Innovation in the Technology
-
The morphology of biomass can be altered by manipulating the bonding between cellulose and lignin at atmospheric pressure and enabling formation of biomass blocks from any biomass type.
-
The process is completely eco-friendly with optimum utilisation of the biomass and no waste is generated during the process.
Process
-
The process involves mixing solvent with biomass samples that leads to a homogeneous and highly viscous cellulose–lignin slurry.
-
The lignin is separated from cellulose by the solvent in the reactor and then repolymerized with cellulose on addition of antisolvent thereby altering the bonding between cellulose and lignin which gives unique morphology to biomass. The solvent is dissolved in added antisolvent and can be recycled.
-
Blocks can then be easily obtained by casting this cellulose–lignin slurry.
