• Get energy audit done periodically to identify conservation opportunity and opimising energy use efficiency.  

• Provide top cover to the furnace. (Foundry)
        

• Control of pouring temperature of molten metal. (Foundry)   

• Increase bulk density of the charge (scrap metal) by using press.(Foundry)
   

• Oxygen lancing in cupola. (Foundry)

• Use heat recovery from flue gas. (Foundry)

• Provide insulation to oven to reduce surface temperature.
    

On site reuse or recovery:

• Identify recovery materials that can be segregated at generation.
       

• Consider in plant recycling of recoverable materials directly recycle the material back into the original production process.

• Application of black liqupr (from sulphite pulping) as fertiliser.
   
• Application of screening rejects in board manufacture.
   

• Preparation of utensils cleaning powder from waste liquor of kier (textile) and ash from coal fired boiler. (Textile) 

• Use of cloth rags for mattress making.  (Textile)
   
• Use of cashewnut shell oil as coating for corrosion prevention.
