🏗️ The Demolition Data Gap

In the United States, construction and demolition waste (CDW) accounts for roughly 67% of the total solid waste stream, with a staggering 90% originating directly from demolition sites. For a transition toward a circular economy, accurately estimating the recoverable portion of this waste is crucial. Yet, traditional estimation models remain heavily focused on total volume rather than recyclable potential.

♻️ Breaking the Linear Fate

In the built environment, every structure has a life cycle—from natural resource extraction to final disposition. Unfortunately, the vast majority of waste generated at the end of a building's life meets a "linear fate," terminating in landfills. To achieve a truly circular economy, we must continuously extend the life of materials through Reduction, Reuse, Repair, Recycling, and Recovery (the 5Rs).

Paving the Way to Sustainability: Recycling Construction Waste for Urban Roads

♻️ The Growing Crisis of Construction Waste

Every year, nearly 50% of the raw materials extracted globally are consumed by the construction industry. Simultaneously, the demolition and renovation of urban infrastructure generate massive amounts of Construction and Demolition Waste (CDW). Finding sustainable ways to repurpose this waste is critical for reducing environmental degradation and achieving true sustainable development.
