There is an original technology for obtaining high-strength gypsum binder (hereinafter HBV) from phosphogypsum dump (Voskresensk) or waste gypsum production (fraction 0-60 mm). HBV is konsumentem component of a number of dry mixes. Also it can produce gypsum Board, drywall, etc.
In the Moscow region of HBV only imported (from Samara), so expensive (from 8500 rubles/ton). The proposed production line allows to obtain HBV cost less than 4000 rubles/ton. For successful implementation it is also proposed that the structure of production to include lines for gypsum boards and dry building mixtures.
The production of slabs and mixtures of HBV can dramatically increase consumer parameters of products (to increase durability, to reduce weight) at lower prices (there is a possibility to add a cheap foam or inert fillers). It is possible to create new building materials previously impossible because of the high cost of HBV.
The technology was tested in industrial equipment has certificates and hygienic conclusions.
The payback period — 4, 5.5 years (described in the economic rationale)
Please take with a large grain of salt to the easily accessible information from the Internet about phospholipase — 95% this is a populist article to control public opinion.
Phosphogypsum, when used properly, are recommended for processing by Soviet Standards and technical specifications.
