Abstract Details

2016, Master of Science, University of Toledo, Mechanical Engineering.
In recent history, the manufacturing of products and waste generation has significantly increased, causing an increase in the amount of waste residing in landfills. To promote sustainability, the recycling industry has embarked on two major goals: the reuse of expensive post-consumer materials and the reduction of the amount of waste in landfills. In recent years, the recycling of various materials such as aluminum, newspapers, and steel was proven to be very efficient and economically viable. However, recycling of plastics was a much more challenging task, mainly due to the inability to accurately and efficiently sort the different types of plastic out from other waste. The goal of this research was to introduce a new technique for sorting non-magnetic materials (including shredded plastics) by the use of ferrofluid and an imposed magnetic field. By submerging shredded post-consumer materials into a pool of ferrofluid and imposing a magnetic field gradient, the density of the fluid can be adjusted, and can cover a broad range of densities by changing the magnetic field strength. Using this phenomenon, a sink-float separation technique can be developed as future research. Experimental testing was conducted for validation by developing a ferrofluid separation model. Additionally, experimental testing was carried out to ensure the accuracy of the theoretical findings. With an accurate theoretical model, the tough to sort, low-density plastics were then analyzed for separation.
