Plastic waste is a significant environmental issue, with traditional waste management methods like incineration causing pollution and greenhouse gas emissions. Chemical recycling through innovative methods like pyrolysis offers a sustainable solution. This article explores the use of microwave (MW) heating technology for efficient conversion of polyolefins into ethylene and propylene, crucial for chemical recycling. By utilizing MW-absorbing heating elements (MWAHEs) like activated carbon (AC), the process can achieve high temperatures rapidly, enabling the direct gasification of polyolefins. The MW-assisted pyrolysis method not only reduces energy consumption but also improves the yield of valuable products like ethylene and propylene, essential for basic chemical production. The scalability and tolerability of this approach make it a promising candidate for large-scale plastic waste recycling processes. Efforts are focused on optimizing pyrolysis temperatures, reducing extra processing steps, and enhancing the overall efficiency of chemical recycling. With a positive sentiment towards this innovative approach, the article discusses the potential for revolutionizing plastic waste management and contributing to a more sustainable future.
