Composting of Clean Gypsum Wallboard Scraps (1997)

Summary:

Composting operations require dry bulking agents. Recycling scrap gypsum wallboard (with the wallboard paper intact), as a bulking agent in a composting process, proved to be a viable end use application for this construction waste stream. Product end use, process control, and grinding optimization efforts are important factors affecting successful incorporation of wallboard into a compost operation, and yielding high compost quality.
