The pollution norms differed state to state and created problem in the functioning of industries, which affected the continuity, since the licence was renewed every year, Swaminathan, Chairman of organising committee of 64th Indian Foundry Congress, to be held here from January 29, told reporters here.
The region being number one in the Country, with 600 units, was facing the problem of pollution as the sector was placed in red category.
However, almost all the industries have modernised and installed latest technology to control the pollution, he said.
Another major problem being faced by the industry was huge gap of manpower, Nithyanandan Devaraj, Chairman, Southern Region, Institute of Indian Foundrymen, the organisors of the congress, said, adding that the sector was managing with the migrant workes from Odisha and Bihar, who stayed for 11 months.
The foundry production in India has crossed 10 million tonnes and occupied third place in the world, with 15 to 20 per cent exports, he said.
