Depending on the type of waste created, construction waste may be divided into the four primary types listed below.
Reusable materials
The solid wastes are re-used based on a number of factors, including quality, size, and pollution level. Stones, timber, ceiling panels, glass, and other materials may all be reused. These materials can also be sold outside to generate cash. The main benefit of this strategy is that it allows us to economize resources.
Recyclable materials
The majority of trash is recoverable, and new valuable goods may be generated from it. Cement, steel, glass, woods, paper, and other recyclable materials are only a few examples. The fact that these fine aggregates products use more water than typical fine aggregates is a key drawback. Melting metals (including steel bars), plastic (PVC), and glass may all be recycled. The majority of the waste management system's concepts are based on recycling. Even road building can benefit from recycled aggregates.
Unwanted waste
Every construction activity accumulates a certain quantity of unusable garbage. Unwanted garbage is sometimes labelled as demolition debris. These waste materials are frequently used to fill up holes in the ground.
Hazardous waste
Hazardous waste includes contaminated water and sewage, fluorescent bulbs, hydrocarbons, chemicals, components, silica materials, PFAS, and other items that cannot be disposed of properly. Environmental rules and regulations should be followed while disposing of certain forms of garbage.
The following are some of the most common waste products generated during building and deconstruction.
• Cement concrete
• Bricks
• Steel rebars and metals
• Aggregates
• Composites and formwork components
• Cardboard, Gypsum board, and other ceramic materials
• Wood
• Asphalt cement materials
• Textile materials, asbestos, glass, electrical and wire, and other materials
Below shows a document site waste and demolition protocol, although this is EU regulations the document is still useful to use as a guidance for dealing with site waste.
