Today I had to change electric bulb in bathroom and my 13 yr old son Vinayak asked me that can we recycle the electric bulb or not. With my limited knowledge, I replied him that due to vacuum inside bulb, it may not be possible. But he questioned that can we not create vacuum as well.
I think it can be a good business proposition to recycle electric bulbs if it can be done as cottage industry in small towns and villages. Lot of bulbs get fused in India due to fluctuation in voltage and other reasons. It may reduce costs and save the environment as well.
