Lignin structure, isolation, characterisation and modification for uses in value-added materials

Introduction to the field of lignin

Course content:

This course is a part of the Erasmus+ project entitled “Improving teaching competencies in the design of new generation biomaterials from wood waste” (BIOMAT). Project reference: 2024-1-PL01-KA220-HED-000246133 from the Erasmus+ programme:  KA220-HED – Cooperation partnerships in higher education. 

Welcome to the course on Lignin structure, isolation, characterisation and modification for uses in value-added materials!

This course provides an integrated overview of lignin from its biological origins to its utilisation in advanced material applications. Through a series of lectures, participants will learn about:

  • lignin biosynthesis and native structure,
  • major delignification processes and lignin isolation,
  • various types of technical lignins,
  • analytical methods for lignin quantification, molecular and thermal characterisation,
  • and strategies for fractionation, chemical modification, and polymer blending.

In addition to the lectures, participants will gain access to online learning materials developed within the Erasmus+ (BIOMAT) project, hosted on the UMCS (Lublin, Poland) e-learning platform: https://ekursy.umcs.pl/

These resources are available in English, Swedish, and additional languages, and include:

·      Video laboratories on:

·      PDF scripts providing detailed written descriptions accompanying the video-labs

·      A comprehensive Glossary, which functions as a handbook covering the core content of the course, together with additional explanations and references for further reading, including topics such as lignin-based polymeric spheres for water purification and composite preparation.

·      Students will also have the opportunity to perform self-assessment through an online pre-test and post-test. To access the interactive tests, students need to create a free account on the UMCS platform. The system will automatically score the results and provide feedback. Instructions for accessing the platform and the e-tests are provided together with the recorded lectures.

 

No laboratory participation is required at KTH; however, the video-lab modules on the UMCS platform provide a virtual hands-on learning experience.

The course is designed for PhD students, researchers, master’s/bachelor’s students, and industry professionals interested in lignin chemistry, processing, and applications in advanced materials.

Learning objectives:

After completion of the course, including the additional material provided at the UMCS e-learning platform, the course participant should have the knowledge and ability to:

  1. Explain the fundamental principles of lignin biosynthesis, native structure, and its role in plant cell walls, and demonstrate adequate knowledge of the major chemical features that influence lignin reactivity.
  2. Describe and compare the chemistry of the main pulping and delignification processes (kraft, sulfite, oxygen-based), and explain how these processes determine the structure and properties of the resulting technical lignins.
  3. Understand the classical analytical methods for determining lignin content in wood and pulp, and interpret the results in relation to pulping process efficiency.
  4. Explain the principles behind key characterisation techniques used for technical lignins, including molecular weight analysis (SEC), thermal analysis (TGA, DSC), and spectroscopic analysis, and reflect on how these data guide material applications.
  5. Suggest and critically evaluate strategies for lignin fractionation, chemical modification, blending, or composite preparation, based on the structure–property relationships relevant to polymer and materials applications.
