Palladium (Pd) is a widely used catalyst in the modern chemical and pharmaceutical industries and is in short supply due to increasing global demand and supply chain pressures. Our recent studies have shown that the bacterium Desulfovibrio alaskensis can be used to recover Pd from waste for reuse as nanoparticle catalysts which work under energy-efficient manufacturing conditions. The Pd catalysts derived from the bacteria display enhanced chemical properties and can catalyze the formation of small molecules of use in the pharmaceutical industry. Here, we will (i) optimise the nanoparticles for this catalysis (ii) devise routes for their reuse and remanufacture so that the Pd can be continuously recovered and reused and (iii) expand the portfolio of reactions catalysed by the bacterially derived Pd and demonstrate catalysis with other metal nanoparticles. This emerging biotechnology paves the way for the sustainable use of Pd, creating new circular pathways to improved Pd catalysts and replacing the current linear model of Pd catalyst use, which creates waste, is unsustainable and reliant on insecure supply chains.

钯 (Pd) 是现代化学和制药行业广泛使用的催化剂，由于全球需求和供应链压力不断增加，钯金供应短缺。我们最近的研究表明，阿拉斯肯脱硫弧菌（Desulfovibrio alaskensis）细菌可用于从废物中回收钯，并重新用作纳米颗粒催化剂，在节能制造条件下工作。从细菌中提取的钯催化剂具有增强的化学性质，可以催化制药工业中使用的小分子的形成。在这里，我们将（i）优化用于这种催化作用的纳米颗粒（ii）设计其再利用和再制造路线，以便钯可以不断回收和再利用，以及（iii）扩大由细菌衍生的钯催化的反应组合并证明与其他金属纳米颗粒的催化作用。这种新兴的生物技术为钯的可持续利用铺平了道路，创造了新的循环途径来改进钯催化剂，并取代了目前钯催化剂使用的线性模型，这种模型会产生废物，是不可持续的，并且依赖于不安全的供应链。
