From Cigarette Butt to High-Performance Super capacitor

Cigarette butts are an eye-sore and whether disposed of in ash trays or thrown away on the street they all need to be dealt with. There must be billions discarded across the globe every year and they have to be disposed of correctly to avoid threats to the environment from the nasty chemicals such as lead and arsenic which could seep into the water table.

Well Scientists at Seoul National University may have an ingenious solution. Using a method called pyrolysis they indented to turn the cellulose acetate fibers that make up the filter into a carbon based material that they believe could be used as a high-performing component for super capacitors.

This could lead to better energy storage for everything from mobile phones to wind turbines. You can read the full article here.
