At TrimTabs, sustainability and circularity are not just buzzwords; they are fundamental principles that play a huge role in shaping everything we do, driving our commitment to developing materials and processes that align with a circular economy. However, there has long been an open question about the true recyclability of carbon nanotube (CNT) end products. Recently, a study was published that put an end to this debate. In the study, published in Carbon, researchers at Rice University demonstrated that CNTs can be readily recycled without compromising their performance.

Fully Recyclable CNT Fibres

The research outlines how CNT fibres can be fully and easily recycled, regardless of their original composition. By combining continuous segments of single-source virgin CNT fibres – made from different CNTs – and reprocessing them into a mixed-source CNT fibre, the scientists achieved recycled CNTs with no loss of properties. 

The recycled CNT fibres displayed identical morphology, structure, alignment, and properties to virgin fibres made from directly mixing raw CNTs. This achievement demonstrates that the recycling process is not only feasible but also efficient, ensuring the integrity of the material is preserved. 

This discovery is particularly exciting given the recent advancements in CNT synthesis and manufacturing processes. The ability to recycle CNTs effectively positions them as a promising alternative material for a broad range of applications. From energy storage solutions like batteries to everyday items such as electric blankets, the potential of CNTs to replace traditional, less sustainable materials is now amplified by their recyclability. This innovation directly contributes to reducing waste and promoting a more circular approach to material use, aligning with global sustainability goals.

TrimTabs’ Take

At TrimTabs, we prioritise not just the functionality and performance of our CNT products but also their entire lifecycle, including end-of-life considerations for both CNT products and the plastics we use as feedstocks. The findings from this study, which demonstrated the recyclability of CNTs, come as music to our ears and affirm our belief in the potential of CNTs as a key material driving us towards a sustainable future.
