The Planet Budapest 2021 sustainability expo is aiming to ensure that the quality of life of younger generations will be “at least on par” with today’s standards, President János Áder told public radio. The event running through Sunday at the Budapest expo grounds features several inventions of young people contributing to a sustainable future, Áder told Petőfi Radio. He cited a composting robot and a water-economic car wash system as examples. Áder warned of the ever growing “throw-away society”, and called on listeners to rethink their consumption habits. According to a UN survey, one-third of clothes purchased is not worn more than once, he said.
