A startup from Oak Ridge National Laboratory has developed a process that transforms discarded glass bottles into construction materials. Vitriform3D uses binder jet 3D printing to create tiles and architectural cladding. The result is an artificial stone composed of up to 95% recycled glass, merging sustainability with additive manufacturing.
The technical process behind printing with recycled glass 🛠️
The method crushes glass bottles into a fine powder, which a robotic arm spreads in layers while injecting adhesive and ink. This simultaneously binds and colors the material. The piece is heated in a kiln to set its shape, a process similar to ceramic firing. The final product contains 90-95% recycled glass and 5-10% adhesive polymer, offering a solid alternative to natural stone.
From bottle to tile, bypassing the recycling bin ♻️
Now your Sunday beer bottle can end up as bathroom cladding. Quite a social climb for glass, going from being stepped on at the beach to decorating designer walls. The best part is, if you don't like the color, you can always blame the adhesive. Recycled glass has never had such a solid resume.
