Leaf-derived fibrous components
Produced from processed leaf biomass. Contribute to paper blends, visual character, alternative input logic and technical development routes.
Core technology
From fallen leaves to papermaking fibers and material components.
Releaf technology converts dry leaf biomass into fiber-like fractions, semi-fibers, fillers and formulations for paper, packaging and future material applications.
Core technology: leaf-to-material conversion
Paper is one output. The core is a conversion system.
Leaves are not standard pulpwood. They arrive as seasonal, heterogeneous biomass with botanical structure, mineral contamination, moisture variability and species-level differences. Releaf's technology is built around that reality: intake criteria, stabilization, preparation, fractionation, formulation and controlled integration into paper routes. The result is not leaf powder added for decoration. It is a material system designed to preserve useful structure, manage variability and create outputs that can be tested, specified and converted.
Conversion process · five steps
-
01
Leaf stream
Fallen leaves are generated by cities every year and can be collected through municipal and partner systems with defined intake criteria.
-
02
Stabilization
The seasonal stream is prepared and stored so that autumn biomass can become a more reliable year-round resource.
-
03
Preparation
Leaves are cleaned, sorted and prepared to reduce incompatible materials such as sand, stones, plastics and excess moisture.
-
04
Fractionation
Prepared biomass is converted into fibers, semi-fibers, fillers and formulation routes for papermaking and further material work.
-
05
Integration
Leaf-derived components are integrated into paper grades and product applications according to performance, visual and commercial requirements.
Recipes, chemical details and confidential parameters are not shown publicly.
Inside the process
How a fallen leaf becomes fibre.
Fiber and fraction system
Intermediate fraction
Between longer fibrous behavior and fine filler. Supports controlled distribution of leaf-derived matter in the paper web and R&D formulations.
Fine processed leaf fraction
Used inside material blends. Can influence tone, texture, visible pattern and material identity while supporting formulation logic.
Refined fibrous pulp route
A more refined fibrous pulp route under approved IP wording. Used when the application requires more fiber-like contribution and deeper processing.
Application-specific recipes
Combine leaf components and compatible fibers. Adapt material to kraft, testliner, white/brown paper, specialty and R&D routes.
Proof-first
Claims follow evidence.
A new material has to earn trust. Releaf communicates through samples, datasheets, tests, converter feedback, use cases, batch documentation and validated certifications where available. If a claim is not validated, it must be framed as development work, not as a finished guarantee.
Sample kit → Datasheet → Technical test → Converter trial → Use case → Certification / LCA where applicable
