Waste management in a lab environment has many aspects. Types of waste include:
- Broken or redundant equipment
- Paper (for documents or hand towels)
- Chemicals, particularly liquids
- Heavy metals
- Biological waste
- Glass
- Sharps including syringes and related clinical waste
- Plastics: PET, HDPE, polystyrene, rubber etc
- Water (tradewaste)
- Recyclables
Waste auditing
To get accurate information and data regarding waste management, a waste audit is recommended. This involves segregating the contents of a typical bin and measuring the waste types and volumes. With this baseline information you can prioritise what you want to do with waste.
Waste Hierarchy
The waste management hierarchy is a tool to drive waste management decisions. It involves consideration of the following steps:
1. Waste avoidance (don't create it to start with)
2. Waste reduction
3. Waste reuse e.g. reuse of grey water
4. Recycling
5. Recovery e.g. methane into power from sewerage, metals from electronic waste
6. Treatment e.g. sterilising clinical waste
7. Disposal - the last resort!
Applying a waste type to the hierarchy will give the preferred management method, but the overall goal should be to eliminate.
