Making materials consumes about 21% of the global energy demand; concerning metals production, it accounts for about 8% of total global energy consumption. Circular economy strategies such as longer life, more intense use, repair, product upgrades, modularity, remanufacturing, component reuse, and open/closed-loop recycling are strategies to put in place urgently to reduce the environmental impact of raw material production. Although recycling of metals is the most used strategy and is being improved in terms of efficiency, it is mandatory moving towards more virtuous circular economy strategies, such as product/component reuse. In this paper a novel reuse strategy for sheet metal based End-of-life components is proposed; to be more specific the suitability of Single Point Incremental Forming (SPIF) to reshape End-of-life aluminum components is presented. An experimental approach is used to change the shape of a square box, previously obtained by deep-drawing processes, by means of single point incremental forming processes.

The paper aims at outlining the environmental impact of the proposed reshaping approach presenting a Cumulative Energy Demand and CO₂-eq. emissions comparative analysis. Three different routes are analyzed and compared to one another: SPIF based reshaping, conventional recycling and Solid State Recycling (SSR) routes. The SPIF based approach proved to be the most environmentally friendly strategy, the energy and emissions saving are ascribable to the fewer process steps and the less material involved with respect to the analyzed recycling strategies.

制作材料消耗了全球能源需求的约21％；在金属生产方面，它约占全球能源总消耗的8％。诸如延长寿命，更频繁地使用，维修，产品升级，模块化，再制造，部件重复使用以及开环/闭环回收等循环经济策略是迫切需要采取的降低原材料生产对环境影响的策略。尽管金属回收是最常用的策略，并且在效率方面正在得到改善，但它是强制性的，朝着更良性的循环经济策略迈进，例如产品/组件的再利用。本文提出了一种新的基于板材寿命报废组件的重用策略。更具体地讲，提出了单点增量成形（SPIF）重塑报废铝部件的适用性。实验方法是通过单点增量成形工艺来更改以前通过深冲工艺获得的方盒的形状。

本文旨在概述提出的累积能源需求和CO ₂当量的重塑方法对环境的影响。排放比较分析。分析并比较了三种不同的路线：基于SPIF的整形，常规回收和固态回收（SSR）路线。基于SPIF的方法被证明是最环保的策略，与分析的回收策略相比，节能和减排归因于更少的工艺步骤和更少的材料。
