What can TV material do in medical field?
February 26, 2010
News Worldwide — The Current events technology reveals that old televisions can be recycled and used in medical field. The chemical compound polyvinyl-alcohol also called PVA is largely used in industry as a main element of television sets that have liquid crystal display or LCD technology. When these television sets are discarded, the liquid crystal display (LCD) panels are incinerated in landfill sites.
For adding up in the current events technology, Scientists have now invented a way of reusing PVA from television screens and converting it into a material suitable for the usage in tissue scaffolds that aid in the regeneration of body parts. This substance can also be used in pills and dressings that are made to transport drugs to certain parts of the body.
Professor James Clark said that with 2.5 billion LCDs that are near to discarding and the consumption of huge amount of new LCDs can become a big potential waste to use. “It is important that we find ways of recycling as many elements of LCDs as possible so we don’t simply have to resort to burying and burning them…The researchers have developed a technique where recovered material is heated in water in a microwave and washed in ethanol to produced expanded PVA”. He added.
