Cradle-to-cradle employs a design and production perspective on circular economy.
The cradle-to-cradle perspective emphasizes the extended design and production responsibility in the circular economy: The producer is responsible for ensuring that all constituents and byproducts re-enter the circular loop.
It captures the idea that products need to be designed and produced in a way that allows all constituents and all byproducts to preserve value, until they are ready to be incorporated into a new context. This corresponds to a full cycle in the circular economy.
This is orthogonal to the very unethical take-make-dispose thinking prevalent in the linear economy.
