Defibrillated Lignocellulose Recovery Guided by Plant Chemistry and Anatomy – A Pioneering Study with Lupinus angustifolius

Advanced Sustainable Systems, Volume 8, Issue 7, July 2024.
Lupin is identified as a promising lignocellulose source. It serves as a model organism for legume crops, providing sustainable solutions for biomass utilization and alternative protein sources. Optotracing, a novel technique, offers non‐disruptive lignocellulose analytics, guiding a design‐driven biomass fractionation.

Bleach boosting and direct brightening by multiple xylanase treatments during peroxide bleaching of kraft pulps [PDF]

, 1996
The effects of multiple xylanase treatments were assessed during the peroxide bleaching of three pulps: Douglas-fir (kraft); Western hemlock (oxygen delignified kraft); and trembling Aspen (kraft).

Preventing Strength Loss of Unbleached Kraft Pulp [PDF]

, 2003
Kraft pulp fibers lose inter-fiber bonding ability when they are dried during the manufacture of paper. Adverse environmental consequences of this loss include (a) limitations on the number of times that kraft fibers can be recycled, (b) reduced paper ...

PRODUCTION OF DISSOLVING GRADE PULP FROM ALFA

BioResources, 2010
Alfa, also known as Stipa tenacissimaI or “halfa”, is grown in North Africa and south Spain. Due to its short fiber length, paper made from alfa pulp retains bulk and takes block letters well.
