O-Trash² is a collection of bioleather bags made of organic food waste and tapioca starch biopolymer. Those circular bags are versatile, cheap, easy to produce, 100% biodegradable and compostable. They take about one week to decompose in nature.
This bag collection was strongly inspired by the cradle-to-cradle design concept of the chemist Michael Braungart and the architect William McDonough : «cradle-to-cradle design is based on the closed loop nutrient cycles of nature, in which there is no waste.(...) One organism's waste is food for another, and nutrients and energy flow perpetually in closed loop cycles of growth, decay and rebirth. Waste equals food.».
Food waste and tapioca starch are used as sustainable raw materials. The transformation and production of the O-Trash² collection consume very little energy. The design process is thought with a biomimetic approach to enrich our ecosystem. The lifetime of the product creates a positive feedback energy loop. At the end of the product life cycle, the user can throw the used bag product into the organic trash to go back to its original shape.
The O-trash² bag collection is not only a design project, it is an artistic statement. The goal of this project is to demonstrate the value of our daily trash and encourage the re-use of it as a raw material in product manufacturing.
