How can you properly segregate waste in your laboratory?

2 Use appropriate containers

The second step to segregate waste in your laboratory is to use appropriate containers for each category of waste and label them clearly. Non-hazardous waste can be disposed of in regular trash bins or recycling bins, depending on the material. Hazardous waste must be collected in compatible containers that are closed, leak-proof, and labeled with the name and hazard of the contents. Biohazardous waste must be collected in autoclavable bags or rigid containers that are marked with the biohazard symbol and the name of the generator. Radioactive waste must be collected in shielded containers that are labeled with the radioactive symbol and the activity and type of the radionuclide.

3 Follow local regulations

The third step to segregate waste in your laboratory is to follow the local regulations and guidelines for waste disposal and recycling. Different jurisdictions may have different requirements and procedures for handling and transporting laboratory waste, depending on the nature and quantity of the waste. Therefore, it is important to consult with your local waste management authority or environmental agency to ensure compliance and avoid fines or penalties. Some common regulations include registering as a waste generator, maintaining waste inventory records, segregating waste at the point of generation, storing waste in designated areas, and arranging for licensed waste contractors to collect and dispose of the waste.

4 Train your staff

The fourth step to segregate waste in your laboratory is to train your staff on the proper waste management practices and policies. All laboratory personnel should be aware of the types and sources of waste that they generate, the potential hazards and impacts of the waste, and the appropriate methods and containers for segregating and disposing of the waste. They should also be familiar with the local regulations and guidelines for waste disposal and recycling, and the roles and responsibilities of the waste generators and contractors. Moreover, they should be able to identify and report any incidents or issues related to waste management, such as spills, leaks, injuries, or violations.

5 Reduce and reuse

The fifth step to segregate waste in your laboratory is to reduce and reuse the amount of waste that you generate as much as possible. Reducing waste can help you save money, resources, and space, as well as minimize the environmental impact and risk of your laboratory activities. Some ways to reduce waste include using microscale or alternative methods, purchasing only the necessary amount of chemicals and materials, avoiding single-use items, and sharing or donating surplus or unused items. Reusing waste can also help you extend the lifespan and value of your materials, as well as reduce the need for disposal. Some ways to reuse waste include recovering and purifying solvents, recycling metals and glass, and composting organic matter.

6 Review and improve

The sixth step to segregate waste in your laboratory is to review and improve your waste management practices and performance on a regular basis. You should monitor and evaluate the quantity and quality of the waste that you generate, the effectiveness and efficiency of the segregation and disposal methods, and the compliance and satisfaction of the staff and stakeholders. You should also seek feedback and suggestions from your staff, contractors, authorities, and peers on how to improve your waste management system. Additionally, you should update and revise your waste management policies and procedures as needed, based on the changes in regulations, technologies, and best practices.
