The phosphate industry found at least one regular consumer of one of its waste products called silicofluorides. Municipal water treatment facilities used this waste product and based on recent estimates; the phosphate industry sells approximately 200,000 tons of silicofluorides (hydro-fluorosilicic acid & sodium silicofluoride) to US communities each year for use as a water fluoridation agent, (Bromwell and Carrier, Inc.). 200,000 tons of this particular phosphate waste is a small amount relative to what is produced in the mining process overall.
GRG is also versatile in terms of available finishes. Gypsum elements can be painted with flat latex, or they can be crafted to have a wood grain texture or look like copper, aged bronze, or sandstone. Glass Fiber Reinforced Gypsum is fire resistant: Gypsum, one of the main ingredients in GRG, is a mineral that will not burn.

Manufacturers, in trying to find a way out of the situation, have invested in technological equipment which isn’t suitable for the Russian market, and this leads inevitably to an inability to set up normal manufacturing. Yet even so, there is excellent Russian-developed technology, including much which is available for instant application. The most important of these developments have received Russian and international recognition, particularly research carried out by MGSU into the development of water-resistant gypsum binders which outstrip rival products produced abroad. These include.
The shaft ceiling shall be framed and sheathed on exterior and interior as the walls (see above). It shall be enclosed by not less than 1 door at each stop, which door shall be not less than 1-hour fire-rated, self-closing, shall be self-latching, and smoke-sealing.
Within the cab, there shall be not less than 1 dry-chemical, portable fire extinguisher rated not less than 2A:10B:C mounted at 3’-6” above finish floor level to carrying handle.
