Hanoi is currently clearing land for 1,428 projects, including four new bridges spanning the Red River (Hong Ha, Me So, Van Phuc, and Ngoc Hoi), ring roads, and the widening of National Highways 1 and 6.
This is generating more than 10,000 tons of construction waste daily, including concrete, bricks, stone, mortar, metal, wood, plastic, glass, excavated soil, and sludge.
This is four to five times the normal volume of waste.
Unlike household waste, construction debris is a secondary resource because most of it retains value with proper sorting and processing.
Once crushed, screened, and treated, the waste can be transformed into aggregate for roads, land reclamation materials, non-fired bricks, concrete, and components used in manufacturing construction materials.
