Non-hazardous industrial waste materials include items such as gypsum, coal ash, slag, foundry sand, and various construction and demolition materials. Each of these unique by-products can be recycled or re-used in many different ways. Examples of best-practices in recycling include the following:
plant. Ferrous foundries generate a large 35 years wamount of waste. The Indian foundry produces around 6 million ton of castings annually. The slag produced annually is around 1.7 million, isolation industry. Research and long term experience have it is estimated around 5000 foundries are operating
Ferrous foundries create a lot of waste. The Indian foundry creates around 6 million ton of castings every year. The slag delivered every year is around 1.7 million, it is evaluated around 5000 foundries are working all over India. All foundries produce castings by emptying liquid metal into moulds, commonly comprising of centre and trim sands.
Efficiency of material utilization is vital in any industry – steel mills and foundries are no exception. Recycling and utilizing slag instead of treating it as waste enable cutting costs and generating new revenue.

Spent foundry sands from non-leaded brass foundries and spent foundry sands containing olivine sand also are not evaluated in the risk assessment. In addition to spent foundry sands, foundries can generate numerous other wastes (e.g., unused and broken cores, core room sweepings, cupola slag, scrubber sludge, baghouse dust, shotblast fines).
waste foundry sand and slag is of main significance due to the trivial amount produced from the foundries throughout the world. Steel slag is a waste product produced during steel production. Ferrous and non-ferrous metal casting industries produce several millions tons of byproduct in the world. In
