Turn grey into green, simply with a flip of a tile! With these ‘100% duckweed & perennial seed mix’ tiles everyone can easily contribute to greenifying our cities. These tiles are made of duckweed, a high potential natural waste stream. Duckweed is a water plant that contains a large number of nutrients like nitrogen and proteins. Ideal for plant growth. Therefore, a perennial flower seed mixture is integrated into the tiles. Over time, the tiles will decompose and release their nutrients to the flower seeds, allowing for the growth of a beautiful flower bed. By adding more green to cities through these tiles, biodiversity will increase and flooding risk and heat stress will decrease.
