The owner of Holiday Inn and InterContinental Hotels is replacing mini bottles of shampoo and other toiletries in hotel rooms with bulk-size bathroom amenities to cut waste, writes Danica Kirka for USA Today.

The transition affects 843,000 guest rooms and will be completed in 2021. The effort reduces plastic waste in the seas.

“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,” said InterContinental Hotels Group CEO Keith Barr.

IHG, which uses an average of 200 million bathroom miniatures every year, said customers expect them to act responsibly.

Public awareness of the problem of plastic waste has been swelling amid alarming forecasts that there could be more plastic than fish in the oceans by 2050.

Where consumers’ attention goes, so does that of companies.

Amcor, L’Oréal, Mars, PepsiCo, Coca-Cola, Unilever, Walmart, and Werner & Mertz are among the companies who have committed to move, where relevant, from single-use to reusable packaging by 2025. according to the Ellen MacArthur Foundation, an innovation think-tank.
