Small changes for sustainable future, but big differences. Many people are shocked by the rapid increase of plastic waste after the coronavirus pandemic. As we all know, sustainable future is not an option, it is essential to survival. What if we could make a car out of waste such as plastic? In order to change the material of a vehicle, it is necessary to design a vehicle in a new-shaped language rather than the modeling and construction method used to make the existing vehicle. Vehicles using new materials can be reused almost completely or used for other purposes even after they are used up. In addition, this new shaped cars are functionally easy to apply to various applications. Because it can be used with multiple functions, the number of vehicles to be manufactured can be reduced, and a sustainable product life circle can be formed.
