Comparison of Life Cycle Environmental Impacts between Natural Gypsum Board and FGD Gypsum Board

This paper gets two inventories of environmental load of two kinds of gypsum plasterboards by studying the production processes of the natural gypsum board and flue gas desulfurization (FGD) gypsum through life cycle assessment. The results show that the total life cycle environment load of the natural gypsum board is 6% higher than the FGD gypsum board. Human toxicity effect increases by 72% and the consumption of non-renewable resources is 76% higher than the total life cycle environment load of natural gypsum board.
