Lasting Value
Since the very beginning of Fairphone, we’ve been committed to addressing the phone’s full lifespan, from use and reuse to recycling.
As a social smartphone developer, we’re building a stable, high-performance phone that lets you get the most out of your device – now and for years to come. But no mobile phone lasts forever, so we’re immediately tackling the end of its life as well. For every Fairphone sold, €3 goes to Closing the Loop, a foundation that sets up projects in countries where safe e-waste recycling is not yet facilitated.
Our ultimate aim is to make new phones entirely from recycled materials. At the moment, we’re exploring the possibility of sharing responsibility with manufacturers for recycling of their products through lease contracts. In addition, we’re building partnerships with companies that collect used phones
