Landfills pose health and cost problems for governments and organizations charged with the disposal of public and industrial waste. Waste drywall takes up a tremendous amount of space in landfills, reducing their lifespan. This is a significant problem in many jurisdictions worldwide.
Approximately 30 million tons of wallboard is manufactured in North America each year, and in spite of the fact that it is recyclable it is still being disposed of in landfills. Overall, it is estimated that scrap gypsum represents approximately one percent of the total waste stream in North America, and comprises up to 15 per cent of construction and demolition debris. The North American industry’s rule of thumb is that drywall scrap will equal one pound per square foot of floor area, or about one ton per average house.
