Reference number : GC-2017-Q3-00615, amendment number : , agreement type : G, recipient legal name : Azimi, Gisele (University of Toronto), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : This proposal describes the plan for the development of a breakthrough technology based on supercritical fluid extraction (SCFE)_x000D_
for the removal of contaminants that cause color and odor in specialty chemicals such as waxes derived from recycled polymers._x000D_
Polyethylene and polypropylene feedstock contain various additives, such as fillers and colorants, which either degrade or carry_x000D_
through the depolymerization process; thereby causing intense dark colors and a pungent petroleum odor. The combination of_x000D_
color and odor imposes several challenges, limiting the potential markets of the waxes products. This project aims to develop an_x000D_
innovative, cost effective, and environmentally friendly SCFE process to purify the waxes by removing the contaminants. The_x000D_
purified waxes could then be utilized in a variety of market segments, including color masterbatch, roofing shingles, rubber,_x000D_
coatings, and road asphalt modifiers. Compared with traditional purification technologies based on solvent extraction and_x000D_
absorbent filters, SCFE process offers exceptional advantages, including fast reaction rates, little liquid waste, ease of separation_x000D_
of solutes, and fewer separation stages. It has been shown that supercritical CO2 dissolves various types polymers. It is therefore_x000D_
expected that the contaminants in polymers can be removed by SCFE. This project is highly beneficial for Canada and Ontario in_x000D_
terms of academic excellence and industrial competitive advantage, as it creates an opportunity to produce high-value water white_x000D_
waxes from reclaimed polymeric feedstock with a focus on clean technologies and enhanced resource efficiency. Also, top high_x000D_
quality personnel will be trained for careers in the Canadian and Ontario-based Chemicals sector., program purpose french : This proposal describes the plan for the development of a breakthrough technology based on supercritical fluid extraction (SCFE)_x000D_
