A breakthrough innovation transforms plastic waste into carbon-capturing material, offering a dual solution to two critical global issues.
Story Highlights
- Scientists transform PET plastic waste into a CO₂-absorbing material called BAETA.
- Innovation addresses plastic pollution and climate change simultaneously.
- BAETA operates efficiently at ambient temperatures, ideal for scaling up.
- The research is a significant step towards sustainable carbon capture solutions.
Turning Plastic Waste into a Climate Solution
Chemists at the University of Copenhagen have pioneered a method to convert polyethylene terephthalate (PET) plastic waste into a new material known as BAETA, capable of capturing carbon dioxide efficiently. This novel approach not only addresses the persistent issue of plastic pollution but also contributes significantly to climate change mitigation by reducing greenhouse gases. The breakthrough was publicly disclosed in September 2025, marking a promising step in sustainable environmental solutions.
This method represents the first successful demonstration of upcycling PET waste into a CO₂ sorbent with industrial potential. The process operates at room temperature, making it both energy-efficient and scalable. BAETA’s effectiveness rivals existing carbon capture technologies but with the added environmental benefit of reducing plastic waste. This dual-functionality underscores the innovation’s potential impact on global efforts to combat climate change.

The Context and Need for Innovation
Global production of PET exceeds 80 million tons annually, contributing to widespread environmental pollution, particularly as microplastics. Concurrently, rising CO₂ levels intensify climate change, necessitating scalable carbon capture solutions. Previous recycling efforts were hindered by contamination, leaving much waste unrecycled. The University of Copenhagen’s research offers a compelling solution by integrating waste management with climate action, positioning itself at the forefront of sustainable materials innovation.
Earlier carbon capture methods typically required high energy inputs and weren’t derived from waste materials. This new method not only circumvents these issues but also highlights the potential for chemical upcycling to address environmental challenges. The development of BAETA showcases how scientific advancements can drive the circular economy, transforming waste into a resource that aids climate mitigation.
Implications and Future Prospects
With successful laboratory validation, the focus now shifts to scaling up and commercializing the technology. The researchers are actively seeking investment and partnerships to facilitate industrial-scale production. The potential for pilot projects utilizing BAETA in industrial CO₂ capture demonstrates the technology’s immediate applicability. In the long term, widespread adoption could significantly reduce PET plastic pollution and contribute to global CO₂ reduction targets.
The innovation opens new economic opportunities for the plastic waste management sector and industries with notable CO₂ emissions. Furthermore, it may drive policy changes supporting integrated waste and climate solutions. The creation of new markets for materials derived from plastic waste could disrupt traditional recycling and carbon capture industries, accelerating the shift towards a circular economy.
