Go Build Something

How do you reuse leftover scrap materials on the site?

Consider reusing materials on site to reduce your disposal efforts and costs. Some options to consider:

  • Joist off-cuts - cut up and used as stakes for forming or for headers around openings in the floor assembly
  • Leftover rigid insulation - used as ventilation baffles in attics or installed into house envelopes as joist header assemblies
  • Pallets - return to the vendors
  • Salvageable materials - can be given to an organization that will collect used construction materials and resell them

 

Potential Uses for Materials Commonly Found in C&D Debris

 

Material Potential Use
asphalt road sub-base fill
concrete

Crushed and mixed to make new asphalt cement blocks;

crushed and screened aggregate can be used in asphaltic concrete

dirt Landscaping landfill cover
metal Scrap metal dealers
wood Timber/wood pulp: shredded for fuel, animal bedding, landscaping, manufactured building products, and compost
brick Masonry crushed for ornamental stone
glass Fiberglass insulation, sand blast, aggregate in asphalt reflective beads
gypsum Soil amendment, gypsum board, absorbent media
plastic

 ABS: plastic lumber

PVC: highway barriers

Polyethylene: traffic cones

polystyrene Insulation
porcelain Crushed for aggregate
corrugated cardboard Paper mills, fuel pellets
carpet Landfill cover
roofing shingles Asphalt paving

 

Aggregate recycling rates are greatest in urban areas where replacement of infrastructure is occurring, natural aggregate resources are limited, disposal costs are high or strict environmental regulations prevent disposal.

Factors affecting aggregate recycling:

  • Product size
  • Operational design
  • Labor
  • Feed source material characteristics
  • Energy
  • Infrastructure life
  • Recycled product specifications
