Recycling is an important aspect of waste management, but it can be challenging in laboratory settings due to the complex nature of handling waste materials. Consumables used in labs are often contaminated with chemicals, biological materials, or other hazardous substances, requiring strict guidelines and procedures for their proper disposal. Disposal procedures may vary depending on the type of waste material and different laboratories use different products, making recycling even more challenging. In addition, space limitations, costs, and the need for internal engagement in waste segregation can also present challenges.
Despite these obstacles, MPL Laboratories is committed to finding waste management solutions. In October 2022, Kira Morgan and Sebastian Moran spearheaded the introduction of a trial program, the TerraCycle® Filtration Device recycling program, focused on syringe filters and syringes used in the sample sorting room. In the program's first three months, 92kg of syringes and filters were successfully recycled, marking a significant achievement.
It's important to note that the recycling program is currently limited to a specific area of the laboratory. Consumables used in other parts of the lab that contain acids, solvents, or other hazardous materials cannot be recycled at this time due to safety concerns. Even plastic bottle recycling is challenging in a laboratory setting because incoming samples received by the lab are often unknown and could be contaminated. Some of these contaminants could leach into the plastic and then be processed into new items, which can impact human health and environmental safety. In some cases, local regulations and recycling facilities may prohibit the recycling of certain items due to these safety concerns, making plastic disposal even more challenging. Consequently, much of this waste still ends up in landfills.

While creating a more sustainable laboratory environment cannot be achieved overnight, continued exploration of innovative solutions is a start. The team's passion for environmental awareness and action has been instrumental in driving the initiative. Commenting on the program, Kira explained, “At home, I try to recycle and volunteer for beach clean ups when I can. So, at work, I’m always on the lookout for ideas – even the smallest changes that we can make for a difference.”
With the program still underway, special thanks to Meredith Conroy and the Sample Receipt team for their contributions. Based on the success of the trial, the program may be expanded to other company locations.
About the TerraCycle® recycling program
Prospective participants in Australia can learn more and sign up to TerraCycle’s recycling program by creating an account and commencing the collection of waste. Once collected, a prepaid shipping label is affixed and then sent for recycling.
