Why use incinerators?

These are the reasons why they are used:

1. To destroy contaminated or putrescible waste hygenically (Hospitals, Abattoirs, Mine Hostels).
2. To recover precious metals from waste (Reduction Works and Refineries).
3. To ensure destruction of condemned waste (Municipalities, Health Departments).
4. To prevent pilferage of merchandise by concealing it in the waste for later collection (Manufacturing Industries and Commerce).
5. To destroy confidential documents and maps (Post Office and the Defence Force).
6. To reduce cost of waste removal (Commerce and Industry).
