Resource utilization of construction waste: How to turn rubble into treasure

Construction waste is a large and abundant type of waste, but if handled properly, it can be transformed into valuable resources. This not only saves natural resources and reduces environmental pollution, but also achieves a win-win situation for both economic and environmental benefits. Crushing and recycling, and the remanufacturing of building materials, are common methods for the resource utilization of construction waste.

Crushing and recycling involves crushing hard construction waste such as concrete and bricks using crushers, for use in areas such as road base and foundation filling.

This construction waste, generated from the demolition of old buildings, is processed and transformed into fine aggregates, which are then processed into recycled bricks and other building materials for use in new construction. They are often used for filling foundations, building non-load-bearing walls, or as part of the road base under asphalt roads. Recycled aggregates can also be used in newly built parks, creating continuous small hills through landscaping.

Building material remanufacturing refers to the reprocessing of reusable parts of construction waste, such as producing recycled concrete and recycled bricks from crushed concrete and bricks.

The resource utilization of construction waste is the direction of construction waste management, but we need to overcome various challenges and continuously promote technological innovation and policy support to achieve the goal of turning waste into valuable resources.
