Elevated Wetlands by Noel Harding. These giant polystyrene, tooth or animal shaped containers are functional wetlands that use on-site solar panels to pump water from the Don River through the basins. The water is cleaned by wetland plants (which have the innate biological capacity to remove pollutants from water) anchored in ‘fluff’ (an alternative to soil, made from shredded automobile plastic waste).
The Elevated Wetlands in Taylor Creek Park, Toronto, Ontario. Known as "the Teeth", the Elevated Wetlands are an art installation, created by an artist named Noel Harding. They were commissioned by the Canadian Plastics Industry Association and are made entirely from recycled plastics. Powered by solar panels, the devices cleanse polluted water from the Don River.
