Materials Can Begin With What Already Exists
Agricultural residues and plant-based biomass form the starting point for OPUNÉ's material development.
Beyond a Single Feedstock
Cactus is a principal material origin within OPUNÉ®. It is not the only one.
OPUNÉ® works across a wider field of agricultural residues and plant-based resources, examining how underutilised biomass can enter new material applications. The feedstock changes. The material question remains the same: what can this resource become when developed for industrial use?
The Material Origins
These materials originate from different agricultural systems and possess different physical structures. Click any feedstock card to explore its dedicated material dossier.
Material composition varies by feedstock source, variety, growing conditions, processing history, analytical basis and test method; the profiles shown below are illustrative visual references only and are not OPUNÉ® product specifications or laboratory results.

Feedstock to Application Mapping
Feedstock characteristics can inform potential material pathways, with final suitability determined through processing, formulation and application-specific evaluation.
Fibrous Biomass
Cellulose-bearing feedstocks evaluated for flexible surface applications, textile composites, and non-woven substrates.
Structural Residues
Lignin-bearing materials evaluated for rigid applications, architectural components, and structural backings.
Mineral-Rich Biomass
Silica-bearing feedstocks investigated for filler, surface and application-specific performance pathways.
From Agricultural Residue to Material
04.01Agricultural production generates biomass beyond its primary commercial output. Some of these residual streams contain fibres, cellulose, lignin and other natural constituents relevant to material development.
The presence of a biological resource does not automatically make it suitable for a finished industrial material. Selection depends on the characteristics of the feedstock and the requirements of the intended application.
This is where material development begins: identifying what is available and determining what can be responsibly engineered from it.
Resource Use Is Only One Part of the Question
04.02The origin of a feedstock matters, but it does not describe the complete environmental profile of a finished material.
Processing, formulation, energy inputs, product construction, service life and end-of-life conditions can each affect the final outcome. OPUNÉ® separates feedstock origin from broader environmental claims rather than treating one as proof of the other.
A plant-based starting point is a material fact. Environmental performance requires its own evidence.
Different Origins, Different Material Possibilities
05.01A rice husk does not behave like coconut coir. Sugarcane bagasse is structurally different from banana pseudostem. Cactus presents another set of material characteristics.
This diversity is central to OPUNÉ®'s approach.
Rather than forcing different biological resources into a single material narrative, each feedstock can be evaluated according to its physical composition, processing requirements and potential application.
Designed Around Application
05.02Material development has to begin with where the material will be used.
Fashion products, furniture, accessories and mobility interiors each introduce different requirements for surface, construction and performance. Feedstock selection and material development therefore cannot be separated from the application being considered.
The objective is not to give every agricultural residue a second use. It is to identify material pathways where the resulting product has a defined purpose.
Evidence Before Environmental Language
Words such as sustainable, biodegradable, recyclable and low-impact describe distinct characteristics. They should not be used as interchangeable labels.
OPUNÉ® applies a narrower standard to material communication: state the material origin clearly and extend environmental claims only where the relevant evidence exists.
