Hai Phong should improve solid waste management in two ways: minimise damage to the local environment and public health, while making the most of the potential for growth. Major industrial waste includes: i) vamish products (paint, varnish, enamel glass), adhesives, sealants and printing inks; ii) waste oil, waste from liquid fuel, organic solvent waste, refrigerants and propellants; and iii) packing waste, sorbent, rags, filter materials, protective fabrics. In Hai Phong’s industrial zones, such as Nomura, Dinh Vu, Trang Due, south of Kien Bridge and Do Sonthese, industrial waste is collected and treated (mostly by burning, while gas and oils are recycled) by five private companies.
