Carbon nanotubes (CNTs) are increasingly being used in electronics products. CNTs have unique chemical and nanotoxicological properties, which are potentially dangerous to public health and the environment. This report presents the most recent findings of CNTs’ toxicity and discusses aspects related to incineration, recycling and potential remediation strategies including chemical and biological remediation possibilities. Our analysis shows that recycling CNTs may be challenging given their physiochemical properties and that available strategies such as power-gasification methods, biological degradation and chemical degradation may need to be combined with pre-handling routines for hazardous materials. The discussion provides the background knowledge for legislative measures concerning specialized waste handling and recycling procedures/facilities for electronics products containing CNTs.
