Toxic waste
PAKISTAN is advancing in research, science and technology. It has numerous laboratories dealing with biological, material and chemical stuff that often has hazardous substances. A significant amount of toxic waste containing acids, chemicals, grease and oils is being produced in these labs. This waste has occasionally been disposed of improperly that can damage the environment.
Proper handling of laboratory waste is of core importance for environmental safety. Improper handling of such waste can cause water pollution and waterborne diseases as the pollutant enters the sanitation system. Moreover, it contributes to solid waste and air pollution. The liquid waste may block the drains resulting in sewage malfunctioning.
The government should devise a national laboratory waste management plan to handle all waste produced inside the laboratories. A licensed disposal facility with proper transportation system should be employed for this purpose.
Each category of waste should be addressed differently as per its packaging requirements. Well-labelled and leakage-proof containers should be placed inside each laboratory to collect waste separately. It will avoid intermixing laboratory waste with other waste materials.
These containers, after having been properly labelled and sealed, should be transported from each laboratory to a temporary storage site. It should later be taken away by a licensed waste management agency for proper dumping.
Prolonged storage of waste in residential areas should be avoided. All the managers and staff involved should be given proper training to reduce possible dangers. Documentation and record-keeping of waste should be encouraged.
In a nutshell, proper waste management practices will be helpful in reducing pollution, conserving natural resources, and minimising environmental harm. It will also help us accomplish the targetted Sustainable Development Goals (SDGs).
