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. Construction (21.7 million tons) and demolition (353.6 million tons) activities

The important take-away is that not all plastics are recyclable materials.The symbols on the bottom of plastic containers tell us what type of plastic resin makes up the container. 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.
