LigniOx™ lignin recovery
ANDRITZ LigniOx lignin recovery: Transforming lignin into high-performance dispersants for diverse industrial applications.
ANDRITZ LigniOx is an innovative alkali-O2 oxidation process that transforms lignin into high-performance dispersants. This cutting-edge technology utilizes O2 gas to enhance the anionic charge of lignin, producing a versatile oxidized lignin product. LigniOx dispersants are ideal for use as concrete plasticizers and in various other applications, offering superior performance compared to traditional lignosulfonate products and even competing with synthetic superplasticizers.
Versatile applications for LigniOx
LigniOx dispersants have demonstrated exceptional performance across a wide range of applications:
- Concrete Plasticizers: Enhance the workability and strength of fresh and matured concrete.
- Paints and Coatings: Efficiently disperse inorganic pigments for high-quality finishes.
- Gypsum Plasticizers: Improve the properties of gypsum-based products.
- Anti-Scaling Agents: Prevent scale formation in water treatment processes.
- Flotation Aids: Act as depressants in mining flotation processes.
- Agricultural Products: Serve as dispersants for pesticides, complexing agents for nutrients, and soil conditioners.
Environmental and economic benefits
The LigniOx technology not only delivers high-quality dispersants but also offers significant environmental and economic advantages:
- Reduced Production Costs: No excess sulfur in chemical circulation compared to ‘traditional’ lignin recovery.
- Environmental Sustainability: Increased biodegradability and reduced impact on climate change compared to fossil-based alternatives.
- Efficient Chemical Recovery: Recovery of valuable chemicals (Na, S) and possibility for production of BioMeOH as a co-product.
Market potential
Metsä Group, in collaboration with ANDRITZ, is set to construct a demonstration plant for LigniOx in Äänekoski, Finland. ANDRITZ will serve as the technology provider for this plant. The primary goal of the demo plant is to showcase the LigniOx process. This initiative is a joint effort between Metsä, ANDRITZ, and DOW industries to introduce new lignin-based materials to the market. The Äänekoski bioproduct mill will highlight the technology's potential, demonstrating its capability to replace fossil-based chemicals in concrete production.
Future prospects and business opportunities
ANDRITZ is committed to advancing the LigniOx technology for commercial-scale applications. By partnering with industry leaders and leveraging insights from the demo plant, ANDRITZ aims to enable the market entry of LigniOx concrete plasticizers and create new business opportunities for biorefineries, technology providers, and the chemical industry.
ANDRITZ is working also together with VTT Technical Research Center of Finland for testing and development of LigniOx process for interested Pulp&Paper Customers.
