How many plastic shampoo bottles are thrown away?

The number of shampoo bottles thrown away annually is significant, contributing to the broader issue of plastic waste. Estimates vary, but it's believed that billions of shampoo bottles are discarded each year globally. 

Globally, the figure is much higher, running into several billions, considering the widespread use of shampoo and the reliance on plastic packaging.

This vast amount of plastic waste poses serious environmental challenges, particularly given the long time it takes for plastic to decompose. Many efforts are underway to address this issue, including increased recycling initiatives, the development of biodegradable packaging, and the promotion of refillable or bulk options for consumers.
