Fast-food chicken chain KFC said Thursday that all plastic-based, consumer-facing packaging will be recoverable or reusable by 2025. Walmart Canada announced plans on Wednesday that include reducing plastic bag use by 2025 that will take about 1 billion bags out of circulation, and replacing single-use plastic straws with paper alternatives by 2020.

“This commitment represents a public acknowledgment of the obligation we have to address these serious issues” of environmental sustainability, KFC Chief Executive Officer Tony Lowings said in a statement.

Waste from plastic has become a flashpoint with environmentalists and consumers, and companies are reluctant to be seen as falling behind. Oreo-maker Mondelez Internationaland Nestle are among food giants that announced similar sustainability goals last year. KFC parent Yum! Brands previously said it will source all fiber-based packaging from certified or recycled sources by 2020, as a supporting partner of the NextGen Consortium. Starbucks Corp., McDonald’s Corp. and Coca-Cola Co. are also partners.

Walmart Canada, with 411 stores and more than 85,000 employees, announced additional goals, including a 2025 target to have 100 percent recyclable, reusable or compostable packaging for its own private brand products as part of a global commitment launched by The Ellen MacArthur Foundation in 2018. Thus far, more than 290 companies have signed on for the 2025 date.

“This is an aspirational goal when you think about it,” said Conrad MacKerron, senior vice president of As You Sow, a nonprofit group focused on shareholder advocacy. Still, publicly committing to such a target helps investors and consumers hold companies accountable, MacKerron said.

Nestle and PepsiCo are among some 25 consumer companies taking part in a program announced Thursday at the World Economic Forum in Davos, Switzerland, that provides products in reusable packaging that can be returned for a refund. The Loopinitiative, which refers to a theoretical circular economy where nothing is wasted, is led by New Jersey-based recycling company Terracycle.

KFC also said Thursday it made good on a promise that by the end of last year all chicken purchased would be raised without antibiotics important to human medicine. That initiative got underway in 2017 after pressure from shareholders.

Other fast-food chains began phasing out chicken with antibiotics years earlier. Chick-fil-A began in 2014, Subway eliminated it in 2016 and Taco Bell, also owned by Yum! Brands, reached the goal in 2017. Still, KFC helped tip the chicken industry in an important way, according to Lena Brook, director of food campaigns at the National Resources Defense Council.

“KFC proved that even in perhaps a more complex reality that change is possible if you commit to it,” Brook said.
