In aspects of waste disposal, construction and demolition processes tops the industries that generates the most waste. In attempts towards sustainability, these industries are also considered by experts as a great source of recyclable materials since items at their disposal are still deemed as useful and beneficial. In order to fully understand this scenario, you must first know which recyclable materials are fitted to be reused after demolition.
Concrete, Bricks & Blocks
Experts believe that concrete, bricks and blocks are among those materials with the least waste level. Statistics indicate that concrete’s waste level is at 4 percent while bricks and blocks are at 6 percent. These materials can be recycled by crushing them into a rubble. They are then repurposed, sorted, and screen unto which their contaminants are being removed. The finished recycled concrete, bricks or blocks can be used as an aggregate, fill, road base or riprap.
Gypsum is a waste material that is easy to recycle as compared to its counterpart. It involves the removal of contaminants like screws and nails, followed by separating the paper. It is either grinded into a powder-like consistency or moulded into pellets. Industries that purchase recycled gypsum used them for various applications.

Glass can be recycled in a variety of ways. It can either be crushed, screened, air classified, optical sorted, size classified, washed and dried. They can be utilised as decorative materials, fluxing agents, insulation and sports turf applications.
Metal recycling involves collection, sorting and shredding. Scrap metal recycling processes included melting and purifying the material and then cooling them to solidify. Metal variants like steel, copper and brass are often the most common to recycle. They can be modified to produce appliances, furnishing, fixtures and lighting.
Standard plasterboard are those that are disposed but remain uncontaminated by paint or any other chemical. They can be incorporated to an aerobic composting system. They are not harmful when added to soil, specifically clay.
