The Circular Economy is one of the strategic sustainability tools to reduce the extraction and consumption of natural raw materials and is an alternative to the current linear model (extract raw materials, produce, use and throw away). This system already comes into play when designing an object from the perspective of its life cycle (Life Cycle Assessment, LCA) in order to maximise the reuse of its components. Suffice it to say that more than 2.5 billion tonnes of waste are produced every year in the European Union alone. The Circular Economy is a model not only of production, but also of consumption, involving sharing, lending, reusing, repairing and reconditioning. Its aim is to extend the life cycle of products, helping to minimise waste. Given the moral obligation and selfish interest in continuing to live on Earth, it is necessary to think in terms of the protection of natural raw materials and not only the recycling of production waste, but also the end-of-life of products, which must be designed and manufactured in such a way that they have as little impact as possible even when they are discarded.
