- Graphene is a new nanomaterial with many promising applications, including in composite materials, transparent displays, electronic components and biosensors. We have conducted a number of life cycle assessment (LCA) studies of emerging production routes for this material. The studies cover the three production routes that currently have the most patents and largest scientific interest: Exfoliation, chemical vapour deposition (CVD), and epitaxial growth on silicon carbide. From these studies, a number of results have been obtained, which provide environmental guidance towards less impacting graphene production at an early stage in technology development. Results for exfoliation show that although some processes (chemical and thermal reduction) are energy-intensive (in the order of 1000 MJ/kg), others (ultrasonication) have life cycle energy requirements below those of today’s energy-intensive materials (
