Mercedes-Benz Returns to Screws, Replacing Glue for Enhanced Sustainability and Repairability

Under its Tomorrow XX program, German automaker Mercedes-Benz is rethinking fastening technology by switching from glue to screw assemblies, significantly boosting vehicle sustainability and repair convenience. This addresses material waste reduction, easier part disassembly, and owners' demands for repair-friendly designs.
The first application targets headlight lenses: shifting from glued attachments to screw fixation allows damaged lenses to be replaced individually by unscrewing a few bolts, avoiding full headlamp disposal. This cuts resource use and enables easy self-repairs. For decades, adhesives were favored for lighter weight, lower fuel use, and CO2 reduction, but they complicate repairs—leading to whole assemblies landfilled—and hinder material separation for recycling.
Mercedes is also testing thermoplastic rivets for soft door panels instead of ultrasonic welding, allowing simple drilling for disassembly in repairs or end-of-life recycling. Engineers stress this screw revival balances innovation, environmental duty, and user ease. Future models will feature these solutions, upholding the century-old brand's commitment to progress and responsibility.
