Plastic Economy Report Highlights Continuing Push toward Sustainable Packaging Materials

By 2050, the world’s oceans could have more plastic, by weight, than fish—if something is not done about it.

A coalition of industry players intends to do something about it.

The Ellen MacArthur Foundation, in conjunction with the World Economic Forum and McKinsey & Co., has developed the concept of the New Plastics Economy. It is part of a wider, multi-industry, global initiative called MainStream,  which aims to accelerate business-driven innovations and help further the circular economy. Partners in the New Plastics Economy concept include major producers and users of plastic packaging such as Coca-Cola, Danone, Mars Inc., Amcor and Veolia.

The MacArthur Foundation debuted the New Plastics Economy in a 2016 report. An updated version, released this year, includes a concrete, comprehensive plan of action that encompasses the complete plastics supply and use chain, in all parts of the world.

“We urgently need to transform global plastic packaging material flows if we are to continue to reap the benefits of this versatile material,” says Paul Polman, CEO of Unilever. “This report marks a major milestone, calling out specific actions to capture opportunities for redesign and innovation, reuse, and recycling. It’s now up to us all to get it done.”

The Challenges of a Circular Plastics Economy

The report begins by acknowledging the challenges of establishing a true circular economy in plastics. Only 14 percent of plastic packaging is collected for recycling globally, and the cost of collecting, sorting, and recycling packaging usually outweighs the revenues it generates directly.

The report identifies several strategies to meet these challenges. Broadly speaking, they are:

Redesign: By redesigning the materials, formats, and delivery models of problematic packaging like small-format packages, one of the greatest obstacles to the New Plastics Economy could be eliminated. Without this, the report estimates, some 30 percent of plastic packaging will be never be reused or recycled.

Reuse: Replacing one-use packaging with reusable packaging could affect up to 20 percent of the total plastics market, the report estimates. Business-to-business packaging has the potential to increase reusable items such as pallets and crates.

Recycling:  Improving the global recycling rate, currently at 14 percent, has the potential to affect fully 50 percent of the plastics market. Doing so will require a number of comprehensive actions, including the initiation of a Global Plastics Protocol among developed nations to “reinforce recycling as an attractive, cost-competitive alternative.” Means to that end include choosing materials, pigments, and additives for maximum recyclability; improving collection and sorting of recyclable materials; and improving the technical capability of recycling facilities.

Food companies are in a unique position to initiate these strategies with regard to ingredients that they buy in bulk.

When they use flexible bulk containers, like bag-in-box or intermediate bulk containers, they can insist that the flexible carriers be designed, or redesigned, as monolayer. This gives them the advantage of using more easily recyclable materials while leaving the challenge of specifying those materials up to their suppliers.

As a business-to-business market, the food industry is especially well-positioned to execute reusability. Rigid reusable packaging for bulk shipments fits well into the closed-loop concept. The problem is that, with many liquid bulk ingredients, reusable bulk containers present issues of contamination. Even when this can be avoided, the energy used to clean and sanitize liquid bulk containers between shipments vitiates the ecological benefits of reuse. Using flexible containers inside rigid, reusable shells confers the best of both worlds: the closed-loop benefits of reuse with the sanitation of single-use food-contact materials.

As for recycling, the food industry can again reap the advantage of the business-to-business market. The biggest challenge in consumer recycling is segregating and sorting loads to ensure that each kind of polymer is processed separately. Because food companies have total control over the loads of used flexible bulk packaging they deliver to be recycled, load contamination is not an issue, and recyclers can process the loads  more efficiently.

“A new circular plastic paradigm will create great value for business and society,” says Andrew Aulisi, senior director, global environmental policy at Pepsico. “Many actions can be taken individually, but we need collaborative effort to make a meaningful shift.”

In summary, flexible bulk business-to-business packaging, such as CDF’s bag-in-box, Air-Assist products, and flexible intermediate bulk containers, has the potential to incorporate several of the strategies of the New Plastics Economy. They combine the safety and sanitation of one-time use together with the ecological soundness of reusability, and the recycling custody chain is tightly controlled.
