Vietnam has a population of about 100 million people, and more than 60% are young and middle-aged laborers. The per capita salary is 300-400 US dollars/month. The labor cost is low. The average annual GDP growth rate is more than 7%, and the growth momentum is strong.


At present, there are two Vietnamese PVC and PET plastic manufacturers with an annual output of 300,000 tons. There is only one PP plastic manufacturer in Rongju Factory in Guangyi Province, with an annual output of 150,000 tons. Domestic plastic companies in Vietnam can only supply 20-30% of plastic raw materials by themselves, and about 70-80% (about 3 million tons) of plastic raw materials rely on imports.


Vietnam's demand for waste plastics ranks first among Southeast Asian countries. The market for recycled plastics in Vietnam includes PET, PP, PE, PS, ABS, and PA. Main import ports: Haiphong, Ho Chi Minh.


PET: Chemical fiber plants that use PET waste as raw materials. There are 13 chemical fiber plants throughout Vietnam, and the annual demand for PET waste is 300,000-400,000 tons. At present, the country can only meet 1/3 of the quantity, and 2/3 of about 200,000 to 300,000 tons need to be imported.


PET straps: There are about 40 factories in Vietnam. 20% are sold locally in Vietnam and 80% are exported to China.


LDPE: Imported LDPE industrial film and LDPE recycled particles are used to produce packaging bags for daily shopping bags.


HDPE: In addition to blow molding and piping, a sunshade net factory with tens of thousands of tons of bottle caps as a raw material is ready to be put into production in the near future.


PP waste: processed to make woven bags and PP rope.


PS, ABS waste: the production of bags, small home appliances, tableware and other markets is also steadily increasing.
