“Transport Batteryfication” Analysis Of Pre-Recycling Phases Of End-Of-Life Electric Vehicle Lithium-Ion Batteries From An Irish Perspective, Matt Mcguinness

Masters

Transport plays a key role in maintaining the economic prosperity of our society. However, transport has remained reliant on fossil fuels, a main contributor to climate change. New EU and Government policies aim to decarbonise the transport sector through batteryfication by shifting to electric vehicles. The lithium-ion battery will underpin this strategy.

Lithium-ion batteries have a limited lifespan for automotive applications, this will bring new and unprecedented challenges for end-of-life waste management. The recent growth of electric vehicles is expected to continue exponentially which raises important questions on how to process this new waste stream.

This study investigates the recycling …

Development Of A Separation Solution For Braided Polyester/Polyolefin Ropes And Lines, Stefan Fricke, Robbie Huton

WWU Honors College Senior Projects

The following report summarizes the research performed for the project sponsored by Net Your Problem. The research focuses on using depolymerization reactions as a method of separating polyester from polyolefin material in braided lines commonly used in the fishing and crabbing industries. Currently the mixed fibers in these lines are too comingled to be separated by conventional mechanical recycling methods. The glycolysis reactions were chosen to take advantage of the very different solubilities of polyester and polyolefins. Ethelene glycol breaks down the PET into oligomers and BHET monomer while leaving the polyolefins unreacted. The products of the reaction can then …
