Laboratory Waste Disposal Best Practices and Etiquette
Lab trash is garbage created by laboratories in a number of sectors as well as educational institutions such as schools and universities.
This garbage may be divided into several categories:
Clinical, biological, electrical, and laboratory hazards
A considerable amount of laboratory solid waste is expected to be non-hazardous waste. Paper, tissues, disposable gloves, packaging, rinsed plastic-ware, rinsed glass-ware, and rinsed out chemical bottles (which must be rinsed at least three times and have their labels damaged) are often regarded as non-hazardous. Detrimental waste contains chemicals that are hazardous to human health or the environment. Hazardous trash must not be disposed of in the regular waste stream or down the drain; rather, it must be isolated, processed, and disposed of by a hazardous waste management service. It is the responsibility of all laboratory personnel to guarantee the safe and proper disposal of all laboratory wastes generated during their work. Chemical waste disposal that is improper or reckless, such as down sewers, in regular dumpsters, or into the atmosphere, is illegal and can have serious effects on human health and the environment.
Best practices for reducing lab waste
Before considering how to dispose of chemical waste, you should look at the laboratory’s internal procedures to determine if there are any solutions to decrease waste. You may achieve this by looking at purchase methods. For example, you can purchase only what is required, eliminating waste due to expiration. You might also look for a dependable provider that can supply modest quantities of chemicals quickly. Another strategy to reduce waste is to consider a centralized buying scheme. to take advantage of bulk prices. Furthermore, it may be beneficial to segregate waste into multiple streams for treatment, reuse, or disposal.
best strategies for reusing lab waste.
Reusing something is frequently the most effective way of decreasing waste. This also applies to laboratory waste. Incorporate recovery efforts into your studies or consider a chemical swap with other institutions in your region that may be able to use your leftover chemical products. If reuse is not an option, all trash should be separated based on chemical incompatibilities, such as hazardous and non-hazardous wastes. The same may be said for organic and inorganic trash. Waste of the same material type can be separated, and waste streams that can be recycled should be stored separately.
Recycling of Laboratory Waste Best Practices
General laboratory waste that has been or may have been contaminated must be treated to ensure its safety (using an appropriate method)before recycling.
All waste should be separated based on chemical compatibilities, such as hazardous vs. non-hazardous wastes and organic vs. inorganic trash.
Make sure the recycling container is clearly labeled by placing a label on it, and that dangerous trash, such as chemicals, is not placed in it.
Hazardous material collecting bins should be put in the lab. These should be emptied on a regular basis and monitored by lab personnel.
Containers (e.g., cans, bottles) that formerly held chemicals or other hazardous items should be cleaned and made safe for disposal where suitable and safe. It is important to declare that the container has been made safe by removing or defacing the contents label in certain cases. Clean recyclable material which has been recognized clearly as non-hazardous should be recycled using proper containers.
Waste streams that may be recycled, such as recoverable metals or solvents, should be kept separate.
How to Dispose of Laboratory Waste
Chemical waste disposal requires three steps: packaging, labeling, and storage.
Packaging Laboratory wastes must be stored in containers that are suitable for the chemicals contained, and containers should only be filled to 75% full to allow for vapour expansion and to avoid spillage that can occur when transferring overfilled containers. Chemical waste must not be packed in containers that incorrectly label other non-existent risks. Glass containers have historically been considered the most chemically resistant, although they are brittle. Metal containers are more durable than glass ones. However, their contents frequently corrode them. Chemically resistant plastic containers are increasingly being preferred over glass or metal containers. Metal or plastic safety cans should be considered for storing flammable chemicals. Incompatible materials should never be combined in the same container. Solvent safety cans should be used to collect and temporarily store significant amounts of flammable organic waste solvents (10–20 litres). Precipitates, solids, and other non-fluid waste should not be combined in safety cans. Because the melting point of lab glassware is greater than that of regular glass, it cannot be recycled. Technical staff should collect broken glassware in puncture-proof containers and dispose of it in big containers. Biological waste such as agar plates, dissection debris, and so on should be separated and collected independently This can be autoclaved if necessary.
Labelling All containers must be labeled with the group name from the chemical waste category as well as an itemized summary of the contents, allowing experienced laboratory employees to assess the hazard. When collecting suitable trash in a shared container, make a note of the components to aid in future disposal decisions. All garbage must be properly wrapped with clear and permanent labeling. Sharp objects, like syringes and scalpel blades, should be stored in containers labeled “Sharps.”
Storage Chemical waste storage containers must be in excellent condition and must stay closed unless waste is added. Hazardous waste should be carefully kept before being removed from the laboratory and should not be allowed to accumulate. Incompatible hazardous wastes, such as acids and bases, must be separated. All liquid waste must be kept in leakproof containers with a screw-top cover or other tight closure. Transfer garbage to a container that can be tightly closed if necessary. Spills and leaks from the primary container should be captured using secondary containment.
