Resumo:
Nowadays, the strong environmental, social and economic appeal faced by the industrial sector have been contributing to the development of studies and research aimed at finding alternatives to the use of solid waste generated in its processes, in order to add value to them and to minimize the amount of waste sent to landfills, promoting improvement in the environmental performance of their processes and still favoring their image in the market, especially in the international market. In this way the Circular Economy arises. According to Ellen MacArthur Foundation (2013), the Circular Economy is restorative and regenerative by principle, arises precisely to put an end to the current linear industrial model, considered as pipe end, in which, the raw material extracted from nature is processed, consumed and discarded after use. The goal of Circular Economy is to keep products, components and materials at their highest level of usefulness and value, all the time. The model distinguishes between technical and biological cycles. Consumption happens only in biological cycles, where food and biologically-based materials (such as cotton or wood) are designed to feed back into the system through processes like composting and anaerobic digestion. These cycles regenerate living systems, such as soil, which provide renewable resources for the economy. Technical cycles recover and restore products, components, and materials through strategies like reuse, repair, remanufacture or (in the last resort) recycling (Ellen MacArthur Foundation (2013). The circular economy incorporates ideas from different schools of thought as the regenerative design, cradle to cradle, industrial ecology, economy of performance, biomimicry, and the blue economy; This model of economy is based on three principles: nature as model, nature as a measure and nature as a mentor.
