Major hotel chains are starting to slowly phase out tiny plastic bottles for items like shampoo and conditioner. Now, hotels in the nation's most populous state, California, will have to stop offering single-use plastic amenity bottles under a law that was just signed.

California governor Gavin Newsom signed the bill into law last week. In 2023, hotels with more than 50 rooms will have to comply with the law sooner.

However, hotels with fewer than 50 rooms will have an extra year and won't have to comply with the law until 2024. Hotels that violate the law will have to pay a $500 fine for the first offense and $2,000 for each subsequent offense.

The law is even supported by the California Hotel and Lodging Association, so it appears that tiny plastic bottles in California hotels are on their way out, for good.

Some of the world's largest hotel chains are also changing on their own. Marriott International plans to get rid of small plastic bottles for all its hotel rooms by December 2020. IHG, which owns Holiday Inn and other large brands, will get rid of plastic bottles sometime by 2021.

Hotel chains aren't the only ones trying to kick the plastic habit. Last month, Alaska Airlines launch ed an initiative called 'Fill Before You Fly', which encourages flyers to bring their own water bottle when traveling. Travelers can fill their bottles before boarding the plane instead of relying on purchasing bottles of water. Also, in August, San Francisco International Airport banned the sale of water in plastic bottles.
