Recycling yogurt pots has become a significant challenge. As millions of these plastic containers are discarded, it raises important questions about their recyclability and what can be done to mitigate the environmental impact.
The Unsolvable Puzzle of Recycling Yogurt Pots
In France alone, an astonishing 15 billion yogurt pots are consumed annually. Yet, what happens to these containers once they’re empty? For years, many have assumed that after being tossed in the recycling bin, they would be properly processed and reused. However, it’s not that simple. The main issue lies in the materials used to make these pots, particularly polystyrene, a material that is difficult to recycle and causes significant environmental damage.
According to Citeo, a company that manages packaging waste, polystyrene pots used in yogurt and dairy desserts are typically sent to a plant in Valencia, Spain, where they are broken down and recycled. However, experts like Henri Bourgeois-Costa, from the Tara Ocean Foundation, argue that this process is largely ineffective. Polystyrene tends to break into tiny fragments when processed, which are nearly impossible to repurpose. The end result? Only 5 to 10 percent of the material is reused in products like flower pots or disposable hangers, while the rest is either incinerated or dumped in landfills.
The Environmental Impact of Polystyrene
Polystyrene is notorious for its environmental harm. Not only is it one of the top pollutants found on beaches and in the ocean, but it’s also incredibly light and breaks into tiny particles that spread easily, making it difficult to clean up. This problem is compounded by the material’s toxicity. Studies have shown that polystyrene can be harmful to microalgae, disrupting marine ecosystems. According to the Surfrider Foundation, these tiny plastic fragments can travel long distances, harming wildlife and contaminating natural habitats.
Yet, despite these significant challenges, yogurt makers continue to use polystyrene for packaging, a material classified as a probable carcinogen by the World Health Organization. The persistence of this practice is puzzling, especially given that alternatives exist. For example, Danone now uses PET (polyethylene terephthalate), the same plastic found in water bottles, for their yogurt containers. PET is far less problematic—it’s easier to recycle and is less toxic. Furthermore, PET can be reused in food packaging, making it a more sustainable option compared to polystyrene.

Is Chemical Recycling the Future?
With the mounting pressure on companies to find better solutions, some industry players have turned to chemical recycling as a potential fix. This process breaks down plastics into their base components, allowing them to be reused in products like new yogurt pots. Sophie Génier, a recycling expert at Citeo, explains that since 2020, the company has been working on a chemical recycling plant in Belgium. This technology, which uses pyrolysis to recycle polystyrene, is still in its early stages, with only 8,000 tons of material expected to be processed annually. But it’s still far from the 60,000 tons of yogurt pots consumed annually in France. Even with this new method, the challenge remains: will it be enough to solve the issue of yogurt pot waste?
Despite efforts to improve recycling, the recycling rate for yogurt pots in France is still dismally low. Only about 5,000 tons of these pots are collected for recycling each year, and much of the effort is focused on increasing the volume of materials that can be processed. There are campaigns urging consumers to dispose of yogurt pots in the recycling bin, even if they are unsealed or dirty. However, these containers’ lightweight nature makes them difficult to collect effectively.
The Dilemma of Polystyrene’s Future
The real dilemma arises from a regulatory back-and-forth. Despite efforts to ban non-recyclable polystyrene packaging starting in January 2025, industry pushback has resulted in a reversal. The French government has granted companies permission to continue using non-recyclable polystyrene, citing the need to meet ambitious recycling targets set by the European Union. While chemical recycling offers a potential solution, its environmental cost, such as toxic emissions from the facilities, remains a concern.
Environmental advocates are skeptical. Henri Bourgeois-Costa notes that even in the U.S., where chemical recycling has been in practice for years, it’s received plenty of criticism due to the pollution and low efficiency of the process. As organizations like Beyond Plastic have pointed out, the costs involved in building and operating such plants are enormous, and even when they function at full capacity, they handle a mere 1.2% of U.S. plastic waste.
What Needs to Change?
The ongoing recycling crisis of yogurt pots underscores the need for innovation in packaging design and waste management. While chemical recycling could be a step forward, its environmental risks and low efficiency are significant roadblocks. The industry needs to shift its focus to sustainable alternatives and invest in the infrastructure needed to reduce waste at the source.
Ultimately, consumers, manufacturers, and governments must collaborate to find viable solutions that don’t just look good on paper but also work in practice. If companies like Danone can successfully make the switch to PET, others should follow suit, leading the way toward more eco-friendly packaging. Only through concerted effort and technological advancements can we hope to see significant progress in reducing the environmental impact of yogurt pots and similar packaging materials.
The world’s reliance on polystyrene and other non-recyclable materials is a pressing issue that cannot be ignored. It’s time to rethink how we approach packaging and waste disposal to create a cleaner, more sustainable future for all.
