Contract Manufacturing, Powder Technologies and Prototyping
Specialist in process solutions, toll manufacturing and spray drying services for lignin and other biopolymers from lab to ton scale.
Quality and precision for highest demands
Lignopure’s team has over a decade of experience in the processing of lignin and related biopolymers to ultra-fine powders and tailored ingredients at highest quality at various scales.
We have a proven track record of implementing and scaling up material- and application-specific processing routes – with every step being tailored and carried out in close collaboration with our customers. Compliance with the customer’s specifications is strictly controlled in every manufacturing step.
We always aim for the best powder quality at highest process efficiency, from crude feed pretreatment, to drying, microparticle formation, post-treatment and packaging. For this, we not only make use of our own equipment, but can rely on a professional network of contractors to ensure the optimal processing route. We are also open to explore new, tailored technologies and manufacturing pathways.

Benefits of Spray Drying
- Mild processing for sensitive materials
- High-quality powders with good flowability
- Customizable particle size and moisture content
- Optional integration of more complex formulations or reactions
- Minimal downstream processing
- Maximal scalability
Optimal raw material preparation before drying is decisive for end-product quality. We offer supplemental pre- and post-treatment services tailored specifically for biopolymer spray drying — ensuring consistency, performance, and process efficiency from the start.
The word lignum is Latin for wood — but lignin has long stood in the shadow of cellulose, undervalued despite being essential to plant structure, strength, and resilience. That changes now.
