特殊金属和贵金属在现代社会中发挥着关键作用，因为它们对清洁技术和其他高科技设备具有特殊的重要性。这些“技术金属”的使用在过去30年里显著加速，它们在未来的充足供应对于在技术的帮助下建立一个更可持续的社会至关重要。回收利用可以大大有助于确保获得这些金属，保护金属资源，并减轻潜在的临时短缺。如果采用最先进的工艺进行技术金属的回收- -大多数只在低矿石浓度中进行- -与采矿相比，在能源、土地和水的需求方面也有相当大的好处。
Special and precious metals play a key role in modern societies as they are of specific importance for clean technologies and other high-tech equipment. The use of these “technology metals” has accelerated significantly over the past 30 years, and their sufficient future availability is crucial for building a more sustainable society with the help of technology. Recycling can contribute significantly to secure access to these metals, conserve metal resources, and mitigate potential temporary scarcities. If conducted in state-of-the-art processes, recycling of technology metals – which mostly occur in low ore concentrations only – offers as well considerable benefits compared to mining, with respect to energy, land, and water requirements.
