Adding cigarette waste could cut the energy required to fire bricks by up to 58 percent

Researchers from RMIT University in Australia have demonstrated how bricks made with cigarette butts can slash energy consumption and provide a solution to this type of waste. They discovered that repurposing butts by incorporating them into fired-clay bricks for building could cut the energy needed to fire bricks by as much as 58 percent.

Recycling discarded cigarettes provides a sustainable way to solve a global littering problem, offsetting the waste from butts that are tossed on the ground. Millions of tons are currently dumped into the environment, with poor biodegradability and heavy metals such as arsenic, chromium, nickel and cadmium in the filters that get into soil and waterways and can contaminate them.
