What We're Building with Biomaterials
Why We Exist
What Comes Next
Why We Exist
Steel is carbon-heavy. We’re replacing it with a new class of bio-based components that store carbon, meet safety standards, and install with zero learning curve.
How We Build
What Comes Next
Why We Exist
We blend industrial hemp with a clean thermoplastic resin to form strong, consistent shapes. Each BioStud is formed using a proprietary method designed for structural and fire performance.

What Comes Next
BioStud is our first commercial product but not our last. We're building a portfolio of biomaterials to replace steel in facades, partitions and joists. All engineered to meet spec, save carbon, and install the same way.
The Science Behind BioStuds
Life Cycle Assessments by Imperial Consultants and BRE
Two independent LCAs confirm BioStuds dramatically reduce embodied carbon—and are designed for a circular economy.
✅ 71.5% Less Embodied Carbon than steel studs with potential for up to 95% reduction at scale.
✅ Lighter to Transport, Easier to Install - lower emissions on site and in transit.
✅ Fully Recyclable - low-waste production and a closed-loop future.
Proven Fire Performance – independently tested by BRE
BioStuds have undergone full‑scale fire testing by BRE Group, the UK’s leading independent testing authority. Tests were carried out in complete wall systems to validate real‑world performance - not lab theory.
Fire Resistance Testing (EN 1364-1:2015)
✅ 60-Minute Fire Resistance – single-layer British Gypsum Gyproc Fireline plasterboard.
✅ 120-Minute Fire Resistance – double-layer British Gypsum Gyproc Fireline plasterboard.
✅ No Flaming or Gas Venting – Maintained integrity throughout testing.
What BRE Tested
Fire performance was assessed under controlled conditions, measuring:
- Integrity – preventing flames and hot gases passing through
- Insulation – limiting heat transfer to the non‑fire side
- Stability – maintaining structural performance during fire exposure
All tests were conducted as full partition wall assemblies, ensuring performance reflects real building conditions.

Proven Structural Load Performance – Tested by BRE in Full-S
To validate real-world performance, BRE conducted full-wall structural tests simulating partition pressure, deflection, and load conditions.
✅ Supports Walls up to 4.6m High with double-layer standard wallboards, 600mm stud spacing – suitable for commercial and residential partitions.
✅ Tested in Real Assemblies – Not just the stud - BRE tested full partition systems for accurate validation.

Proven Acoustic Performance – Tested by BRE in Full Wall Sy
BioStuds help reduce airborne noise transmission—crucial for comfort in homes, offices, healthcare, and education spaces.
✅ Up to 55 dB Rw Sound Reduction - Basic setup: 40 dB Rw → Enhanced system: 55 dB Rw.
✅ Real-World Acoustic Validation - BRE-tested in complete partition systems, not lab mock-ups.
✅ Outperforms Steel Framing - Composite structure absorbs and dampens sound better than metal.
