Did you know that the United States is estimated to produce over 600 million tons of Construction and Demolition (C&D) waste each year? That’s more than twice as much as the municipal solid waste!

Globally, C&D waste is estimated to account for 30-40% of total waste generation, making it one of the largest waste streams in the world.

Understanding and managing C&D waste effectively is crucial for environmental sustainability.

What is C&D Waste?

Construction and Demolition waste is generated during the construction, renovation, and demolition of buildings and infrastructure. Surprisingly, it’s reported that roughly only 10% of C&D waste is generated during new construction, while the other 90% comes from demolition projects.

C&D materials often consist of the following:

• Concrete
• Wood
• Metals
• Bricks
• Drywall / Gypsum
• Plastics
• Glass
• Asphalt
• Plasterboard
• Vegetation
• Rock and Soil

C&D waste is composed of a variety of materials, some of which break down over time, while others remain stable and unchanged. For example, materials like wood and plastics can decompose or react chemically. Whereas materials such as concrete and asphalt remain largely unchanged for decades.

How does C&D Waste Impact the Environment?

Because of the wide range of materials present on construction sites, the environmental impacts vary significantly.

Landfill Space

In 2018, approximately 145 million tons of U.S. C&D waste were sent to landfills. Materials like concrete and asphalt do not break down over time, meaning they take up valuable landfill space for the long term.

Resource Depletion

Construction projects rely heavily on raw materials such as gravel, sand, and limestone. Continuous extraction contributes to habitat destruction, resource depletion, and increased carbon emissions. When these materials are then discarded instead of recycled, valuable resources are permanently lost.

Greenhouse Gas Emissions

The production, transportation, and disposal of construction materials require significant energy, contributing to greenhouse gas emissions. Additionally, the landfills generate methane, a potent greenhouse gas, further increasing environmental impact.

Soil and Water Contamination

When C&D materials are improperly disposed of or placed in landfills, they can contribute to contamination over time. Certain materials may release harmful substances into leachate — a contaminated liquid that forms within landfills. This liquid can seep through leeks in landfill systems, contaminating nearby soil and water sources. These pollutants can have serious impacts on surrounding ecosystems and negatively affect wildlife.

What You Can Do to Help

To reduce the environmental impact of construction and demolition waste, consider these best practices:

Plan Ahead

Establish waste reduction and recycling practices early in your project.

Use Sustainable Materials

Choose materials that are recycled, recyclable, or have a lower environmental footprint.

Educate Workers

Ensure crews are trained on proper sorting, handling, and disposal methods to maximize recycling efforts.
