Starbucks, ConAgra Foods talk packaging sustainability initiatives, challenges at TAPPI 2012

Seattle, WA - As TAPPI attendees sipped on white coffee cups with a green siren logo, Brent Denniston, Starbucks VP of global procurement, said the company is fully aware of the profound effect of its packaging.

"Our packaging is an asset, but it's also a liability," Denniston told TAPPI members and attendees. "What is iconic to our company is our cup, people associate their experiences with the brand through it. But they also associate it with not being environmentally responsible."

"Packaging waste is the number one environmental issue to many consumers," he said.

At the TAPPI PLACE (May 6-9; Grand Hyatt Seattle) Conference, Denniston and Gail Tavill, vp of sustainable development for ConAgra Foods, both spoke about packaging for their brands. The topic of packaging sustainability and recycling were prevalent in both speeches.

Starbucks paper coffee cups, partially made from recycled content, are constructed with a polymer-based liner to prevent hot liquid from leaking.

Dennison highlighted several initiatives the company has undertook to produce a greener cup such as rolling out plastic cups for its cold beverages that are produced with polypropylene cups and lids, and launching new lightweight plastic cups to reduce resin consumption.

While Starbucks is interested in composting, he said the company's first preference is recycling.

However, Denniston said one major challenge of recycling is recovering.

As of now, once the cups leave the stores, it's up to the consumer to recycle the product, but recycling success depends on the availability of commercial recycling services where the company's stores are located, he said.

In an attempt to provide a solution to the recycling issue, Starbucks has launched in-store recycling programs at select stores. While the program has hit some hiccups along the way, Denniston said the company is committed to eventually offering in-store recycling on a wide scale.

In addition, Starbucks has a goal of making 100% of its cups reusable or recyclable by 2015.

"It's a challenge, creating a dynamic where the consumer will bring in a reusable cup, that we have to figure out how to leverage," Denniston said.

He hinted there maybe a product to address this initiative hitting stores in the next coming months.  

Beyond cups

Starbucks is also looking into reducing packaging from its whole bean and ground coffee products, and various other packaging products.  

"We have a focus on leveraging packaging technology to improve freshness and product shelf life," he said. "I'm sure there is technology out there we haven't explored to help reduce waste and have a longer shelf life."

With regards to its packaged coffee product, Denniston said Starbucks isn't satisfied with the packaging.

"When you see our packaged coffee product, it doesn't set itself apart from the competition, in terms of shopability," he said. "We have a big focus on innovation in flexible packaging."

ConAgra Foods' green efforts

Gail Tavill with ConAgra Foods said sustainability isn't just about what's right for the environment, there's also a business case for it.

"Companies that follow more sustainable practices have more sustainable economics," she said.

Since packaging arguably has a reputation as wasteful, Tavill said it's important to remind people about the value of packaging.

"If a package breaks, causes food to spoil - then we fail," she said. "Packaging needs to be part of the solution, not the problem. Our goal is to embrace the value of packaging and strive to make it as efficient as possible."

She pointed out various packaging examples the company implemented for a more efficient and sustainable use of materials.

ConAgra Foods was the first company in North America to incorporate post-industrial recycled polylactic acid into shrink film packaging materials. By collaborating with its suppliers, the company converted 260,000 pounds of resin from non-renewable resources (PVC and PET g) to PLA. The company's PLA shrink film contains more than 50% post-industrial recycled material, and it uses this material for tamper-evident seals on some of ConAgra Foods' table spreads.

"We know there are challenges with PLA and how it can impact the bottle-to-bottle recycling strategy," she said. "But we have strict restrictions on PLA and we make sure it doesn't stay with the package because we don't want potential contamination."

The company also uses recycled PET in some of its frozen food trays. ConAgra uses several sizes of the trays for Healthy Choice, Banquet, Kid Cuisine, and Marie Callender's brands. Nearly all are pigmented black. DuPont_ConAgra.jpg

Still, rPET and virgin PET have somewhat different functional properties and chemistry, which created several challenges in blending, extruding, and thermoforming the trays so they would meet both the company's and FDA standards.

However, once those hurdles were tested and cleared, the trays were ready for the public.

"We do use rejected rPET for some of the microwave dishes," she said. "Because the dishes are eventually colored we don't care about the clarity."

Tavill said sustainability is complicated process from all perspectives.

"You can't have radar vision, one decision has consequence to others," she said. "We have to make sure what we put out can be recovered for recycling."
