Japanese university students have converted cigarette butts into T-shirts, it has emerged.
Shinji Sawai, 21, a student at the College of Economics of Ritsumeikan University came upon this idea when he saw huge quantities of cigarette butts at his local station everyday.
He formed a group called AOI with other university students who collected cigarette butts from places like local gas stations.
After employing a technique developed by scientists to reduce harmful toxins, the threads are then woven into a fabric before being used to make T-shirts, according to the Japanese newspaper Asahi Shimbun.
"The end result is a fabric which is well-ventilated and highly absorbent with a slightly uneven surface and varying thickness levels," the Telegraph quoted Mr Sawai as telling the paper.
The students recently modelled the cigarette butt T-shirts at a fashion show at the National Cultural Festival of Kyoto.
