• Panasonic using laser for recycling of old TV sets

    Panasonic is now using lasers that can quickly weaken the thick glass of the cathode ray tubes of old televisions and increase the processing speed by three-folds. The cathode ray tubes in old TVs are made of different glasses in the screen at the front and also at the end of the funnel at the back. Till recently, Panasonic was using hot wire around the edge of the tube for weakening such thick glasses. This technology processed 24 sets in an hour. To increase this time was a big challenge because it took some time for the wire to heat up and cut the glass into two. So Panasonic started using lasers. Here the CRT is rotated so that the powerful laser runs across all four sides of the tube which creates a stress crack. After that all you need is a gentle tap with a tool and bingo! It’s into two pieces. The new method increased the processing rate from 24 to 72 sets an hour.
