TU Delft explores the circular use of glass focusing on the Reuse, Reduce, Recycle pillars of circularity.
In terms of Reuse, a novel high-strength, yet reversible, joining technology is developed based on lead-free solder. This technology is particularly suitable for multi-material components that incorporate brittle materials such as engineered ceramics or glass.
To Reduce the material use, structural topology optimization is implemented in a series of monolithic structural glass components ensuring a design with maximum stiffness and minimum volume. All samples are cast on different types of disposable mould technologies pushing the boundaries of fabrication possibilities. Taking the concept of reduction a step further, knitted basalt fibre moulds are used for slumping flat glass into doubly curved shapes. This innovative type of moulds minimizes the mould material needed compared to a traditional slumping technique.
Finally regarding Recycle, previously discarded glass waste streams, such as medical vials, automotive glass, PV panels and electronic waste, are mapped and utilised at the TU Delft glass lab for the development of innovative kiln cast glass panels with possible application in façade cladding, interior separation and other applications in the built environment. Focus of this research is creative integration of contaminants in the glass, unlocking a new pathways for recycling currently rejected waste streams.
