New Delhi: Seeking to boost inventions, the Council of Scientific and Industrial Research will establish 12 innovation complexes across the country, with the first three coming up at Mumbai, Kolkata and Chennai.

The CSIR Innovation Complexes (CIC) will house scientists from various disciplines with stress on designing commercial products based on indigenous technologies.

Earlier this week, Prime Minister Manmohan Singh approved the establishment of CICs in Mumbai, Kolkata and Chennai within the next two years, CSIR Director-General Samir Kumar Brahmachari said.

Financial clearances have been granted for eight such complexes, he said, adding that CSIR plans to build 12 CICs in the 12th Plan.

Each CIC will be built at a cost of Rs 100 crore and comprise modern high rise buildings to house young scientists from various disciplines.

Besides the three, CICs will also be established in Delhi, Bangalore, Pune, Hyderabad and Ahmedabad.

The CIC in Mumbai is being developed at Lokhandwala in suburban Andheri and has been assigned drugs and therapeutics from novel sources and innovative products, processes and biomedical applications as its research domain.

The Chennai complex will focus on clean energy, green infrastructure and innovative engineering while CIC Kolkata will be dedicated to zero emission technology.

"New areas could be added progressively for respective innovation complexes after due deliberation and assessment," Brahmachari said.

The innovation complexes will have 1,50,000 square feet of space and house about 300 people, a majority of them will be young students.
