Why are plastic syringes not being recycled?

Body

Billions of plastic syringes are discarded every year: in high-income countries, most are incinerated, while in low-income regions open burning remains common - both methods releasing harmful pollutants and contributing to ecological degradation. Despite the sheer volume of waste, recycling efforts are minimal due to contamination risks, complex waste streams, and limited recycling infrastructure. This essay (part of a series) calls for urgent innovation in syringe design (e.g., recyclable materials), enhanced waste management systems, and global policy reforms. Without these changes, the healthcare sector’s reliance on disposable syringes will continue to pose a serious threat to environmental and public health.
