Halophytes potential feedstock for cellulosic ethanol in Pakistan

SciDev. Halophytic perennial grasses that thrive in saline areas could serve as a viable source for ligno-cellulosic feedstock for cellulosic ethanol as well and help reclaim vast stretches of unproductive land in Pakistan, according to a new study published in the Journal of Biomass and Bioenergy.

... ethanol demands met from sources used for food may cause food shortage. This necessitates exploiting saline lands to produce non-food ligno-cellulosic biomass which, may be converted into ethanol without compromising human food production. Halophytes which produce plenty of biomass using saline resources (water and soil) may be an important alternative. This study shows that species like Halopyrum mucronatum, Desmostachya bipinnata, Phragmites karka, Typha domingensis and Panicum turgidum found in the coastal region of Pakistan, have potential as bio-ethanol crops. These perennial grasses are salt tolerant with high growth rates to produce ligno-cellulosic biomass of good quality (26–37% cellulose, 24–38% hemi-cellulose and <10% lignin) for ethanol production.

“These plants do not compete for good quality water and productive farmlands. They can be potentially used to produce large amounts of biomass while grown with brackish water on saline land, without competing with conventional agriculture,” Khan told SciDev.Net. “They could also help reduce carbon dioxide emissions by absorbing carbon dioxide to make food.”

With each occupier target costing $2700/day of paid-in social security funds from/for our "greatest generation", maybe some government personnel could instead plant and harvest 'Halophytic perennial grasses that thrive in saline areas' of the US.


They grow lots of cotton in Bakersfield, Ca. and other areas. When the cotton is picked there is a lot of plant material that does not need to go back to the land...lots of fuel there.


I can not see looking for plants that will grow in salt marshes when the U.S. has 500 million acres in production and LOTS of biomass already exists to make fuel.
