A French actor and a self-taught inventor have designed a low-tech machine that converts plastic waste into diesel and gasoline, which they say could help fight pollution and provide fuel for remote communities in developing countries.
Proponents of plastics-to-fuel technology say the sector could be worth hundreds of millions of dollars in the next five years, and that by melting plastics into fuel they are providing a solution to the planet's plastic waste crisis.
Opponents worry that the process creates harmful fumes.
