Bhushan Steel has put its proposed Rs 20,000-crore steel plant project in West Bengal on hold, stonewalled by the Mamata Banerjee government's policy of not acquiring land for the industry, a senior company official said. “Land acquisition in the state is an uphill task for industries, we cannot do it alone. It is difficult for us to acquire such a vast area on our own,” the company director (finance) Mr Nittin Johari said.
