“At Karibou, results drive progress. In 2021, we became one of the first paper cup maker to earn flustix certification. In 2025, we set a new global benchmark with one of the lowest polymer thresholds ever measured. Our cups are home compostable, recyclable and free from intentionally added PFAS — no excuses, no shortcuts. With a capacity of 1.5 billion cups a year produced in Barcelona, and further expanding every year, we pair advanced paperboard innovation with full-scale precision and traceability. We’re proud to be flustix certified.”

“The collaboration with flustix was very well-organised and solution-oriented. With a clear system and expert guidance, flustix ensured that we were able to implement the certification process in a clean and transparent way. In particular, the technical support and pragmatic approach convinced us.”

“What we value most about flustix is the focus on credibility and integrity, which strengthens the impact of our message and reassures our customers of the validity of our claims. Having the flustix RECYCLED certification adds significant value to CIRCULAR EDGE by providing proof of quality, compliance, and sustainability. It helps differentiate our product in a competitive market where transparency and certified sustainability are increasingly demanded.”

“flustix certification confirms EraCup Natural as a benchmark board for food service applications, designed to deliver outstanding converting performance and respond effectively to new market demands. It reflects our ongoing commitment to developing safe, regulation-compliant, and highly recyclable solutions that enable converters and brand owners to advance their sustainability goals and strengthen brand differentiation.”

“Transparency and trust — this is what our partnership with flustix delivers. The professional guidance throughout the certification process was first-class. The flustix trustmark confirms the high share of 45% post-industrial recyclate in our dry vacuum series (T-Range). For us, it is an effective way to make a tangible contribution to our sustainability goals: the reduction of 1.9 kg of virgin plastic per product. The flustix certificate is therefore a central pillar of our sustainability strategy.”

“Our customers welcome the guidance that independent certifications provide when making purchasing decisions. They should feel fully informed and be able to choose our recyclates based on verifiable data. We are proud of the quality of our products – and, of course, also of the fact that they passed the flustix certification process smoothly and quickly.”
