Waste treatment
Inactivation is a strategy for minimising waste, which reduces risk, improves safety and protects the environment. Biological wastes can be inactivated by physical or chemical methods.
| METHODS | TYPES OF WASTE | |
|---|---|---|
| PHYSICAL |
- Moist heat (autoclave) |
- Solid and liquid cultures - Diagnosis samples - Thermoresistant material - Plants |
|
- Dry heat (incineration) |
- Experimental animals - Pathology specimens - Human remains - Specimens with prions - HEPA filters |
|
| CHEMICAL |
- Chlorine and derivatives |
- Liquid cultures in small quantities - Contaminated surfaces and equipment - GMO seeds - Biotoxins |
|
- Alkalis (>pH11) |
- Liquid effluents |
|
|
- Alkaline hydrolysis |
- Animal corpses |
