Why Is Construction & Demolition (C&D) Waste Different?
-
Household waste contains food scraps and liquids that break down quickly causing smells and attracting pests.
-
Construction and demolition (C&D) waste is stable, clean, and tested for pollutants before disposal or recycling. It’s ideal for creating recycled, lower-carbon building materials.
