Biograf – patented technology
We provide technology that enables the production of graphite and other carbon products from bio-based and recycled feedstocks to meet industrial requirements. Biograf Oy’s patented technology, developed through long-term R&D, enables the manufacture of commercially and industrially viable carbon products from bio-based raw materials instead of fossil feedstocks. Our solution offers alternative, low-emission carbon materials particularly for the metal and battery industries.
The method is based on high-temperature thermal treatment and enables the rapid and energy-efficient production of graphite with high process efficiency compared to existing methods.
Key features and benefits:
- Fast production: Graphite is produced in a fraction of the time required by conventional methods.
- High efficiency: The process achieves high energy efficiency compared to current graphitization methods.
- High purity: The end product is directly suitable for high-value downstream processing without heavy post-treatment steps.
- Excellent degree of graphitization: The produced graphite matches the properties of 2H synthetic graphite.
- Bio-based and local feedstocks: Enables low CO₂ emissions and secure, regional raw material supply chains.
- Fully dry process: Does not generate acids, wastewater, or other problematic side streams.
- Industrial integrability: The process is designed to integrate into existing industrial production environments, ensuring competitive and scalable production.
Together, these factors make bio-based carbon materials, for the first time, a truly industrially competitive alternative to fossil-based carbon products.
With Biograf Oy’s technology, lignin can be converted cost-effectively into valuable carbon products, ranging from biochar to the highest-grade synthetic graphite.

Biochar
In the metal industry, as a substitute for fossil carbon used as a reducing agent.
Syngas and bio-oil
For clean energy production or further processing into biofuel / other bioproducts.
Pure lignin – the key to the next stage of bio-based carbon materialen
Lignin is one of the largest renewable carbon reserves on Earth—yet it has long been underutilized. In recent years, interest in the extraction and upgrading of lignin has increased significantly, as it has come to be recognized as a valuable feedstock for bio-based carbon materials, chemicals, and advanced material applications, including biochar and biographite materials.
