Researchers have shown how industries could work together to recycle cigarette butts into bricks, in a step-by-step implementation plan for saving energy and solving a global littering problem.
Over 6 trillion cigarettes are produced each year globally, resulting in 1.2 million tonnes of toxic waste dumped into the environment.
RMIT University researchers have previously shown fired-clay bricks with 1% recycled cigarette butt content are as strong as normal bricks and use less energy to produce.
Their analysis showed if just 2.5% of global annual brick production incorporated 1% cigarette butts, this would offset total cigarette production each year.
The research team has now developed a detailed plan for bringing the brickmaking and waste management industries together, to implement cigarette butt recycling into bricks at mass scale.
