Recycling is vital for sustainable management of metal resources. While closed-loop recycling is desirable, open loop recycling is more common due to the mixing of different metal-species in the end of life process. This is associated with losses in quality, and additional environmental burdens such as GHG emissions, as well. A tool was developed that makes possible to estimate the environmental burdens associated with these quality losses. Application to ferrous materials used in passenger cars showed the significance of improvement in end-of-life separation technologies in mitigating the nation-wide GHG emissions. Furthermore, a mathematical model was developed that is capable of tracing the fate of materials over time across products under explicit consideration of products lives, recovery, refining, and use.

回收利用对金属资源的可持续管理至关重要。虽然闭环回收是可取的，但开环回收更常见，因为在生命结束过程中混合了不同的金属种类。这与质量损失以及温室气体排放等额外的环境负担有关。开发了一种工具，可以估计与这些质量损失有关的环境负担。乘用车铁材料的应用表明，报废分离技术的改进对减少全国范围内的温室气体排放具有重要意义。此外，开发了一个数学模型，能够在明确考虑产品寿命、回收、精炼和使用的情况下，追踪材料随时间的变化。
