RIYADH: As millions of Muslims gather in Makkah for Hajj, concern is growing over the environmental toll of one of the world’s largest annual religious gatherings — particularly the vast quantities of plastic waste left behind.

From water bottles to shopping bags, single-use plastics are a staple at major public events, and Hajj is no exception. Given the sheer volume of pilgrims, this waste can have lasting environmental consequences, unless mitigated by more sustainable choices.

Fortunately, awareness is growing among individuals and organizations about the harm caused by plastic pollution. Many are now turning to greener alternatives to reduce their footprint during the holy season.

Among the most commonly used items are plastic water bottles. With millions expected to be discarded during Hajj, experts and advocates say it is important to replace single-use items with reusable options or eliminate their use altogether.
