The Circular Economy is an alternative to the traditional linear economy (take-make-dispose). Its core principle (2) is to keep resources in use for as long as possible, extracting maximum value from them whilst in use, and then recovering and regenerating products and materials at the end of each service life through processes like reuse, repair, and recycling to minimize waste. Reducing the need for virgin materials indirectly contributes to reducing the use of fossil fuels (1), which are used both as materials and in energy- intensive production processes.
