FREMONT, CA: On a building site, waste production is unavoidable; even a tiny area can generate massive amounts of rubbish. According to the survey, construction and demolition debris generated 600 million tonnes in 2018.
Let’s see some different types of construction waste:
Bricks can also be reused in other projects if they haven't lost their structural integrity after being demolished. However, pollutants such as mortar and plaster may be included in brick debris, lowering the value of the bricks for reuse.
In that circumstance, businesses may seek to recycle their bricks. The process of brick recycling entails crushing the bricks into small bits for reuse as infill materials.
Ceramic and Tile are frequently available in building and demolition trash. It's possible that these materials are demolition trash or that the site has additional materials on hand once the job is over.
Ceramic and Tile may have some value for reuse in new projects if they are in good shape. However, if a corporation cannot use these resources, it may be able to sell them or send them to be recycled.
Old windows get frequently produced as a result of construction and demolition. That glass can be repurposed or recycled and melted down to make new goods. It can also be crushed and recycled for use in fiberglass or used as aggregate in concrete.
In demolition efforts, ferrous metal – iron and its alloys, such as steel — is frequently found in old pipelines. It has a high reusability and recycling value. It can be recycled almost entirely, resulting in very little waste with these components when adequately recycled. Ferrous metal also has the advantage of being repeatedly recyclable, allowing it to last for a long time in various construction projects.
Metals other than iron, known as nonferrous metals, have a high value for reuse and recycling. For example, pipes and components like nails and rebar commonly contain ferrous metals such as aluminum, copper, lead, and zinc. Copper and aluminum, which are desirable recyclable metals, are also found in electrical wires.
Stone and clay debris sometimes gets generated during construction and demolition projects. Stone in good condition may be a good option for reuse in the future. On the other hand, crushing procedures will pulverize the stone and clay into fine particles for aggregate filler. The gravel produced could be used in specialty products such as thermal insulating concrete or infill beneath roadbeds.
