Chalk up another plus for concrete's versatility: One of the exhibitors for this year’s show at the Milan Design Week is Hungarian designer concrete firm IVANKA, which will be presenting The Water of Life, a project allowing houses to turn rain into high-quality drinking water by filtering it through a bio concrete system. The new technology makes use of concrete rooftops, surfaces and cisterns developed to collect rain, with a special concrete that is enhanced with a filtering function and pH neutral orientation to create the new water management system.
