There are different types of construction waste. The classification is done based on the type of material:

• Concrete and Bricks
• Tiles and Ceramics
• Wood, Glass and Plastics
• Insulation, Fiber glass and Asbestos
• Metallic Waste (such as electrical wires and cable)
• Soil and Dredging Spoil
• Cements, Paints and Varnishes
• Adhesives and Sealants
• Gypsum

Recycling concrete waste from a demolition involves several steps. The concrete waste is fed in to the crusher machine which breaks down in to smaller pieces. Special industrial equipments like excavator with hammers are used to breakup bigger pieces.  Further, the concrete is examined to remove any specific impurities and sorted in to large and small aggregate particles.

With higher focus on the environment hygiene and safety, it is extremely important for the construction industry to give primacy to the aspect of waste reduction. Here are some top ways to minimize construction waste.

• Procure the right amount of material – Ordering the right amount of materials from the right source at the right time for a project is an important aspect. Try to choose high quality materials that have low environmental impact.
• Use prefabricated building materials – Prefabricated building components can reduce construction waste. As these modular systems tend to have low exposure to the weather, they can be easily reused and residual materials can be stored on-site for future projects.
• Adopt deconstructing – Adopt deconstructing a structure, instead of demolishing. Deconstructing increase environment safety by reducing pollution.
• Recycle and reuse – Reusing and recycling involves using materials that are excess. For this process, try to use tools like waste segregation, waste audits and waste disposal plans.
• Proper storage of construction materials – Storing, covering and protecting construction materials like bricks, wood in an adequate manner can help prevent from accidental damage.

Construction and demolition sites often tend to generate different types of waste. Some of the common types of construction waste that can be reused include:

• Wood (for interior finishes, furniture, or compost)
• Concrete (for road construction and landscaping projects)
• Bricks and masonry (for pathways, retaining walls, or decorative elements)
• Scrap metal (for use in new construction or manufacturing processes)
• Plastic (for innovative building materials like insulation)
• Asphalt (for new asphalt mixtures)
• Gypsum (for new drywall or used as a soil amendment in agriculture)
• Glass (for new glass products or construction materials)
