How do two of the new generation's most passionate designers, Nienke Hoogvliet (1989) and Dave Hakkens (1988), use design to tackle the world's biggest problems?

Nienke’s mission is to make the world’s second most polluting industry – the clothing industry – more sustainable. She is currently working on sustainable applications of seaweed, such as using it to make paint.

Dave’s ambition is equally ambitious. His Kamp project attempts to establish a living and working community that uses a minimal carbon footprint. He is building this community in Portugal, where he has bought nine hectares of land. He has created a blueprint for a new society and made it open source so that anyone can adopt and improve it, and the system can be used worldwide.

Where many people might see problems, Nienke and Dave envisage solutions. But how realistic are their ambitions?
