Construction and demolition waste recycling is the process of converting waste materials derived from construction, renovation, and demolition activities into reusable products. The Construction and demolition waste recycling is also known as CDR.
Construction and demolition waste recycling is the process of converting waste materials derived from construction, renovation, and demolition activities into reusable products. also known as CDR. There are many different types of CDR processes available for construction and demolition waste recycling. Some are more common than others depending on the type of material that has been generated during a project.
CDR uses many different types of technologies to convert construction materials into usable products such as asphalt paving materials, concrete aggregates and bricks, crushed stone or gravels for roads/driveways/parking lots/etc., insulation foam board insulation panels (or “blanks”) used in new home construction, etc.. The amount of recovered asphalt pavement depends on the amount of asphalt pavement removed during excavation activities (e.g., road widening projects), which varies regionally depending on local laws and regulations governing road reconstruction activities.
What Are C&D Materials?
Construction and demolition materials are the waste leftover from building, remodeling and demolishing structures. These materials are often referred to as C&D or C/D material. The term “construction and demolition” is derived from the fact that most of these materials come from demolished buildings or structures, but some may come from construction sites.
The purpose of recycling C&D material is to reduce the amount of waste going into landfills and to increase the use of recycled materials in manufacturing new products. By recycling C&D material, you can also help save money on disposal costs by reducing the amount of waste sent to landfills.
What Can be Recycled?
The first step in recycling construction and demolition materials is determining what can be recycled. How it should be recycled. There are many different types of C&D materials, ranging from concrete to copper wiring, so it’s important to know how each should be handled when it’s time for disposal. The following items should always be recycled:
- Concrete blocks
- Reinforced concrete (concrete with wire mesh inside)
- Bricks
- Glass
- Plastics
- Salvaged building components (doors, windows, and plumbing fixtures)
- Trees, stumps, earth, and rock from clearing sites
- Metal pipes
Benefits of Reducing the Disposal of C&D Materials
- Reduction of waste disposal costs
- Reduction of construction costs
- Improved site aesthetics
- Improved air quality and health of nearby residents
- Reduced impacts during construction and restoration of natural habitats and ecosystems.
Reduce, Reuse, Recycle and Rebuy C&D Materials
- Reduce: Reduce the amount of C&D materials you generate by reducing overall site size, the number of materials and the amount of waste generated. This can be achieved through deconstruction; in fact, deconstruction is a great way to reduce your waste stream.
- Recycle: Some C&D materials can be recycled; others cannot be recycled or reused. You should try to recycle all of your materials that can be recycled. If you cannot recycle your materials, then consider donating them for reuse instead of sending them to landfill or incineration.
- Rebuy: If you are unable to reuse or recycle your C&D material, then consider purchasing new materials instead of buying reused ones.
