Lignin oxidation technology for versatile lignin dispersants

Lignin oxidation technology for versatile lignin dispersants
The aim of LigniOx project is to demonstrate the techno-economic viability of the unique alkali-O2 oxidation technology (LigniOx) for the conversion of several lignin-rich side-streams into versatile dispersants, and especially high-performance concrete and mortar plasticizers.
Lignin is a key by-product of lignocellulosic biorefineries, and a valuable renewable resource for Europe’s bio-based industries. Annually, approximately 60 million tons of lignin is extracted from wood as a by-product of the pulping industry. Even more is expected to originate from second generation bioethanol production in the future.
To fully exploit these raw material streams, there is an urgent need to commercialise economically and sustainably viable lignin upgrading process technologies such as the LigniOx technology outlined in this project.
