[1D10] Catalytic Upcycling of Plastic Wastes into High Value-added Chemicals

キーワード:Plastic waste, Catalytic upcycling, Hydrogenolysis/hydrocracking

Plastic is one of the most commonly used materials worldwide because of its versatile applicability, low cost, durability, and lightweight properties. According to the Organization for Economic Co-operation and Development (OECD) report released in 2022, only 9% of plastic waste is successfully recycled globally, and the majority of this waste is either incinerated (19%), landfilled (50%), or lost to the environment (22%). Globally, post-consumer plastics are predominantly recycled via mechanical recycling, in which the material is washed, cut, melted, and transformed into raw materials. However, mechanical recycling is typically accompanied by the degradation of plastic properties (downcycling). This talk will discuss an alternative way to recycle plastic waste into higher-value materials (upcycling) using catalysts.
