Lignins Isolated via Catalyst-Free Organosolv Pulping from Miscanthus x giganteus, M. sinensis, M. robustus and M. nagara: A Comparative Study [PDF]

Molecules, 2021
As a low-input crop, Miscanthus offers numerous advantages that, in addition to agricultural applications, permits its exploitation for energy, fuel, and material production. Depending on the Miscanthus genotype, season, and harvest time as well as plant

Ecofriendly Organosolv Process for Pulping of Tender Coconut Fibre

CORD, 2015
The huge biomass generated by vendors of tender coconut is the broken husks refuse dumped along roads and highways in Kerala. These dumps become breeding grounds for diseased causing germs and carrier mosquitoes causing threat to human life.

Study on the Structure of Lignin Isolated from Wood Under Acidic Conditions [PDF]

Molecules
Lignin obtained in acidic conditions is a waste product in various technological processes like sulfite pulping, organosolv pulping, or bioethanol production. Knowing the structure of the lignin enables its use in high-value-added applications.

Removal of wood extractives as pulp (pre-)treatment: a technological review

SN Applied Sciences, 2021
Wood extractives usually do not exceed five percent of dry wood mass but can be a serious issue for pulping as well as for the pulp itself. They cause contamination and damages to process equipment and negatively influence pulp quality.

Progress in Organosolv and Steam Explosion Pretreatments of Oil Palm Fibers for Biomacromolecules Extraction

Journal of Natural Fibers, 2022
Plant fibers are excellent sources of biomacromolecules, but the extraction of these chemicals critically depends on pretreatments on the biomass. In this work, steam explosion followed by acetosolv or ethanosolv pulping were evaluated as pretreatments ...

Effect of replacing polyol by organosolv and kraft lignin on the property and structure of rigid polyurethane foam

Biotechnology for Biofuels, 2013
Background Lignin is one of the three major components in plant cell walls, and it can be isolated (dissolved) from the cell wall in pretreatment or chemical pulping.

Organosolv Fractionation of Softwood Biomass for Biofuel and Biorefinery Applications

Energies, 2017
Softwoods represent a significant fraction of the available lignocellulosic biomass for conversion into a variety of bio-based products. Its inherent recalcitrance, however, makes its successful utilization an ongoing challenge.
