Materials 2050: Reuse and Recycle

Arquitectura en Corto invites you to the screening of the short film Les Matérialistes, which will take place on Wednesday, January 29, at 7:00 PM at the Arquia Foundation (c/Tutor, 16, Madrid). What construction materials will be used in 2050? Directors Jonathan Lapalme and Meggan Collins define Les Matérialistes as a docufiction film that blends current data with future projections to invite a collective reflection on the model shift required to transition toward a circular economy and carbon neutrality. Following the screening, the event will feature Alicia Carvajal, an architect from Dark Matter Labs—one of the organizations that supported the short film and the Les Matérialistes project—along with Lucas Muñoz, a designer recognized for his reuse of materials in his projects, and Albert Sagrera, an architect and environmental consultant specializing in the environmental impact of materials and construction waste management.

The European Straw Building Gathering (ESBG 2025) will take place from September 18 to 21, 2025, in Canet de Mar (Barcelona). This international event will bring together professionals, collectives, and those interested in bio-construction and sustainability.

Waste or resources?
Arquitectura en Corto invites you to the screening of Gypsum Concrete, taking place on Wednesday, September 24, at 7:00 PM at Espacio Arquia in Madrid (C/ Tutor, 16). Directed by Simon Pénochet, the short film documents the research conducted by the French architecture firm Ciguë to transform demolition waste from a construction site on the outskirts of Paris into material for a new building being constructed on the same plot. The project proposes manufacturing concrete for floor slabs using recycled aggregates and gypsum as a binder—a material recyclable through urban mining processes that is available in large quantities throughout the Paris region. The film explains how testing validates the material for this application and concludes that using gypsum instead of cement reduces CO2 emissions by up to four times. In Spain, several projects have already been completed where materials found in situ were repurposed as resources for new construction. Following the screening, Héctor Fernández Elorza (hfe arquitectos) and Josep Ricart (HARQUITECTES) will discuss the topic and present examples of their small- and large-scale interventions—ranging from single-family homes to urban public spaces—where material reuse has been a core project strategy.
