摘要

Wallboard construction waste is typically disposed off in landfills, consuming precious landfill space. It is estimated that about 1 ton of wallboard waste is generated for every 2000 sq ft of new construction. On the other hand, animal manure disposal is one of the major challenges faced by the agricultural farmers. Odor and leaching of nitrogen and phosphorus into ground and surface water are major issues concerning animal manure. The objective of this project was to find a reuse for the waste from the construction industry. Wallboard was combined with animal manure and other ingredients to form a value added product (stabilized manure). The stabilized manure had 50% to 90% less odor emissions than the fresh manure. The leaching of phosphorus was lower by 90%. The stabilized manure has significant environmental benefits. This project shows promising results to reduce the construction waste going to landfills and towards a solution to animal agricultural waste issue.
