Remove, Reduce, Recycle, Renew, Re-use. These are five of the original 7 R's of Sustainable Packaging revealed by Wal-Mart when it introduced its Packaging Scorecard to a standing-room only audience at Pack Expo 2006. The mega-retailer has since shortened the list to reduce, reuse and recycle, but also added a new term, rethink, to encourage companies to always remember to consider smarter sustainable options.
To better understand sustainable packaging, we need to understand what sustainability is and how it's different from the focus in the 1970s on the environmental aspects and impacts of packaging.
Sustainability surfaced in packaging vernacular in 2006, after publication of "The Triple Bottom Line: How Today's Best-Run Companies Are Achieving Economic, Social and Environmental Success - and How You Can Too" by Andrew Savitz with Karl Weber, which Amazon.com describes as "the groundbreaking book that charts the rise of sustainability within the business world and shows how and why financial success increasingly goes hand in hand with social and environmental achievement."
This broader look expands on packaging's previous environmental-only focus to include the business (economic) and social aspects (such as ethical material sourcing and manufacturing conditions).
The basis for sustainable packaging started during the environmental movement in the 1970s. Americans celebrated their first Earth Day in 1970, and became aware of some of our ecological problems such as pollution and littering through various media outlets. One of the most powerful messages came from The Crying Indian anti-litter commercial from Keep America Beautiful.
The finger-pointing at packaging as the main culprit of the country's ecological problems didn't happen in force until the late 1980s. That's when the Garbage Barge became a media sensation. Piled high with trash from Long Island residents, the Mobro 4000 barge left New York City on March 22, 1987, initially headed for a landfill in the southern U.S. But the load was refused there, and at other ports. As Chaz Miller wrote in 2007 for Waste 360, "The economy was hot, and news was slow. Garbage, which is just the effluence of our affluence, was the perfect target. Greenpeace, Phil Donahue and Johnny Carson all used the barge as fodder. Six months after it sailed, the garbage barge's trash was burned in a Brooklyn incinerator, and the ashes buried back in Long Island. The media didn't attend the funeral."
Thus began a concerted effort to reduce the volume of trash by increasing recycling rates of used packaging in the U.S. Efforts to establish an economically viable infrastructure for various packaging materials and engage all stakeholders continue to this day.
While sustainable packaging isn't a difficult concept to understand, it is complex. Is it replacing a rigid container with a pouch? Is it removing a carton and letting a toothpaste tube stand on its own on a shelf? Is it creating one bulk pack instead of multiple single-serve items? Is it using PET instead of PVC because PET can be easily recycled? Is it changing from a round to a square container to be more cube efficient? Is it faster set-up times on the packaging line to minimize the amount of product and packaging waste? Yes, it's all of this - and more.
Sustainable packaging is no longer focused on just recycling. Just as packaging is not the only eco target, although it is still top of mind for many. Right or wrong, packaging is frequently scrutinized and used as the measure of a company's overall sustainability, even though it may contribute only a small percentage to the total eco impact compared to other things, such as transportation, and water and energy use.
The idea of looking at the entire life cycle of a package - from raw materials all the way through disposal - gained ground in the early 2000s. But much of the focus remains on end-of-life.
In an exclusive interview with Packaging Digest in 2013, Jim Hanna, director, environmental impact, Starbucks Coffee Co., explains, "Consumers, especially in the U.S. and Canada, define sustainable packaging by focusing on end of life. That's caused us to focus a lot of effort and resources into creating solutions for our packaging because we know that's what resonates most with our customers."
But in seeking the broader, more encompassing definition of sustainable packaging, most packaging professionals refer to the Definition of Sustainable Packaging developed by the Sustainable Packaging Coalition in 2005:
