Green Graphene: Cleans Water Differently

Green Graphene: Cleans Water Differently
Clean water is becoming scarcer, and treating it is becoming harder. The EU Urban Wastewater Treatment Directive requires full, complex water treatment across member states by 2045. The problem is that current technologies cannot deliver it.

Vision

František Zelenák believes graphene – the material everyone knows from pencil lead – can be part of the answer. The goal is to take this material from the laboratory into industry and produce it at a scale that makes a real difference.

Gamechanger

At Masaryk University's plasma nanotechnology centre CEPLANT, graphene membranes are produced from graphene paper. The paper is processed using patented plasma technologies, resulting in membranes that can filter a wide range of pollutants – with efficiency comparable to reverse osmosis, but at 100 times higher flow rate. Significantly faster.

Who is it for?

For industry where advanced materials science could find application – in water treatment or beyond. And for investors or partners looking for a project with proven technology and a clear market context.

What has worked so far?

The technology has been verified in laboratory conditions, the plasma processes are patented and industrially tested. František is completing his doctorate this year and is ready to move the project into a startup.
František is looking for an industrial partner for further development, startup collaboration, or a setting for prototype roll-to-roll production. If you work in manufacturing or know someone who might be interested, get in touch.
