Resource efficient renovation using a 3D printable material from underutilized biomass
Research Project, 2022 – 2024

In this project, we address an acute sustainability issue of the prevalent use of fossil-based, energy-wasteful materials in renovation. The aim is to establish a more resource- and energy-efficient alternative, composed from underutilized biomass upcycled from industry side stream products, comprising microorganisms and cellulose. The new material is 3D printable and can act as an impregnating coating applied onto aged building elements to protect them from further degradation and to restore their aesthetic value, eliminating premature replacement and prolonging their life span. It can also be 3D printed as lightweight second-skin panels, to modernize existing facades and interiors with a fully biodegradable, circular and energy-efficient alternative to fossil-based solutions. Via an exceptional knowledge crossover between architectural design, biotechnology and materials science, the project will derive a new material, 3D printing method and physical demonstrators showing practical uses in architectonic elements.
