Fluorinated greenhouse gases (F-gases) are used for various applications, such as in refrigeration and air conditioning, as substitutes of the ozone-depleting substances. Their utilization has increased drastically over the last few decades, with serious consequences for global warming. The Kigali Amendment to the Montreal Protocol and several national and international legislations, such as the 2014 EU F-gas Regulation, aim to control the utilization and emissions of these gases. In the EU, the phase-down of hydrofluorocarbons (HFCs) is underway, with successive reductions in quotas up to 2050. Under this scenario, efficient strategies for managing the produced and already existing F-gases are of vital importance to guarantee that their effect on the environment is mitigated. Up to now, most of the F-gases recovered from end-of-life equipment or when retrofitting systems are either released into the atmosphere or destroyed. However, in order to put forward a cost-efficient adaptation to the F-gas phase-down, increasing separation and recycling efforts must be made. This critical review aims at providing a revision of the current F-gas management problems and strategies and providing an overview on the innovative strategies that can be applied to contribute to build a sustainable market under circular economy principles.

减轻氟化温室气体对气候变化影响的废物管理策略

氟化温室气体（F气）可作为各种消耗臭氧物质的替代品，例如在制冷和空调中使用。在过去的几十年中，它们的利用急剧增加，对全球变暖产生了严重的后果。《蒙特利尔议定书》的《基加利修正案》和一些国内和国际法规，例如2014年《欧盟F气体法规》，旨在控制这些气体的利用和排放。在欧盟，氢氟碳化合物（HFC）的逐步淘汰正在进行中，到2050年配额将逐步减少。在这种情况下，有效管理已生产和已经存在的F气的战略对于确保其效果至关重要。对环境的缓解。到现在，从报废设备或翻新系统中释放出来的大多数F气被释放到大气中或被销毁。但是，为了提出一种经济有效的方法来适应F气的逐步淘汰，必须加大分离和再循环的力度。这项重要的审查旨在修订当前的F气管理问题和策略，并概述可用于在循环经济原则下为建立可持续市场做出贡献的创新策略。
