Green gypsum for greenfingers

摘要

ENVIRONMENT-FRIENDLY GYPSUM company, Agri Marketing Inc., has produced a new grade of gypsum, marketed under the USA Gypsum brand, which is 100 percent recycled from wallboard. Agri Marketing operates from two facilities in Pennsylvania, USA. One is located in Reinholds, Lancaster county, and a second facility is based in Turbotville, Northumberland county. Depending on state, construction and demolition debris accounts for 25-45 percent of US landfill waste. Of this construction debris, 26 percent comprises wallboard material. Owing to the damaging effects of gypsum-derived sulphate in landfill environments, such as possible groundwater contamination, there has been increased emphasis on recycling waliboard.
