It might come as a surprise to learn that the pet food industry is a significant contributor to the global waste stream, accounting for 3% of all flexible packaging (about 300 million pounds annually). Currently, 99% of the 300 million pounds of plastic waste produced by the pet food industry each year wind up in landfills. Put another way, pet food packaging is adding 297 million pounds of plastic waste to our landfills each year.

When trying to reduce a number from 99%, it might seem like a pretty easy task. However, there are a few key challenges that make transitioning to sustainable packaging in pet food a more complicated endeavor than it might seem.

I recently had the pleasure of hosting Kara Stoney, Value Chain Coordinator and Sustainable Packaging Manager at Dow, on Petworking. Kara and I discussed the efforts that the pet food industry is taking to move to sustainable packaging, and the barriers that must be overcome to successfully complete the journey.

Listen to the episode to hear Kara and I discuss:

• The challenges associated engineering packaging that is both recyclable and durable enough to protect product quality through the supply chain. It doesn't matter if packaging is recyclable if using it results is large amounts of wasted food products.

• The importance of maintaining palatability when transitioning to recyclable packaging materials, especially for pet food products. Some recycled plastics can impart odors to the food, and pets, particularly dogs, are much more sensitive to changes in smell and taste than humans are. If a switch to more sustainable packaging results in a pet detecting a change and refusing to eat the food, it could lead to the pet owner switching brands.

• The Pet Sustainability Coalition's Packaging Pledge, and the likelihood that companies will be able to meet the goals that 100% of their packaging will be recyclable, reusable, or compostable, and at least 30% of their packaging will be made from recycled content by 2025.

• The How2Recycle labeling system, and its impact on increasing consumer recycling, and decreasing the amount of wish-cycling (putting non-recyclable items in the recycling bin in the hope that they will be recycled).

• Dow's sustainable innovation in both mechanical and advanced "chemical" recycling technologies. Advanced recycling breaks plastics down to their original monomers, yielding recycled content that mirrors virgin resin - a game-changer for pet food.

• Dow's Pack Studios, a facility where brand owners and packaging converters can test sustainable solutions prior to production, reducing the risk of costly trials on their own production lines. Line time is so valuable that brands are hesitant to run trials, so Pack Studios reduces that barrier.

My discussion with Kara highlighted the complexities in improving packaging sustainability, but also provided an optimistic look at the industry's progress through strategic partnerships, innovation in recycling technologies, and the power of consumer advocacy to drive meaningful change. Younger Millennials and Gen Z consumers are increasingly demanding sustainable options, which puts pressure on brands to continue to seek out new and innovative sustainable packaging solutions.

Ultimately, advancing sustainable packaging requires an industry-wide effort. Stakeholders across the value chain - from resin producers, to converters, brands, and consumers - must collaborate closely. Continued investment in recycling infrastructure and technologies is also paramount.
