Crushing and grinding machine for construction waste recycling

Construction waste management

Esponsibly managing waste on a construction jobsite is a vital component of sustainable building. In this context, managing waste means minimizing the construction waste or demolition debris (C&D) that leaves the jobsite for landfill disposal.

C&D waste disposal triggers a sequence of adverse effects that are not always apparent to building professionals. These include the loss of useful property, wasted materials and embodied energy, greenhouse gas generation, and environmental stressors associated with producing new materials instead of using existing materials. The number of C&D landfills is declining, which means fewer disposal options, greater hauling distances, and increased fuel consumption and vehicle emissions. Capping, closing, and monitoring landfills, and cleaning up leaking or contaminated landfill sites drain public funds.

Construction Waste:

Waste materials generated by construction activities, such as scrap, damaged or spoiled materials, temporary and expendable construction materials, and aids that are not included in the finished project, packaging materials, and waste generated by the workforce.

Demolition Debris:

Waste resulting from removing a building from the site by wrecking.

Land Clearing Debris:

Vegetative waste materials removed from a site.

Disposal (or Landfilling, or Landfill Disposal):

Depositing materials in a solid waste disposal facility licensed for the subject materials (in this case, C&D materials).

Recycling:

Introducing a material into some process for remanufacture into a new product, which may be the same or similar product or a completely different type of product.

Salvage:

Recovery of components, products, or materials for the purpose of reusing them for the same or similar purposes as their original use. Reuse: The subsequent use of a material, product, or component upon salvage.

Deconstruction:

The systematic disassembly of a building, generally in the reverse order of construction, in an economical and safe fashion, for the purposes of preserving materials for their reuse.

Source Separation (or Segregation):

Keeping materials separated by type from the time they become scrap or waste until the time they are salvaged or recycled.

Off-Site Separation:

Sorting and separating commingled waste at a location other than the construction jobsite, that location having been established for the purpose of recycling.

Commingled:

Materials of varied types deposited into the same receptacle or pile, or mixed together during demolition.

C&D waste materials

The vast majority of construction waste and demolition debris materials can be reused on site, salvaged for reuse on-site or elsewhere, or recycled. Diverting 90% of construction jobsite waste and over 80% of demolition debris from landfill disposal is not uncommon. These materials include:Landscape and land clearing debris (green wood materials), Asphalt pavement, Gravel and aggregate products, Concrete, Masonry scrap and rubble (brick, concrete masonry, stone), Metals (ferrous and nonferrous), Clean wood (dimensional lumber, sheet goods, millwork, scrap, pallets), Plastics (films, containers, PVC products, polyethylene products), Asphalt / bituminous roofing, Insulation materials, Glass (un-tempered), Door and window assemblies, Carpet and carpet pad, Fibrous acoustic materials, Ceiling tiles, Plumbing fixtures and equipment, Mechanical equipment, Lighting fixtures and electrical components, Cardboard packing and packaging, Others.
