Products often end up in landfills after serving their purpose, e.g. after their end-of-life. While some parts can be/sometimes are salvaged for valuable materials like rare earth elements, the majority are discarded-a common but wasteful practice. The concept of circular economy promotes recycling or recovering to maximize resource efficiency and to avoid landfill from end-of-life products, though often sub-optimally. Our method introduces a simple, yet novel, concept grounded in circular economy principles to extend the lifespan of end-of-life products' components. The product is disassembled, and components are grouped based on their susceptibility to wear and tear. Using a 360° visual diagnostic tool, individual components are then categorized as either healthy with reduced remaining-useful-life or having reached end-of-life. Appropriate R-strategies such as reuse, repurpose, refurbish, remanufacture, recycle, and recover are subsequently applied, extending the lifespan of the component. The proof-of-concept for the 360° visual diagnostic tool is validated using a product from a Swedish outdoor power product manufacturer.•Focus on end-of-life products not originally designed with circular economy principles.•Expands R-strategies from recycle and recover to reuse, repurpose, refurbish, remanufacture, recycle and recover for end-of-life products.•Provides practitioners with a decision-making tool to estimate component-level circularity and identify end-of-life strategies.
产品在达到使用目的后，例如在其使用寿命结束后，往往最终被填埋。虽然有些部件可以/有时确实会被回收以获取稀土元素等有价值的材料，但大多数都被丢弃了——这是一种常见但浪费的做法。循环经济的理念提倡回收或再利用，以最大限度地提高资源效率，并避免使用寿命结束的产品被填埋，尽管往往效果不尽如人意。我们的方法引入了一个基于循环经济原则的简单而新颖的概念，以延长使用寿命结束产品部件的寿命。产品被拆解，部件根据其易损程度进行分组。然后使用360°视觉诊断工具，将各个部件分类为仍有一定剩余使用寿命的健康部件或已达到使用寿命结束的部件。随后应用适当的R策略，如再利用、重新利用、翻新、再制造、回收和再回收，以延长部件的寿命。使用一家瑞典户外动力产品制造商的产品对360°视觉诊断工具的概念验证进行了验证。
•关注最初并非按照循环经济原则设计的使用寿命结束产品。
•将R策略从回收和再回收扩展到使用寿命结束产品的再利用、重新利用、翻新、再制造、回收和再回收。
•为从业者提供一个决策工具，以估计部件层面的循环性并确定使用寿命结束策略。
