The Challenge
Conventional tree protection commonly relies on fossil-derived plastics, which can remain in the environment after their useful life and may require removal and disposal.
IP-led biodegradable composite
BOURA
A proprietary material platform engineered for products that need plastic-like performance, commercial manufacturability, and a responsible end-of-life.
Material Platform
A credible route away from persistent petroplastic.
BOURA is a proprietary biodegradable composite developed for real-world product substitution. It is intended for use cases where paper lacks performance, conventional plastic creates end-of-life risk, and brands need a material that can move beyond sustainability theatre.
The platform is being developed around soil and compost biodegradation pathways, including industrial and home composting conditions. Its current use in horticulture gives BOURA a live proving ground before broader sector rollout.
Commercial Thesis
Performance first. End-of-life built in.
Material Utility
Designed to deliver useful durability, mouldability, and formability in selected product formats.
Waste Reduction
Created to reduce reliance on persistent petroplastic in products that can be lost, littered, or difficult to recover.
Scale Potential
Structured as a platform for multiple categories rather than a single product line.
Validation Status
Clear claims. Clear status.
Investor-ready materials need disciplined language. BOURA is positioned around what is live, what is in progress, and what should be validated application by application.
Material ownership
Proprietary composite
Developed through four years of R&D and held as a distinct BOURA material platform.
Current use
Commercially applied
Already used in horticultural products, with further applications available for review.
Ingredient certification
TUV-certified core inputs
Core ingredients hold TUV certification.
Finished composite
Certification in progress
Finished BOURA composite certification is currently being progressed.

TreeBud
Biodegradable tree protection, engineered with BOURA™
TreeBud uses BOURA™ to create a biodegradable tree protection system designed to replace conventional plastic tree guards and their associated components.
The Material Brief
TreeBud needed a material suitable for an outdoor horticultural application: flexible rather than brittle, capable of being converted into a lightweight flat-packed product, durable enough for the tree-establishment period, and able to biodegrade rather than leave persistent conventional plastic behind.
The product architecture also needed to support a design that avoids separate plastic fixings, without publishing confidential formulation, supplier, or manufacturing data.
The BOURA Solution
By engineering BOURA™ around the requirements of the application, TreeBud was able to develop a lightweight, flexible protection system that ships flat and eliminates the need for a conventional plastic guard and separate plastic tie.
The final product is designed as a complete biodegradable protection system, rather than making only one component biodegradable while retaining persistent plastic components elsewhere.
The Result
Commercial-scale product application
Flexible outdoor protection
Flat-pack product architecture
No separate plastic tie
Designed for biodegradation after its useful life
Demonstrates suitability for horticultural applications
TreeBud demonstrates how BOURA™ can be engineered around a demanding real-world application. The same material-development approach can be applied across horticulture and other sectors where conventional plastics need a more considered end-of-life.
Develop with BOURAMarket Routes
Built for more than one sector.
BOURA starts where environmental exposure and end-of-life matter, then extends into short-life products where conventional material choices are under pressure.
Horticulture
Tree guards, plant protection, growing accessories, and soil-contact products.
Food Service
Straws, lids, stirrers, and serviceware where paper may not perform well enough.
Packaging
Formed inserts, rigid components, protective packaging, caps, and sleeves.
Partner Development
Custom product formats assessed through trials, tooling fit, and commercial need.
Engagement Pathway
A practical route from brief to launch.
Assess
Review product format, performance requirements, tooling, and end-of-life target.
Trial
Match BOURA to the application and define the validation work needed for confidence.
Commercialise
Move into licensing, manufacturing alignment, or strategic product development.
Licensing + Strategic Partners
