Latitude is partner of the “International Workshop on Waste Architecture. Rehabilitation of landfills” that will be held at S. Margherita di Pula (Cagliari, Italy) between the 6th and 7th of October 2015. The workshop is a parallel event of the international conference SARDINIA 2015 / 15th International Waste Management and Landfill Symposium (Forte Village Resort, 5-9 October 2015). Waste Architecture is a new and relatively unexplored conceptual and design topic which promises to give rise to a lively debate between environmental professionals, and architecture and urban design experts. The workshop represents the first of a series of thematic seminars on environmental design and interventions related to the collection, disposal and management of waste. This first appointment will focus mainly on the architectural, functional and landscape rehabilitation of old landfills. The event is coordinated by ARCOPLAN / Studio associato di ingegneria e architettura with the scientific support of the Department of Architecture, Design and Planning / University of Sassari / Alghero and the Department of Industrial Engineering / University of Padova.
