French architecture firm Chartier-Corbasson has hopped on the green-building train with their recently unveiled green skyscraper concept. Renderings of the Organic London Skyscraper show a towering, pyramid-shaped building comprised of panels made from recycled plastic material. But this tower takes a radical twist—it would be built from the trash of its inhabitants and grow over time.

Designers have unveiled a bevy of such radical green buildings have recently seen a sharp rise in popularity and demand, whether they take the form of skyscrapers or floating islands. One such project, Hy-Fi, a green structure that just debuted at New York City’s MoMA PS1, is be built with bricks made from corn stalks and roots. Following this trend, Chartier-Corbasson has provided their own plan for a green supertall building.

The Organic Skyscraper’s usage of recycled plastics as a building material would hypothetically reduce building costs and make building maintenance relatively simple as well. The proposed tower collects recyclable waste from building tenants and the then forms panels from the waste with which to grow taller.

The structure of the building is influenced by bamboo scaffolding commonly seen in areas of Asia, but with a slight twist. The scaffolding will remain once construction is completed as a part of the building. These scaffolds consist of hollow tubes and serve a dual purpose: to provide wind resistance and to generate electricity for the building via small wind turbines incorporated into the design. An elevator could possibly be powered by the electricity generated from these turbines.
