Industrial Chemicals
The by products that are being generated in various process plants such as Phosphoric Acid Plant, Sulphuric Acid Plant are value added and marketed as Industrial inputs which are utilized in Cement and Aluminium Industries, Detergents & other chemical processing industries.
SPIC Gypsum : Phospho Gypsum – Industrial Grade
SPIC Gypsum is a by-product from Greenstar’s phosphoric acid manufacturing plant.
Product Applications
Agricultural use: Gypsum works as an agent to remove saline or alkaline ingredients in the soil and acts more or less like manure.
For industrial use: Gypsum is used to manufacture Gypsum boards. In the cement industry, gypsum is used to manufacturing lime. Gypsum is also used in manufacturing Plaster of Paris.
Product Specification
SPIC Gypsum is an ideal soil conditioner and a rich source of calcium (23%) and sulphur (18%). CaSO4, 2H20 90%, T – P2O5 0.50 %
Soda Ash
Soda Ash, technically termed Sodium Carbonate, is one of the basic industrial chemicals which has increase in demand of 8% per annum. Sodium Carbonate finds extensive application in various industries - Soaps & Detergents, Glass, Silicates, Dyes & Dyestuffs, Bichromate, Textiles and other products including House cleaning and Petroleum refining agents
Owing to the adherence to the stringent quality control measures, TFL's Soda Ash is rated the best in the industry

Ferrous Sulphate
Karpaga Vinayagar Marketing & Transport Company is the major marketing company of copperas as a by-product, with over shadow short of two decades experience supplying to various user industries.
- Ferrous Sulphate Heptahydrate, also calledcopperas,is a blue-green, monoclinic crystals; soluble in water, melts at 64 C.
- Commercially generated as by-product during the manufacture of Titanium Dioxide.
- Even though Ferrous sulphate is a by-product we have fully mechanised facility exclusively to manufacture FSH with min. 99% Purity.
- Used as a mordant in dyeing wool, in the manufacture of ink, in water purification as a substitute for aluminum sulfate, as a fertilizer, and as a feed additive.
- Copperas is also widely used as a coagulant in water treatment chemicals, and as a raw material for iron oxide pigments.
