Sustainability, and especially Circular Economy, focuses on ‘closing the loop’ of material production, to avoid waste and optimize usage (Ellen MacArthur Foundation, 2012). Reduce and Reuse are the most effective methods of sustainability, the smaller the ‘recycle-circle’, the more sustainable and easier to control the material flow is.

 

循環經濟在永續發展中特別強調物質的封閉循環，避免浪費與最佳化的利用(Ellen MacArthur Foundation, 2012)。減少生產與物品再利用是永續發展最有效率的方式，越小的回收循環更容易達到永續利用與物質循環的控制。
