Abstract
This experimental thesis explored the technical feasibility of a temperature-controlled dissolution-precipitation process for recycling polyolefin household wastes. An extensive literature review defines the experiment's feed composition and experimental setup. Additionally, it inspects the potential for the process to become a sustainable addition to the existing plastic recycling system along with a basic analysis of the major costs of a commercial plant.
The study involved 5 experiments with the characterization of its outputs. The results demonstrate that the technique can handle common organic contaminates and non-target polymers in the feed without compromising the quality of the polymer product. The polymer products present characteristics that are comparable to the feed, which mostly consist of food-grade packaging. Suggesting the potential application of polymer products in the food and beverage industry, closing the loop for plastic use.
