lignin in production with
many end uses
https://purelignin.com/home/ - pilot plant up and running

In
sulfite pulping, lignin is removed from wood pulp as
sulfonates. These
lignosulfonates have several uses:
[11]
Dispersants in high performance
cement applications,
water treatment formulations and textile
dyes
Additives in specialty
oil field applications and
agricultural chemicals
Raw materials for several chemicals, such as
vanillin,
DMSO,
ethanol,
xylitol sugar, and
humic acid
Environmentally sustainable dust suppression agent for roads
The first investigations into commercial use of lignin were reported by
Marathon Corporation in
Rothschild,
Wisconsin (
USA), starting in 1927. The first class of products that showed promise were
leather tanning agents. The lignin chemical business of Marathon was operated for many years as Marathon Chemicals. It is now known as LignoTech USA, Inc., and is owned by the
Norwegian company
Borregaard, itself a subsidiary of the Norwegian conglomerate Orkla AS.
Lignin removed via the
kraft process (sulfate pulping) is usually burned for its fuel value, providing energy to run the mill and its associated processes.
More recently, lignin extracted from shrubby willow has been successfully used to produce expanded polyurethane foam.

In 1998, a
German company,
Tecnaro, developed a process for turning lignin into a substance, called
Arboform, which behaves identically to
plastic for
injection molding. Therefore, it can be used in place of plastic for several applications. When the item is discarded, it can be burned just like wood.

Lignin is already proven to have several uses with companies already established .I hope the tests we re waiting to hear from are ligit.
