Now that the hotel industry has largely embraced bans on plastic straws, one major hotel group aims to eliminate the next set of plastic targets: mini bottles of shampoo, conditioner, lotion and the like.

On Tuesday, July 30, IHG will announce it plans to replace all “bathroom miniatures” with bulk supplies across all of its 17 brands, including Holiday Inn Hotels and Resorts and InterContinental Hotels & Resorts. The decision will affect 843,000 guest rooms in more than 5,600 hotels during 2021.

“Today’s customers and colleagues expect us to have less impact on the environment,” said Keith Barr, the chief executive of IHG. He called the company’s plastic straw ban, which was announced in October 2018, to be a first step in a wider sustainability program . “This, to me, was the next logical step.”

While IHG is the first company to issue the brand-wide ban, many hotels already use refillable dispensers of personal care products, often associated with affordable hotels, rather than single-use items.
