4D-BIM to enhance construction waste reuse and recycle

Hardened leftover amounts of concrete waste can be reused on-site as clean fill (DEP, 2019, Tam and Tam, 2006), a practice that is common to backfill and level up open areas to necessary grades . Besides on-site waste reuse, concrete is a material with high potential for off-site recycling.

The Importance of Concrete Recycling

Dec 29, 2017 · Construction and demolition (C&D) waste is a central component of the solid waste stream, amounting to roughly 25 percent of total solid waste nationally. The largest part of C&D material is concrete, which encompasses around 70 percent of C&D generated material before recycling, according to the U.S. EPA.

The most commonly seen and recyclable plastics are #1 (PET: clear plastics, like water and soda bottles), #2 (HDPE: usually more opaque plastics, like laundry soap and milk jugs), and #5 (yogurt, butter, sour cream

Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete. Small pieces are used as gravel for new construction projects.
