    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Regan George; [2023]
    Keywords : PHA; HTC-substrate; Polymer;

    Abstract : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.
