How Construction Companies Recycle Demolition Materials

By Construction Tech Review | Tuesday, January 26, 2021

The construction companies are reusing the Construction and Demolition (C&D) materials to reduce virgin materials' requirements. 

FREMONT, CA : Construction and Demolition (C&D) materials comprise the debris created by houses, roads, and bridges during construction, renovation, and demolition. EPA supports a Sustainable Materials Management (SMM) strategy that recognizes some C&D materials as resources that can be utilized in new construction projects, eliminating the need for virgin materials to be mined and processed.

What is C&D Materials?

Construction and demolition (C&D) materials are created by constructing new buildings and civil engineering structures and during the restoration or demolition of existing buildings and civil engineering structures (including deconstruction activities). Public works programs, like streets and roads, bridges, power facilities, piers, and dams, are part of civil engineering systems.

Advantages of Reducing the Disposal of C&D Material

Lowering the quantity of C&D products disposed of in landfills or incinerators can include:

• Establish jobs and economic activities in the recycling sector and provide better business prospects within the local community, particularly when deconstruction and selective demolition processes are used. The 2016 EPA Recycling Economic Information (REI) Study showed that 175,000 jobs were generated by recycling C&D materials in 2012.

• Minimizing construction project costs by avoided purchase or disposal expense and donation to eligible 501(c)(3) charities of recovered goods, which offers a tax advantage. Onsite recycling also decreases the cost of transportation.

• It leads to fewer waste facilities, potentially decreasing the environmental concerns involved.

• The environmental effect of the exploitation and use of virgin resources and the production of new materials is balanced.

• Conserve space for landfills.

Materials that can be Reused

The critical advantage of material reuse is resource and energy, which is prevented by decreasing new materials' production. Such C&D materials and applications widely reused include:

• Things such as doors, hardware, appliances, and fixtures are easy-to-removed. During the restoration or on other work, these can be reclaimed for donation or use.

• To prevent the necessity to cut full-length timber, wood cutoffs can be used for cripples, lintels, and blocking. On-site, scrap timber may be chipped and utilized as mulch or groundcover.

• De-papered and crushed gypsum can be utilized as a soil amendment in moderate amounts.

• On-site, brick, concrete, and masonry may be recycled as fill, sub-base material, or bedding for driveways.

• In interior walls, excess insulation from exterior walls may be used as material for noise deadening.

• Paint might be remixed and utilized for other jobs in the garage, storage areas, or as a primer coat.

• For recycling, packaging products may be returned to manufacturers.
