Chemplast Sanmar Limited

Where integration is the key

Chemplast Sanmar – over forty years old and the flagship company of The Sanmar Group – is a major manufacturer of PVC resins, Caustic Soda, Chlorochemicals, Refrigerant gas and Industrial Salt. The manufacturing facilities are located at Mettur, Cuddalore, Panruti and Vedaranyam in Tamil Nadu and Karaikal in the Union Territory of Puducherry.

The commissioning of a PVC project at Cuddalore, Tamil Nadu, has been a major step forward for the Group. The facility commissioned in September 2009 has an annual capacity of 2,21,000 tons, the largest chemical project to come up in the state of Tamil Nadu for well over a decade. Chemplast Sanmar’s aggregate capacity of 2,92,000 tons makes it one of the largest PVC players in India.

At Chemplast, integration – forward and backward – is the key. The basic feedstock for its PVC plant at Mettur, alcohol and chlorine, comes from its industrial alcohol plant at Panruti and chlor-alkali facilities at Mettur and Karaikal.

The Chlorochemicals division of Chemplast, a result of backward integration by the Group, manufactures a wide range of products using a highly integrated manufacturing process. These downstream products are either chlorine derivatives or chlorine users in the production process.

The salt needed for chlorine manufacture is supplied by Chemplast’s salt fields at Vedaranyam. The power-intensive electrolysis process of manufacturing chlorine is served by Chemplast’s own power plant.

All this makes Chemplast one of the most integrated chemical plants in the country with a closed manufacturing loop. Its product range falls into five distinct Groups — PVC Resins, Caustic Soda / Chlorine, Chlorinated Solvents and Refrigerant Gases.

Chemplast has thus played a pioneering role in the field through its ingenious choice of feedstock and manufacturing processes, and efficient, eco-friendly practices. Its constant development of environment-friendly production processes has reduced the consumption of valuable natural resources.
