(413e) Upgrading Lignin Side-Streams into Sustainable Ligniox
LigniOx oxidation technology converts various industrial lignin raw materials to high-performing plasticizers and versatile dispersant. In addition to kraft lignin, it was shown that LigniOx solutions based on organosolv and hydrolysis lignin have high dispersing performance in cementitious material.
LigniOx lignins A new type of high performance concrete plasticizer
LigniOx oxidation technology converts various industrial lignin raw materials to high-performing plasticizers and versatile dispersant. It was shown that kraft lignin based LigniOx solutions have high dispersing performance in cementitious material similar to polycarboxylate based concrete superplasticizers. We could demonstrate that this class of
LigniOx lignins: High performance concrete plasticizers and versatile
Abstract A simple and economic alkali-O2 oxidation (LigniOx) process has been developed for the production of concrete plasticizers and versatile dispersants from technical lignins.

- Which companies are developing lignin products for concrete and gypsum applications?
- Metsä Group and ANDRITZ will focus on developing the production process of the new lignin product and its integration into the bioproduct mill, as well as making the product properties suitable for various end uses. Based on the lignin product, Dow will develop high-performance bio-plasticisers for concrete and gypsum applications.
- Can oxidised lignin replace fossil-based plasticisers in concrete production?
- As a result, a new demo plant is now under construction VTT coordinated an EU-funded project called EU-LigniOx during 2017–2022 that brought together several partners, including ANDRITZ, Metsä Fibre and Dow to demonstrate the viability of oxidised lignin as a replacement for fossil-based plasticisers in concrete production.
- What is the ligniox process?
- “We have further studied and developed the LigniOx process – which involves oxidising the lignin and processing it with membrane technology. The tests have been carried out at our Bioruukki pilot centre in Espoo and at the separation technology unit in Jyväskylä.
- Can ligniox be used in biorefineries?
- ANDRITZ is pleased to add LigniOx to their business portfolio and sees great potential in offering the process to biorefineries worldwide, working together with VTT in supporting the industrialisation of the process. “By combining our experience, technology and top expertise, we’re able to develop new products for our customers and the market.
- What is lignin used for?
- Lignin is a side stream of pulp production separated from the wood fibres into black liquor and currently mainly burned as bioenergy. However, it has potential as a versatile raw material for various chemical and material applications, and the industry is searching for ways to utilise it more efficiently in high-value products.
- What is the EU-ligniox project?
- “The EU-LigniOx project is an excellent example of how R&D projects can bring together companies in the value chain and initiate further collaboration in advancing – in this case – totally new technology and products.
