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.

Recovery of Plastics and Natural Fibers from Non-Recyclable Municipal Solid Waste for Composites Production

Recovery of Plastics and Natural Fibers from Non-Recyclable Municipal Solid Waste for Composites Production

This project aims to recover secondary feedstocks of plastics and fibers from mixed flexible plastics (MFP) stream of nonrecyclable waste and develop advanced compounding and manufacturing processes to convert these recyclates to fiber-reinforced polymer composites.

Upon completion, this project will develop an integrated fractionation method that combines novel wet separation and fractionation approaches with air classification and NIR-based separation to decontaminate and obtain four plastic fractions and one natural fiber fraction from waste streams, processable material formulations out of these recyclates, and an advanced compounding procedure based on Ring Extrusion technology that produces high quality feedstocks. This project will reduce primary feedstock by 1.12 million metric tons (MMT) of flexible plastics, 96.7 PJ energy reduction, 1.52MMCO2e. Assumptions based on utilization of 20% of 5.62MMT of flex plastics available for recovery.

Demineralization of Carbon Black Derived from End-of-Life Tires

Demineralization of Carbon Black Derived from End-of-Life Tires

Alternative process technologies will be experimentally evaluated to upgrade carbon black recovered from end-of-life tires to meet carbon black market quality specifications. Approximately 3.87 Mt of waste tires accrue every year in the United States. If all these tires were processed to recover the carbon black, about 1.1 Mt of carbon black could be recovered to use as a secondary feedstock.

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.

Determining Material, Environmental and Economic Efficiency of Sorting and Recycling Mixed Flexible Packaging and Plastic Wrap

Determining Material, Environmental and Economic Efficiency of Sorting and Recycling Mixed Flexible Packaging and Plastic Wrap

This project will further develop technology to recover flexible plastic film from a material recovery facility (MRF). Market opportunities for the recovered film will be examined and the resulting economic and environmental impacts will be evaluated. The technology to be developed in the project, if implemented broadly, has the potential of capturing almost 11 billion pounds of flexible plastic packaging and plastic wrap that is currently landfilled each year.

Biological & Bio-Mechanical Technologies for Recycled Fibers to Regain Fiber Quality and Increase Secondary Feedstock in High Value-Added Paper Grades

Biological & Bio-Mechanical Technologies for Recycled Fibers to Regain Fiber Quality and Increase Secondary Feedstock in High Value-Added Paper Grades

The goal of this project is to develop new technologies for removing contaminants from recycled paper to less than 0.5% and to develop technologies for regaining or fiber quality without using only mechanical refining. The new technologies developed will help paper recycling industry to produce much cleaner pulp and higher quality fibers so more recycled fibers can be used in place of virgin fibers in high grade paper. The new technologies developed based on new enzyme applications will also reduce the energy consumptions in both contamination removal and fiber refining process and increase the yield of the fiber recycling.

Systems Analysis for PET and Olefin Polymers in a Global Circular Economy

Systems Analysis for PET and Olefin Polymers in a Global Circular Economy

This exploratory project will develop a framework for systems analysis of PET and polyolefins in the context of a circular economy. These polymeric materials are currently recycled at low rates in the U.S., but are among the largest volumes of polymeric materials that are recyclable. The objective of this project is to develop a framework that will enable analyses of factors such as new recovery technologies that might enhance the recovery and recycle of polymers including polyolefins and PET.
