Unilever has increased investment in packaging research and development aimed at reducing virgin plastic usage. At its Global Packaging R&D Centre, significant resources are being dedicated to advancing sustainable packaging materials and technologies. The initiative is part of Unilever’s commitment to combat plastic pollution through reduction, recycling, and collaboration.

The company has more than doubled its investment in materials science and technology in recent years, bolstering its in-house expertise to meet ambitious plastic reduction targets. Pablo Costa, global head of packaging at Unilever, emphasizes the need for continuous improvement, saying, “Our progress in reducing plastic waste sets industry standards, but we must remain proactive.” Unilever is intensifying its focus on materials science to optimize internal capabilities while partnering with external stakeholders to bring sustainable solutions to market.

Central to its strategy is increasing the incorporation of post-consumer recycled (PCR) content in packaging. Unilever’s Packaging R&D team has developed digital tools that predict packaging colors using data from the characterization of 160 grades of recycled plastics. This innovation reduces development time by approximately 25%, minimizing reliance on physical prototypes.

Furthermore, Unilever is pioneering next-generation flexible materials under their ‘Future Flexibles’ program, aiming for 100% recyclable or compostable flexible plastic packaging by 2035. Its research includes developing materials for pouches and sachets that align with recycling systems and biodegradability standards, addressing technical challenges such as barrier protection and product sealing without conventional plastic films.

Pablo Costa highlights the complexity of these advancements, particularly in packaging liquid products. He says, “Technical challenges persist, especially for items like laundry detergent and shampoo.” Unilever is evaluating over 3,000 emerging technologies, exploring adaptations from sectors like pharmaceuticals and electronics to innovate their packaging solutions.

Unilever acknowledges that achieving its sustainability goals requires broader industry transformation and systemic change. The company advocates for comprehensive policy measures that support sustainable practices across the plastic life-cycle. Costa says, “Collaboration is essential to scaling alternative materials and models. We are committed to leading this transformation and preparing our supply chain and consumers for a sustainable future.”
