Lignin valorization (materials & fuel)
Converting lignin from pulp and paper into chemicals, materials and fuels inside a biorefinery — commercial-scale LignoBoost plants since 2013 and 2015, replacing fossil phenol and fuel.
1 · What it gives
Lignin valorization converts lignin into chemicals, materials and fuels inside an integrated biorefinery. Lignin-based products can replace fossil feedstocks such as phenol in phenolic resins, or fossil fuel in lime kilns. Commercial scale exists: the Domtar LignoBoost plant (25,000 tonnes a year, since 2013) and Stora Enso’s Sunila plant (50,000 tonnes a year, since 2015). Global lignin production is estimated at 40–50 million tonnes a year, mostly from pulp and paper.

| D2 | Biodiesel, renewable diesel (HVO) and SAF instead of fossil diesel and heating oil Replaces: Fossil diesel in transport and generators; gas-oil heating; jet fuel (via SAF blends); also disciplines waste cooking oil and tallow that … | FUEL |
| D3 | Biogas and biomethane from organic waste instead of firewood, charcoal, LPG and diesel Replaces: Firewood, charcoal and dung as cooking fuel (household air pollution); fossil LPG and natural gas for cooking and heat; diesel-generator … | FUEL |
| D3 | Bioethanol as fuel and octane/oxygenate instead of MTBE, high-aromatic petrol and fossil petrol Replaces: MTBE and ETBE oxygenates (groundwater pollutant), aromatics (benzene, toluene) used for octane, lead anti-knock legacy; part of fossil … | FUEL |
| D1 | Pulp bleaching with xylanase enzyme pre-bleaching and ECF/TCF processes (oxygen, peroxide, ozone) — instead of elemental chlorine bleaching; with biological effluent treatment Replaces: Elemental chlorine (Cl2) and hypochlorite bleaching of kraft/sulfite pulp; reduces chlorine dioxide demand in ECF | CHEM |
| D1 | Bio-based and soil-biodegradable plastics instead of fossil commodity plastics (PET, LDPE, PS) and their microplastics Replaces: Fossil polyethylene/polypropylene/PS/PET in flexible and rigid packaging; intentional microplastics (restricted in the EU since 2023); … | PACK |
| D1 | Bio-based binders and bio-solvents instead of petrochemical resins and VOC solvent systems in paints and coatings Replaces: Petro-derived alkyd/acrylic binders; volatile organic solvent systems (white spirit, toluene, xylene) in solvent-borne paints; part of … | CHEM |
3 · How to implement 4 steps
- 1Acidify with CO2Absorb CO2 to acidify the black liquor (LignoBoost step 1).
- 2FilterSeparate solids by filtration.
- 3Re-suspend and acidifyRe-suspend the lignin and acidify with sulphuric acid.
- 4Wash and useWash and filter to purified lignin, then supply it as a binder, resin component or fuel.

5 · Rules & route to market
declaration of conformity (testing extra)
Information, not legal advice — confirm the procedure for your product. (2026-10-06)
United States
The sources reviewed on 2026-10-16 identified no the US regulator or standard specific to this technology. Treat the route as case-by-case and ask for a check.
European Union
The sources give one product-level standard: lignin-phenol-formaldehyde resins used in plywood meet Bonding Class 3 of EN 314-2. No other EU rule is named for lignin itself.
China
The sources reviewed on 2026-10-16 identified no China regulator or standard specific to this technology. Treat the route as case-by-case and ask for a check.
