Since the Industrial Revolution, our economy has followed a linear path, based on the principle “take, make, use, dispose”. However, the climate change, the depletion of natural resources, and biodiversity loss caused by this system have highlighted its unsustainability and the need for new systems of growth. The term circular economy has emerged from the debate as a new model of sustainable growth in which the life cycle of resources and products is extended, minimizing the waste production. The transition to a circular economy shifts the focus to avoidance, reuse, repair, renewed and recycling practices. From this perspective what used to be considered as waste can be transformed into a resource.
