Other important industries of the region are paper, match, glass, cement, furniture and plywood industries.
The region is experiencing the problems like sickness of mills, shortage of power and political turmoil (Jharkhand Mukti Morcha etc). This has slowed down the growth rate. Being the centre of metallurgical and heavy industries (called Ruhr of India) its importance is bound to grow in future as well.
