Bio based phenolic resins and adhesives derived from forestry residues wastes and lignin
(2012-11-10)
The work presented here aims to produce bio-phenolic compounds from forestry biomass (residues, wastes and lignin), and substitute petroleum-based phenol with the bio-phenolic compounds to produce high quality bio-based ...
Characterizing the microbial degradation of kraft lignin and lignin-derived compounds
(2014-12-12)
Analytical methods for characterizing the microbial degradation of Kraft lignin
and lignin-derived compounds were utilized with the goal of biologically generating
demethylated lignin for subsequent industrial applications. ...
Chemical and electrochemical modification of kraft lignin to value-added products
(2012-11-10)
Lignin is one of the most abundant biopolymers on earth, constituting approximately 30% of the dry weight of softwoods and 20% of hardwoods. It is a renewable, non-toxic, commercially available and low cost natural resource ...
Advanced ultrafiltration technology for lignocelluloses recovery and purification from thermomechanical pulp (TMP) mills process waters
(2017)
Process waters of thermomechanical pulp (TMP) mills contain a large valuable quantity of lignocellulosic materials that end up in the wastewater for biological treatment. In recent years, interest in utilizing such compounds ...
Lignin-based flocculant and dispersant for wastewater treatment
(2018)
The wastewaters produced from different industries contain fine and charged suspended particles and other impurities. Today, the removal of these colloidal particles from the wastewater has become a serious challenge for ...
New generation of dispersants by grafting lignin or xylan
(2017)
Synthetic dispersants are commonly used in the stabilization of various colloidal suspensions. However, their non-biodegradable and toxic natures hamper their industrial use. The use of natural polymers as dispersants for ...
Lignin Degradation by some wood-rot fungi with emphasis on cylindrocladium camelliae
(2012-11-10)
Thirty wood-rot fungi were screened for their ability to grow on media containing Kraft lignin with a limited amount of glucose. Of these fungi, twenty-three were tested for ligninolytic activity judged by decolorization ...
Lignin-based hydrogels
(2017)
Currently, limited information is available on lignin-based hydrogels, but its potential in commercial applications presents a promising avenue for the utilization of lignocellulosic materials. Recent studies have employed ...
Flocculation performance of lignin-acrylamide derivatives
(2019)
Wastewater produced in different industries contains fine suspended particles that raise a number of environmental concerns due to their potential toxicity and physicochemical properties and make their removal from industrial ...
Copolymerization of pretreated kraft lignin and acrylic acid to produce flocculants for suspension and solution systems
(2017)
The presence of dyes in the wastewater of textile industry poses a number of environmental
concerns due to their toxic nature and the removal of dyes from the wastewater is a major challenge
nowadays. Synthetic polymers ...
