Lignin as the second most abundant biopolymer in nature serves as an important renewable source for sustainable production of higher value chemicals. Lignin can contribute to the mitigation of the crisis of fossil fuel depletion and climate change. Lignin waste-based resource recovery also contributes to the development of efficient waste management practices for better environment.
In response to the increasing research on lignin waste utilization, this special issue will cover the state-of-the-art of lignin biorefineries and lignin waste technologies and systems for resource (e.g., biofuels, materials and energy) recovery and their economic and environmental impacts on our society from local and global perspectives. Specifically, the special issue will cover the following sub-topics:
1. New technologies and principles of lignin waste-based chemical production
2. Advanced system models and designs for sustainable lignin waste management
3. Techno-economic (e.g., cost-benefit analysis) and environmental sustainability (life-cycle assessment) of lignin waste
4. Large-scale supply chain analysis of lignin waste to resource production
5. Novel utilization and valorization of valuable resources such as biochar derived from lignin waste
