01
Lignin-rich biomass
Lignin surrounds and binds cellulose fibers in the plant cell wall.
Technology
Opening the lignin network
Nanozyme catalysis makes cellulose-rich fiber more accessible, with a magnetic catalyst that can be recovered and reused.
Enzyme-like activityNanomaterials.
Nanomaterials.
Biological inspiration.
Nanozymes are nanomaterials with intrinsic enzyme-like activity. Our catalysts have laccase-like and peroxidase-like activity that oxidatively attacks the lignin network of plant cell walls.
The treatment removes up to 50% of the lignin in lignocellulosic biomass, opening the fiber for downstream processing.
How it worksLignin removal,
Lignin removal,
step by step
A treatment stage between feedstock preparation and your downstream fiber or energy process.
02
Nanozyme catalysis
Laccase-like and peroxidase-like activity acts on the lignin network.
03
Accessible fiber
Up to 50% lignin removal creates a cellulose-rich fiber stream.
Conceptual mechanism illustrations. After treatment, a magnetic field separates the nanozyme from the slurry for recovery and reuse.
Fiber performance6.2 km
6.2 km
breaking length
Straw-fiber handsheets produced in the laboratory demonstrate a breaking length of 6.2 km.
We work with partners to evaluate the fiber against their own product specifications and production conditions.
Process characteristics
Designed for biomass processing
Magnetic recovery
The nanozyme separates from the slurry in a magnetic field and can be reused across batches.
Easy-to-treat black liquor
Our black liquor is easy to treat and environmentally friendly. Liquor treatment is considered as part of the integrated process.
No strong acid or alkali
The core nanozyme route uses enzyme-like catalysis without sulfur chemistry or strong-alkali cooking of the biomass.
Flexible local feedstocks
Straw, bamboo and wood residues can be evaluated as additional fiber sources near your mill.
Process integration
Two routes into your mill
Choose a standalone nanozyme delignification route or a pretreatment stage ahead of an existing chemical line.
Nanozyme delignification
Use nanozyme treatment as the delignification stage in your biomass-to-fiber process.
- Prepare local biomassStraw, bamboo or wood residues
- Nanozyme delignificationUp to 50% lignin removal and magnetic catalyst recovery
- Separate fiber and liquorCellulose-rich pulp and an easy-to-treat black liquor stream
- Feed your production lineMolded fiber, papermaking or bioenergy
Pretreatment before pulping
Add a treatment stage upstream of chemical delignification to reduce the lignin load.
- Prepare existing feedstockBiomass as received at your plant
- Nanozyme pretreatmentRemove a portion of lignin before chemical processing
- Tune chemical delignificationEvaluate chemical demand and operating conditions
- Continue downstreamYour existing fiber processing and conversion equipment
| Process aspect | Conventional chemical pulping | NanoZymBio core route |
|---|---|---|
| Chemistry | Strong alkali or sulfur-based cooking, depending on the process | Enzyme-like catalysis without strong-alkali cooking |
| Black liquor | Liquor handling and recovery depend on mill configuration | Environmentally friendly black liquor that is easy to treat |
| Catalyst recovery | Cooking chemicals recovered through the mill’s chemical cycle | Nanozyme catalyst recovered magnetically and reused |
| Feedstock | Selected for the mill’s established pulping process | Process development for locally available biomass |
