Improving Recycling Efficiency of Portable Electronics by Automating Battery Disassembly

Improving Recycling Efficiency of Portable Electronics by Automating Battery Disassembly

This project proposes to develop an automated and integrated battery disassembly process for EOL PCEs using a modular approach, as well as design and develop a component disassembly and battery removal process using a combination of mechanical (e.g., robotic disassembly, water-jet cutting), chemical, and thermal approaches to increase EOL PCE materials recover and processes throughputs

Upon completion, this project will design a prototype system, built and operated to confirm system effectiveness. This project will increase secondary materials by 0.03 million metric tons (MMT) of e-waste, 3.6 PJ energy reduction, 0.180MMTCO2e. Assumptions based on recovery of 20% of 150,000 metric tons per year of PCE discarded.

Design for RE-Solar

Design for RE-Solar

This traditional research and development REMADE proposal is to create a framework that addresses the knowledge gaps of RE-SOLAR design. The proposed framework will offer impact projections for future PV panel waste streams (globally and for the US) based on predictions of global PV growth, provide LCA of various PV designs, and demonstrate new concepts and innovation for the design of an industrial scale PV recycling plant. The proposal is a continuation of Project 18-01-DE-07.

Upon completion, this project will deliver PV in a circular economy (PV ICE) version 1.0.0 software tool with the capability to analyze embodied energy and equivalent carbon dioxide emissions given changes in Si PV technologies, new PV technologies such as tandem cells and perovskites, and effects of changing raw material sourcing or increasing recycled material in manufacturing; The tool will also be used to analyze reduced material consumption and the effect of open-loop versus closed-loop recycling on future CO2 emissions, energy, waste streams, and material economic value. This project will reduce primary feedstock by 1.08 million metric tons (MMT), 26.6 PJ energy reduction, 1.34 MMCO2e. Assumptions based on preliminary results of the exploratory project.

Chemical Recycling of Mixed Plastics and Valuable Metals in the Electronic Waste Using Solvent-Based Processing

Chemical Recycling of Mixed Plastics and Valuable Metals in the Electronic Waste Using Solvent-Based Processing

This project seeks to demonstrate the potential of solvent-based extraction process to recover plastics mixed metals and plastics electronic waste (e‐waste) for cross-industry reuse. Following extraction of the plastics, the mixed-stream would be primarily metals. The plastics would be recovered from the process solvent using an anti-solvent. If successful, this project will significantly increase the recycling rates of e-waste, and the recovery of plastics and metals from this source material. The potential energy savings and emission reduction from this project are estimated at 16PJ per year and 334,000 MT of CO2eq. per year.

Low-Cost, High-Value Metal Recovery from Electronic Waste to Increase Recycling and Reduce Environmental Impact

Low-Cost, High-Value Metal Recovery from Electronic Waste to Increase Recycling and Reduce Environmental Impact

This project seeks to adapt relatively low-cost and low-energy leaching technologies to directly recover copper and precious metals from e-waste.  This approach will enable the recovery of these metals from the mixed metals and plastics streams from e-waste and also enable recovery of the plastics. This technology could replace energy-intensive pyrometallurgical processes such as high-temperature smelting that might otherwise be used to recover metals, but due to the high-temperature the plastics are consumed. 

Utilizing these less energy-intensive and lower-cost technologies will provide the economic incentive to dramatically increase e-waste recycling by as much as 20%. The potential energy and emissions reduction are estimated at 21PJ per year and 1.2 million MT of CO2eq per year.

Evaluation of Logistics Systems for the Collection, Preprocessing and Production of Secondary Feedstocks from E-waste

Evaluation of Logistics Systems for the Collection, Preprocessing and Production of Secondary Feedstocks from E-waste

The objective of this project is to develop an e-waste logistics model that integrates transportation, manufacturing processes, and markets to enable optimal recovery and recycling of e-waste. The model will enable identification of least cost options for increasing e-waste collection and recycling.
