Research on Plastic Recycling from a Global Perspective and PET Recycling Schemes in Hong Kong

This paper first introduces the global production volume and types of plastics, their impacts on the environment, and the current treatment status. Then it elaborates on the plastic recycling situations in Hong Kong, Taiwan, and Bernburg, Germany respectively. In Hong Kong, the plastic recycling rate is low, and landfill is the main treatment method, facing problems such as high transportation costs and low plastic density. Taiwan performs outstandingly in resource recycling with a high garbage recycling rate. Bernburg, Germany processes plastic waste through strict classification, incineration, and recycling factories. The article also details specific measures for the recycling object PET, including methods such as mechanical recycling, incineration, and landfill, as well as their advantages and disadvantages. Finally, it proposes feasible schemes for managing plastic waste in Hong Kong, such as garbage classification, mobilizing residents to recycle, building recycling stations, and internal digestion. It also analyzes the mechanical recycling technology for handling PET bottles in Hong Kong and the economic and environmental benefits of this project.
