The transboundary movements of waste in Hong Kong are mainly caused by international trading of waste for recycling purposes. The majority of these recyclable non-hazardous wastes such as plastic waste, metal waste and scrap paper are destined for recycling in Hong Kong or the nearby areas. The substantial volume of waste import, export and re-export activities are driven mainly by the manufacturing and industrial activities in southern China and their demand for recovered scrap materials as raw materials.
The USA, Japan, and other regions in southern China are the major waste trade partners of Hong Kong. In general, waste is shipped from developed countries such as the USA, Japan, and the United Kingdom through Hong Kong into southern China.
