One of these processes was the production of sugars from cellulose and lignin from trees, Jean Hamel, vice-president of industry at FPInnovations, tells Canadian Biomass (a sister publication of Pulp & Paper Canada ). (pulpandpapercanada.com)
One of the challenges of producing sugars is that you need to take the biomass and physically separate the wood component to give you access to the enzymes, so [they] can easily chew the cellulose and transform it into two types of sugars (C5 and C6 sugars), and then separate the sugars from the lignin," he explains. (pulpandpapercanada.com)
We came up with a technology that we call the TMP-Bio process, which makes use of refiners to break and open the fibres, react the enzyme with the cellulose and then separate the sugars and lignin components, providing two streams of bio-sourced chemicals," Hamel says. (pulpandpapercanada.com)
In this process, we are doing the inverse - we are dissolving the cellulose and the lignin remains intact. (pulpandpapercanada.com)
What's interesting is, if you look at how you make kraft pulp, what the kraft process does, it kind of dissolves the lignin around the cellulose, so the fibres remain intact," he continues. (pulpandpapercanada.com)

Lignin and capturing this wood-based extract is not new. (processwest.ca)
Mechanical or groundwood pulp is made by subjecting wood to an abrading action, either by pressing the wood against a revolving grinding stone or by passing chips through a mill. (britannica.com)
The debarked wood is next sent to grinders , where its moisture content is important for ease of grinding and quality of pulp. (britannica.com)
The pulp stock flows from the grinder pit to a series of rifflers and screens, which separate the heavy foreign material and pieces of unfibred wood (shives), knots, bark, and the like. (britannica.com)
Groundwood pulp does not have a high whiteness, being limited in this quality by the colour of the wood from which it is made. (britannica.com)
Lignin is a major component of wood and is one of the most abundant natural organic wood polymers which provides a multitude of functionalities. (sappi.com)
Lignin is one of the main building blocks of a tree and makes up 20-30% of the composition of wood. (papertoexport.com)

The aim of the project is to create a platform for research and use of the forestry raw material of lignin in order to extract more valuable products from forestry in the future, which would allow us to increase the value of forested land", says research leader Marie Gorwa-Grauslund. (lu.se)

This compound is an active kraft pulping agent. (armourvalve.com)

Early grinders employed round slabs of natural sandstone 69 centimetres (27 inches) wide and 137 centimetres (54 inches) in diameter , often directly connected to water wheels, to produce five or six tons of pulp per day. (britannica.com)
Today's much larger pulp grinders are usually powered by electric motors and automatically loaded. (britannica.com)
While it may seem obvious to some, it's a legitimate question and one which frequently comes to customer service here at a similarly styled Peugeot salt mill and Peugeot pepper mill (or pepper grinders) may look the same, there are important distinctions. (villaorchidee.be)

This means a unique opportunity to develop new products and solutions with lignin as raw material. (paperprovince.com)
Lignin is a non-toxic raw material with traceable origin and stable cost structure, and bio-based Lineo is ideal for companies looking for alternatives to oil-based products. (papertoexport.com)

Pulp mills are the most important lignin sources, in Sweden and globally, as they generate a large amount of lignin as a byproduct. (paperprovince.com)
