The International Lignin Institute (ILI) is an international professional association, created in 1991, with headquarters in Lausanne, Switzerland.

ILI is primarily functioning as a networking organization, supporting its members and the cause of lignin. ILI is guided by the vision of a future technology for a multi-product conversion of alternative lignocellulosic plants in environmentally proper cyclic processes where lignin is a major product, used at highest possible value.

ILI attempts to complement existing wood chemistry and chemistry institutions and promote modern R&D management concepts in terms of teamwork, partnerships and interactive, focused communications.

Among its many activities for the promotion of lignin, ILI organises events that allow the lignin stakeholders to meet and prepares documentation and Internet data for bringing together the dispersed information on lignin in one point (for example with the Thematic Online Newsletter and with its collection of analytical protocols).

These activities are conceived in a way to address as much the interests of industry (existing and potential lignin producers, existing and potential lignin users) as of the scientific communities in Research and Development.

A particular emphasis is given to prepare data allowing New Researchers to quickly and efficiently learn about the main issues in the lignin field which would otherwise be very difficult and time consuming. Summary documents are available on production (industrial lignin isolation, fractionation, chemical modification), analytical issues and applications. Recent developments are continuously documented on the Thematic Online Newsletter and on other password protected internet pages available exclusively for members
