Lithuanian scientists have invented a method of producing increased strength plaster entirely from waste

(Kaunas University of Technology) Group of scientists at Kaunas University of Technology (KTU) Lithuania have discovered a method of producing increased strength gypsum binding material using only industrial waste products. By combining phosphogypsum -- fertilizing production waste, zeolite -- a waste product from oil refining industry, and an activator, they have casted gypsum stone, which is twice stronger than usual.
