The construction process generates a significant amount of waste. Every new building contributes to the global volume of construction waste, which is often sent to landfills. Every year, 1.3 billion tons of waste is produced from various cities. Recycling prevents a vast amount of this waste from ending up in landfills, thus slowing down the depletion of natural resources. Recycling, which requires much less energy compared to the production of new materials, reduces the carbon footprint and reduces the high amount of water used in material production.

Construction waste is generated in various amounts during the demolition of a structure, transportation of materials, and use in construction. Construction waste that is not recycled accumulates and forms huge landfills. To prevent this, recycling in architecture offers two primary approaches:
- Using a recycled material as a building element
- Reusing construction waste in another construction
Selling saleable scrap and donating waste can reduce waste generation to a certain extent, while reusing construction waste in another project also reduces overall costs.
Construction waste materials:

Construction waste materials that can be frequently recycled can be listed as follows:
Concrete and Rubble: Concrete waste, one of the most used materials in construction, can be crushed and sized to be used as aggregate or filler in new concrete mixtures. In addition, recycled concrete can be used as a sub-base for walkways or highways.
Asphalt: Grinding old asphalt layers and using them in new asphalt mixtures supports recycling.
Wood: Crushed and fragmented wood can be used as fuel or as lumber components in areas such as cladding, flooring, and roofing. Recycling wood prevents deforestation caused by excessive consumption.
Metal Waste ( Iron, Steel, Aluminum): Melted and reshaped metals can be used for cladding modules, structural elements, roofing, and more. Metal recycling, which prevents excessive greenhouse gas emissions, benefits the natural ecosystem.
Bricks, Tiles, and Ceramics: Crushed and sized, these materials can be reused as fill material and aggregate. Recycling these materials, which make up a significant portion of construction waste, significantly reduces waste.
Glass: Glass, which is produced at high temperatures and causes a large amount of energy consumption, can be melted, reshaped, and reused.
Plastic: Plastic waste, which is very harmful to the environment and ecosystem, can be reused as a coating on facades, walls, roofs, etc.
Cardboard and Paper: Paper waste, which is frequently generated in construction, can be recycled into new paper products.
