A vision for a sustainable future
GXN designed a sustainable bus shelter based on the Cradle to Cradle principles that focuses on easy production, easy maintenance, and beneficial contributions to the environment. The utilization of bio-composites and its active surfaces makes this a healthy and practical addition to any city.
Cradle to Cradle
The Cradle to Cradle approach to design is modeled after the natural world in which one organism’s waste is benefitial to the rest of the ecosystem. By the same principle, materials should never become waste that cause buildups in our landfills but it should continue to have a lifecycle for other generations of products, raw materials, and healthy living organisms.
Using Natural Materials to Build
Biocomposite is a term for a fibre reinforced polymer comprising of natural fibres in a polymer matrix, in this case flax fibers are bonded with bio-resin. The structure of the bus shelter is stiffened by a honeycomb structure embedded between the surfaces. Bio-composite is an impact resistant material due to the natural fibers flexible characteristic. Its mechanical properties are comparable to glassfibers but the embodied energy of bio-composites is 50% less than glassfibers. In addition, bio-composites will not incur disposal fees when its lifecycle ends as it can continue to be used for other projects.
The bus shelter also has active surfaces which contribute to a healthier environment. These two main features contribute to a sustainable bus shelter that can clean the same amount of air as 20m2 of green area in the middle of Copenhagen. This means that the bus shelter is cleaning the pollution produced by 270 cars per day.
