The advantages of incineration are "" - The volume and weight of the waste are reduced to a fraction of its original size.
- Waste disposal is immediate.
- Waste can be incinerated at site.
- Air discharge can be effectively controlled.
- The ash produced is sterile.
- Complete destruction of most hazardous material is also possible.
- Small area is required.
- By heat recovery cost of operation can be reduced.
Some of disadvantages are - High capital cost.
- Requirement of skilled operators.
- All materials can not be...
