Hotel groups are phasing out miniature toiletries, in an effort to reduce plastic waste.

InterContinental Hotels Group announced last month that all of its hotels worldwide will replace the mini – shampoo, conditioner and shower gel – bottles with bulk-size bathroom amenities by the end of 2021. Refillable models are currently in approximately 30 per cent of IHG’s estate but the group still distributes 200 million miniature toiletries per year. IHG owns Holiday Inn, Regent Hotels and Crowne Plaza and among other brands.

“It’s more important than ever that companies challenge themselves to operate responsibly – we know it’s what our guests, owners, colleagues, investors and suppliers rightly expect,” said IHG’s CEO Keith Barr in an Associated Press statement. “Switching to larger-size amenities across more than 5,600 hotels around the world is a big step in the right direction and will allow us to significantly reduce our waste footprint and environmental impact as we make the change.”

Marriot International, the world’s largest chain, plans to switch to larger pump-action bottles instead of moving to refillable, wall-mounted dispensers by December 2020. Marriot owns Sheraton, Ritz-Carlton, St. Regis, W Hotels, and Weston to name a few.
