How we can recycle resources and wastes?
The waste resources need to go waste, they can be used. The process of revising these waste minerals is known as recycling. Scraps and fused metals are produced in huge amount in factories. These metals can be melted and recycled for useful purposes. Waste water which is rich in organic nutrients can be reduced for irrigation purposes after making it free from germs and poisonous elements. For this waste water is treated in a tank. Solid wastes like cattle dung, garbage, etc. are being used for produced cooking gas. Slag is a waste product of metal can be powdered and added to the cement for construction. Thus the solid wastes are very useful resources for providing raw materials to our industries.
