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions, particularly if the CRT is used in a consumer product.
long from front screen face to rear end), fairly heavy, and relatively fragile. The CRT uses an evacuated glass envelope which is large, deep (i.e. It has a means to accelerate and deflect an electron beam onto the screen to create images. The cathode ray tube (CRT) is a vacuum tube containing one or more electron guns, and a phosphorescent screen used to view images.

After treatment, more than 90% of the sodium in the oxide phase was extracted in water.
The optimum temperature and treatment time for increasing the leachability were 700☌ and 2h, respectively. In this document, the Council recommended streamlined regulatory requirements for CRTs to encourage recycling and better management.
A reductive atmosphere promoted the phase separation and crystallization, and the leachability of sodium from the oxide phase was enhanced. In 1998, the CSI Council issued a document titled Recommendation on Cathode Ray Tube (CRT) Glass-to-Glass Recycling. In this study, the phase separation of sodium and the crystallization of water-soluble sodium silicates were induced after the reduction-melting process to enhance the leachability of sodium in the oxide phase and to extract the sodium from the phase for the recovery of Na2CO3 as flux. THEBirken-head-based Global Environmental Recycling Company, which has developed a process to reclaim and recycle the highly toxic glass from cathode ray tubes for the TV manufacturing industry, has made the finals of the Electrical & Electronics Recycler of the Year awards being announced on November 14. To reduce flux cost, a technique to recover added flux from the generated oxide phase is also important in order to recycle the flux recovered from the reduction-melting process. With large quantity of flux (Na2CO3), lead can be recovered from the funnel glass of waste cathode-ray tubes via reduction-melting at 1000☌.
