Overview
The dwindling reserves coupled with environmental concerns associated with the use of fossil hydrocarbons have led to the exploration of clean and renewable energy resources. Among the renewable energy resources, lignocellulosic biomass is the most abundant renewable bio-resource on earth. Lignocellulosic biomass is a complex biopolymer of cellulose, hemicellulose and lignin. Lignin accounts for 20 to 30% of the biomass and is the most abundant component after cellulose. The lignocellulosic-based bio-refineries that convert the biomass into liquid transportation fuels (thermochemical and biochemical), especially via biochemical platform, will generate significant amount of lignin. Thus, there is a pressing need to transform it to value-added products.
The higher carbon content and lower oxygen content of lignin, relative to the holocellulose fraction, makes it an attractive feedstock for the production of plethora of high-value bio-based products despite its complex structure. Lignin is a complex and water-insoluble aromatic polymer made of monomers such as coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol. The primary purpose of lignin depolymerization is to convert the complex lignin compound into small molecules, which can be used as fuels/basic chemicals for further application.
Several processes are being examined for efficient conversion of lignin to fungible fuels, additives, chemicals, building materials, etc. Some of them include catalytic pyrolysis, hydrotreatment, alkaline fragmentation/alkylation etc. Advances in analytical chemistry and computational modeling are required to understand the structure of lignin and devise engineering strategies to obtain desired products. Recent findings in biomass pretreatment technologies have led to efficient lignin recovery, which enabled to obtain products with desired chemical and physical attributes.
In view of the growing interest on bioresources, Bioresource Technology has planned to bring out one special issue on lignin utilization ranging from lignin separation/recovery, characterization, thermochemical and biochemical pathways for lignin valorisation, single step/multi step thermal and catalytic approaches for bulk/speciality/functional chemicals, and techno-economic analysis etc.
This special issue would fulfil the knowledge gap and lead to advancement of new knowledge on this very important subject of lignin valorisation. Some of the topics on lignin valorisation include:
- Understanding the complex lignin structure
- Pre-treatment techniques/recovery of lignin
- Characterization of lignin from various pretreatments
- Novel analytical methods for elucidation of lignin structure from biomass
- Production of high purity lignin
- Novel catalytic processes for valorisation of lignin
- Storage and stability of highly reactive industrial technical lignin for further utilization
- Novel and mild methods for production of high-value chemicals from lignin in biomass
- Novel and mild methods for production of diverse lignin-based products
- Novel and advanced catalytic materials for cleavage of recalcitrant bonds in lignin
- Biotechnological approaches for deconstruction and/or upgrading of lignin
