Marriott International is planning to eliminate single-use toiletry bottles of shampoo, conditioner, and bath gel in all hotel rooms. The hotel brand will be replacing the toiletries with larger, pump-topped bottles.

Marriott began testing the change in the last few years, and currently has larger bottles in around 1,000 properties in North America. They expect to complete the change in all their hotel brands by December of 2020. The hotel brand expects to prevent about 500 million tiny bottles, or 1.7 million pounds of plastic, from going into landfills each year.

“This is our second global initiative aimed at reducing single-use plastics in just over a year, which underscores how important we believe it is to continuously find ways to reduce our hotels’ environmental impact. It’s a huge priority for us,” said Arne Sorenson, President and Chief Executive Officer of Marriott International. “Our guests are looking to us to make changes that will create a meaningful difference for the environment while not sacrificing the quality service and experience they expect from our hotels.”

Marriott said they usually see about 1 million guests every night. Five Marriott brands are already using the larger bottles in hotel rooms, including Courtyard by Marriott, SpringHill Suites, Residence Inn, Fairfield by Marriott and TownePlace Suites.
