项目摘要

The broader impact/commercial potential of this Partnerships for Innovation – Research Partnerships (PFI-RP) project is to develop a novel, environmentally friendly, profitable recycling process utilizing advanced chemistry and equipment design for the recovery of valuable and critical metals from waste printed circuit boards. Currently, the most common methods used to recycle waste electronics are through combustion in a smelting process or through low cost, off-shore labor. If successful, the project will enable a simple, efficient, and low-cost option for recyclers to develop vertically-integrated, domestic supply chains for the recovery of critical and valuable metals from electronic wastes. This process will be a direct replacement to the combustion of E-Wastes with significant reduction in environmental impact. Success will enhance the economic viability of the domestic recycling supply chain and further contribute to environmental justice by lowering exploitation of vulnerable communities. The proposed project aims to develop an integrated, low-cost, near closed loop system for the recovery of metals using liquid systems without the use of harsh acids or cyanide. To achieve this objective the multidisciplinary team seeks to 1) develop control methodologies for the integrated leaching of base metals with the use of a regenerated oxidizer, 2) design and validate a small zero-emission and scalable metal plating reactor for recovering copper, 3) develop electrolyte purification strategies to minimize waste streams, and 4) demonstrate gold leaching and recovery. The anticipated output will be an integrated flowsheet for the recycling of E-Wastes, economic value stream maps, and a technical/economic assessment of the viability of the technology. Successful completion of the project will enhance the circular economy and preserve scarce global resources.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 研究合作伙伴关系（PFI-RP）项目是利用先进的化学和设备设计来开发一种新颖，环保，有利可图的回收过程，以从废物印刷电路板上恢复有价值和关键的金属。当前，用于回收废物电子产品的最常见方法是通过在冶炼过程中或低成本，离岸劳动力的组合。如果成功，该项目将为回收商提供一种简单，高效且低成本的选择，以开发垂直集成的国内供应链，以从电子废物中恢复关键和有价值的金属。该过程将直接替代电子垃圾的混合物，并显着减少环境影响。成功将增强国内回收供应链的经济可行性，并通过降低对弱势社区的剥削来进一步促进环境正义。拟议的项目旨在开发一个综合，低成本的近封闭环系统，用于使用液体系统回收金属，而无需使用危险酸或氰化物。为了实现这一目标，多学科团队寻求1）使用使用重生的氧化剂来开发基础金属综合步行的控制方法，2）设计和验证一个小的零发射和可伸缩的金属电镀反应器来恢复铜，3）3）开发电解质净化策略，以最大程度地减少浪费流以及4）散步金色的步行和回收。预期的产出将是用于回收电子垃圾，经济价值流图以及对技术可行性的技术/经济评估的综合流。成功完成该项目将增强循环经济并保留稀缺的全球资源。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
