Tomorrow is the International Day of the Environment. For this, I would like to take a look at a special innovation - the Manta. A boat that not only collects plastic in the ocean, but also uses it to power itself.

Today is International Environment Day. Under the motto "Together for the environment and climate - avoiding plastic waste", innovators, researchers and companies from a wide range of industries are taking up the challenge and working to make our world a little bit better. Four environmental innovations of the last years.
