Deep eutectic solvents, especially the bio-based ones being used within this work, are 'green solvents' with low toxicity and sustainable sources. They can be used in a wide variety of processes ranging from the valorisation of food waste, to drug delivery systems. In this work we will be using deep eutectic solvents that have been used to semi-selectively recover metals from green technologies, such as electric vehicle batteries. We will examine the potential for these deep eutectic solvents laden with dissolved metals to be used as a feed for bacteria that produce metal nanoparticles and optimise the process accordingly by engineering the bacteria. Our aim is to be able to recover the metals, especially those that are categorised as 'critical materials', from green technologies that have come to their end of life, so that the metals can be used again, and to do so in process that is sustainable, low energy and environmentally safe.

低共熔溶剂，尤其是本研究中使用的生物基溶剂，是低毒性且来源可持续的“绿色溶剂”。它们可用于多种过程，从食物垃圾的增值到药物输送系统。在这项工作中，我们将使用低共熔溶剂，这些溶剂已用于从电动汽车电池等绿色技术中半选择性地回收金属。我们将研究这些富含溶解金属的低共熔溶剂作为产生金属纳米颗粒的细菌的饲料的潜力，并通过对细菌进行改造来相应地优化工艺。我们的目标是能够从已达到使用寿命终点的绿色技术中回收金属，特别是那些被归类为“关键材料”的金属，以便可以再次使用这些金属，并在过程中这样做可持续、低能耗且环境安全。
