4R principle  =  Reuse,  Reduce, Recycle, Recover ...substances and energy from waste...

The 4R principle is the waste management principle.  That is very good as waste is properly recycled or burnt and removed from the communities properly.  This reduces unhygienic conditions..

Energy is obtained by burning waste to get thermal energy.  Oil is made from certain rubber type substances.   Using anaerobic digestion process,  energy is obtained.  Thus money is also earned from waste.

Certain elements like paper, glass substances could be recycled very easily.
