Overview
TWI has partnered with Zero Glue Bamboo (ZGB) on a groundbreaking series of trials to weld bamboo without adhesives or fasteners. This innovation promises to transform bamboo manufacturing by providing a faster, cleaner, and more sustainable bonding method—eliminating the need for toxic, fossil-fuel-based glues that currently dominate the industry.
What We Did
With support from Innovate UK EDGE, ZGB and TWI conducted a series of trials using a linear friction welder to bond bamboo strips. The work was led by TWI friction welding specialist Paul Clark and builds on TWI’s prior research into wood welding.
Key Results
- Bamboo strips were successfully joined in under two seconds
- Weld strength was found to be comparable to the strength of the bamboo itself
- Microscopic analysis confirmed a full bond across the entire interface, with no adhesives or mechanical fixings required

Why It Matters
Due to its tubular shape, bamboo must typically be split and glued into usable laminates—often with adhesives that are toxic, fossil-fuel-derived, and difficult to recycle. This innovation offers a radically different path, with major implications:
- No adhesives required
- Faster, energy-efficient production
- Lower manufacturing costs
- Simplified, circular end-of-life options (biodegradable, recyclable, or energy recovery)
Together, these advantages create a more competitive and genuinely sustainable alternative to conventional engineered bamboo and wood products.
What’s Next?
ZGB and TWI will now conduct further trials to scale the process—joining longer sections and welding higher stacks to unlock more applications. Mechanical and environmental testing is also planned, including moisture and temperature resilience. Early assessments suggest strong water resistance, adding further promise.
Applications and Opportunities
ZGB is exploring diverse uses for this technology—from consumer goods and automotive interiors to furniture and building materials. They are seeking partnerships with companies committed to sustainable materials innovation.
