E-commerce based closed-loop supply chain for plastic recycling
The world is facing a grave plastic waste problem. It is not new that we hear about oceanic death and morbid landfills. Only 8% of all the plastic produced is recycled in the US. This grotesque situation has been worsened by the Chinese ban of plastic waste imports from the developed western …

A Local Solution to Plastic Pollution
Plastic pollution is a well-known issue across the globe with staggering facts such as: “Only 9% of all plastic produced has been recycled,” and “The Great Pacific Garbage Patch is a floating island of plastic waste spanning an area that is over twice the size of the state of Texas.” Locally, this …

Unwanted Project: Speculative Design for Circularity
More than 360 million tons of plastic are produced each year (2020, global plastic report), and only 9% can be recycled properly. With increasing climate change and the inevitable single-use waste stream produced in our everyday life, plastic pollution is rapidly outpacing the current effort to …

Incorporating Recycled Plastics in Asphalt Binders and Mixtures
Plastic has become an unavoidable material in modern life, and its existence spans from food packaging to transporting goods. Due to the low cost and durability of plastic products, the growth in plastic production has been increasing exponentially. The increased production increased plastic waste. …

Modification and Upcycling of Polyetherimide, Polystyrene, Polyethylene, and Polypropylene
Enhancing and recycling plastic are two important focuses in plastics research. In this dissertation, enhancing the property of polyetherimide (PEI) is first discussed, and two methods are introduced. Later, a new recycling strategy, the degradation-upcycling (Deg-Up) strategy, is presented. The …

Material flow analysis of plastic in Iceland : moving towards a circular economy
This research thesis analyzes the flow of plastic materials in Iceland and highlights changes needed to move the current system towards a more circular economy. A circular economy is an economic system that seeks to use materials to their fullest without needing to send them to a landfill and helps …

Hydrothermal Liquefaction of Plastic as an Alternative Recycling Method
As plastic pollution continues to escalate globally, the need for innovative recycling technologies becomes increasingly urgent. HTL is a thermochemical process that decomposes plastics feedstocks using water as a medium under near-critical conditions to produce valuable liquid products. This work …

CHARACTERIZATION OF A CARDBOARD RECYCLING FACILITY'S PLASTIC WASTE FOR BENEFICIAL USE
An issue with old cardboard container (OCC) recycling is the generation of a plastic waste that currently either gets land-filled or burned. A Wandel screen, a common process unit, generates 35% of overall rejects that contain 75% of the facility's total plastic output. Plastic-rich Wandel wastes …

Direct Force Measurement between Surfaces Coated with Hydrophobic Polymers in Aqueous Solutions and the Separation of Mixed Plastics by Flotation
… in flotation. If one wishes to separate plastics from each other by flotation, however, it would be necessary to render a selected plastic hydrophilic and leave the others hydrophobic. In the present work, the possibility of separating common plastics from each other by flotation has been …
