The SmartCity Expo World Congress is a key event for the smart city sector and a meeting point for public and private entities. For the 2015 edition, the Barcelona City Council wanted to clearly display its stance regarding sustainability and urban ecology. Anthesis Lavola produced and designed a stand for the City Council following sustainability and energy efficiency criteria to minimize its environmental impact. We used natural wood, reusable plastics and native plants in biodegradable pots as materials for the stand.
