Lignin Recovery
Lignin is an integral part of all lignocellulosic material. It serves as a structural component and plays a significant roll in the transfer of water in plants. Lignin is a biopolymer containing aromatic phenoxy-groups, aliphatic carboxy-groups and aliphatic alcohols, and if recovered and purified, lignin can be adapted to many functional chemistries.
Today, a significant amount of lignin can be found within a byproduct stream of pulp and paper mills known as black liquor. Black Liquor is a byproduct of the pulp and paper process that is generally concentrated in multi-effect evaporation and then burned for energy. GreenShift estimates that more than 50 million tons of lignin is burned each year at pulp and paper mills worldwide.
Furthermore, should the United States reach its lignocellulosic ethanol goal of 16 billion gallons per year, this industry would product a byproduct stream containing more than 100 million tons per year of lignin that most expect will also be burned for energy production.
GreenShift believes that if efficiently recovered and purified, lignin’s value would far exceed that of boiler fuels. As such, GreenShift has invested in and continues to invest in the development of cost effective extraction and purification process technologies that can be adopted by pulp and paper manufacturing facilities as well as lignocellulosic ethanol facilities.
Furthermore, GreenShift is investing in and developing high value applications for lignin. Many of the products being developed by GreenShift from lignin are direct replacements for petroleum derived products; thereby further reducing global dependence on oil, creating significant sources of income and improving the environment.

In addition to distillers corn oil, GreenShift has also begun marketing lignin from its patent pending recovery process from pulp and paper mills. GreenShift also plans to evaluate recovered lignin from future cellulosic ethanol facilities as well.
ReplyDeleteAny one concerned about about a noun used as a verb?
ReplyDelete"...this industry would product a byproduct stream ... "
about about what? say say again?
ReplyDeleteAnyone concerned that Somebody would split a word and also be too Dense to realize that the intended phrase is "produce a byproduct stream"?
ReplyDeleteCare and diligence are important attributes.
ReplyDeletetoo bad ur moma had niether LMAO
ReplyDeleteAnother down day. People can yell and scream at this truth all they want, but de-lisitng is becoming more likely each day.
ReplyDeleteToo bad repetitive bloggers can't be "de-listed", I know who I would vote out! Way too many posts describing hourly updates on a little "pump & dump" scam.
ReplyDeleteCare and diligence are important attributes.
ReplyDeleteWhat a waste to scream and yell over and over again you didn't do that 9 years ago.
Where is the fun, while we are "waiting"?
ReplyDeleteDown more than 7% today alone -- such fun! Pimping these new cadets; they need to be disciplined.
ReplyDeleteI just want to know about the case. Not about your mother nobody? Does anyone have any news?
ReplyDeleteWhere is the fun while we wait you ask.
ReplyDeleteConsidering your time spent on message boards, it's absolute clear you are having fun while waiting, kudos to you.
We the vast majority, have to get our fun out of our daily life with real people, pity us.
My money doesn't need a babysitter.
Down another 5%, the REGRESSION like the SHADOW, never lies.
ReplyDeletehear him scream and yell
ReplyDeleteDown another 3.5%, will that REGRESSION ever stop being right?
