Site Description
Location & Size of Site
Howrah foundry cluster is one of the oldest and largest cast iron foundry centers in the country, accounting for around 20% of the total castings produced in the country. A number of these units were closed down by the State Pollution Control Board. Though the industry is trying to clean up its own act by sponsoring research into cleaner technologies, 80% are small-scale operations and may find it difficult to do so without outside assistance, both technical and financial.
