The sixth edition of the design biennale will revolve around the theme Useless, questioning the idea of use and the absence thereof, paving the way for new insights and interpretations on what we are producing and consuming, why and how. Occupying the heart of the Portuguese capital during 61 days, EXD'11/LISBOA invites rediscovery of the city’s centre and reactivates a series of overlooked urban spaces. Advocating a lower carbon footprint, the biennale promotes the creation of new, intriguing itineraries on foot.
