Marriott recently announced it is replacing travel-sized toiletries — tubes of shampoo, conditioner and bath gel — with larger bottles in an attempt to reduce plastic waste.

The world’s largest hotel chain said the small toiletries being used aren’t usually recycled. The new bottles will be made from recyclable materials.

Once the change is fully implemented, the hotel chain said it expects to reduce its plastic disposal by 30%, or nearly 2 million pounds of plastic it sends to landfills annually.

The change will affect roughly 500,000 guest rooms and will be made at most of its 7,000 hotels around the world by December 2020.
