The activities are centred around the development of novel cost-effective processes of improving quality & yield of solar salt and for the recovery of valuable marine chemicals like potash and magnesium chemicals. We create value addition in solar saltworks through bittern and saline waste management, recovery of freshwater, the greening of salt works and maximization of solar energy usages. The division has expertise in land survey, design & layout of salt works. We are also conducting various training programs to generate skilled manpower to cater to salt industries.
Skill Development Programs:
The division is conducting periodic training programs for salt manufactures and salt officials at various levels to educate them to produce good quality of salt in field. Recently we have also started a “Certificate Course in Solar Salt Technology” under skill India initiative of CSIR-CSMCRI with an objective to cater trained people to salt and salt based industries which will indirectly improve salt production of India (both quality & quantity) by adopting scientific approach by trained persons and will create self-employment.
