Frequently Asked Questions

What is CDE Waste?

Construction, demolition and excavation (CDE) waste is the unused or unusable material or refuse of construction activities on any development project (e.g., residential developments, commercial buildings, parking lots, bridges and tunnels, among others).

Examples of CDE Waste Processed:

Why is CDE Waste a real & growing problem?

The number of cities with one million people has grown worldwide, increasing the amount of city and urban construction: This growth is a driver of the increased use and dependency on raw materials, yet also highlights the growing need for CDE waste recycling and reuse. The latter is the sustainable path and future of the industry

What are the benefits of CDE Waste Recycling?

CDE Waste Recycling offers a wealth of benefits to the industry, the community, and the environment at large, including:

  • Maximizes the recycling of construction, demolition and excavation waste
  • Maximizes the production of high quality, high value recycled sand and aggregates which can be used as a replacement for virgin aggregates in a range of construction applications including concrete and asphalt production
  • Ensures the ability to meet the growing demand for sand and aggregates from a sustainable source
  • Protects sand and aggregate supply in areas where natural reserves are in decline
  • Minimizes transport costs for sand and aggregates – recycled materials are typically produced closer to urban centers
  • Reduces the carbon footprint of your processing operation by producing recycled sand and aggregates closer to market
  • Helps to ensure a more sustainable future

Are recycled aggregates expensive?

Recycled aggregates are actually less expensive to produce in comparison to freshly mined materials, in addition to its lower cost to the environment. Local aggregates are also more affordable because it cuts down on the costs required to ship and deliver the materials and reselling aggregate is more cost effective than sending it to landfill.

Can recycled aggregates come close to the quality of virgin, raw aggregates?

Recycled aggregate has actually been proven to be comparable to virgin aggregates, and it can be made even stronger depending on material mix and processing technologies. It’s incredibly reliable as a material and has been found to be structurally sound.

What is a circular economy?

Repurpose Aggregates believes in the circular economy model, in which materials, tools, and systems that are designed to prevent waste are the priority. The circular economy attempts to fundamentally change the linear model of production, which focuses on extraction, manufacture, use, and disposal. Instead, a circular economy model focuses on diminishing energy usage, creating durable materials, and attempting to design waste out of the system. These aim to minimize (or even eliminate) waste and pollution by improving efficiency and keeping products and materials in use. It is a fundamental change in development models that can increase the longevity of our industry and improve our environment at large.
