From an article about the possibility of including cigarette butts in making bricks and asphalt:
Most importantly, both the bricks and the asphalt imprisoned the cigarettes’ toxic chemicals and prevented them from poisoning their surroundings.
“This research shows that you can create a new construction material while ridding the environment of a huge waste problem,” Mohajerani said.
Well… not so much “ridding” as “postponing until the brick & asphalt get torn up and thrown into a landfill”.
At least they are not calling for throwing smokers into cornerstones of buildings, for now.
I read the paper and then looked up RMIT University on their website. As it turns out, RMIT is apparently the #14th ranked university in Australia. So I wonder: Is that at the bottom or second from the bottom?
