Most of us will get along just fine without throwaway plastic in our daily lives. But there are nevertheless many legitimate applications for single-use plastics.
Take medicine, for example, where single-use plastics are a key part of infection control. Having a blood test requires gloves made from plastic, a plastic syringe, and a plastic vial, all of which are single-use to control contamination and infection. While glass is often suggested as an alternative, this introduces challenges in cleaning, transport and availability, particularly in emergency situations where resources may be limited.
Single-use plastics also play a role in scientific research. Many scientists cringe as they look at their waste bin at the end of a session in the lab. Typically, it will be filled with pipettes, gloves, vials, sample bags, and the list goes on.
These items are used for their strength and resilience, and because they prevent cross-contamination of sampling. As with medical applications, many substitute materials do not provide the protection or stability that single-use plastics do.
