The concept that refers to a system where materials are continuously reused and waste is eliminated is indeed "Cradle to cradle." This approach focuses on designing products and systems that are regenerative by nature. In a cradle-to-cradle framework, materials are intended for continuous cycles of use, ideally returning to the earth as non-toxic nutrients or being repurposed into new products without loss of quality. This principle contrasts with the traditional "cradle to grave" model, which often leads to waste at the end of a product's life.

Lifecycle assessment evaluates the environmental impacts associated with all the stages of a product's life, but it does not specifically address the continuous reuse aspect. Downstream activities typically refer to processes related to the distribution and sale of products rather than the systems involved in material reuse. Systems thinking is a broader approach to understanding complex interactions within a system but does not explicitly focus on material reuse in the way that cradle to cradle does.
