Biodiesel From Grass, Wood Chips

A
Japanese government-affiliated research institute has developed
technology for creating a diesel fuel from materials such as grass
cuttings and wood chips, The Nikkei reported in its Tuesday morning
edition.


 


Although similar technology exists for bioethanol fuel for gasoline cars, this is said to be a world first for diesel vehicles.



 


The
Research Institute of Innovative Technology for the Earth is aiming for
commercial production in three years. RITE was established in 1990 by
the government and leading Japanese firms in such industries as
automobiles and power.



 


The
biodiesel fuel in question uses a type of alcohol known as butanol made
using genetically modified microorganisms. The biobutanol was created
by cultivating a large number of these microbes in a vat and adding
sugar produced by breaking down such plant fibers as grass and tree
cuttings, wood and rice straw.



Light
oil is generally used in diesel fuel. But in testing commissioned by
RITE, Honda Motor Co. (7267.TO) subsidiary Honda R&D Co. confirmed
negligible effects on vehicle performance when biobutanol was mixed
with light oil.



 


RITE
sees the biofuel as key to cutting greenhouse gases emitted from diesel
vehicles. Once mass production begins, the fuel is seen costing almost
the same to produce as bioethanol for gasoline-powered cars.



 


Demand
for biofuels made from plants is expected to grow because they help
curb carbon dioxide emissions. But to date, biodiesel fuels have been
made from materials like coconut and tempura oils. There has thus been
fierce competition among RITE, BP Plc (BP) of the U.K., DuPont Co. (DD)
of the U.S., and others to create a biodiesel fuel from plants. RITE
has already applied for an international patent on the technology.

My dream to eradicate malnutrition of world thru algae..

Every 5 second, one child under the age of 5 dies because of hunger and malnutrition!!!!!!

India
has 198 million undernourished people. china 150 million and rest all
countries in world, less than 50 million, Pakistan 43miliion.


UNICEF survey 2009 on malnutrition says, India 42%, pakistan 5%, bangladesh 5%, nigeria 5% etc..
Prime minister Manmohan singh called it a NATIONAL SHAME in 2009 independence day speech......(Ref: Frontline april 2010)

Eradication of this malnutrition (by 2015) is UN's millennium development goal no 1. India's 11th 5yr plan(2007-2012) has this malnutrition and anemia reduction in woman as the prime plan....

SO WAT CAN U DO TO AVOID THIS?

IF
THERE IS SOME FOOD, which if u eat 1gram, gives u protiens,
vitamins,minerals etc equal to eating "1kg if fruits and vegetables"
put together. Cost, not more than 2-4rs per day where u'll
be getting all ur daily requirements of essential vitamins, minerals,
protiens etc etc just for the cost of a coffee or cigar........ ( that
much of fruits and vegetables costs more than 100Rs)


  • Thats SPIRULINA
this food is recommended and approved by UN,WHO,FDA,FAO,INDIAN GOVERNMENT etc etc NASA aoustronauts carry it to space, bcz of high nutrition and lowest weight........ No
side effects, people in western countries and africa have been uing it
from more than 500 years....... pregnant and feeding woman, children,
ppl of all age are fed with this.......... so totally safe and reliable........... This small plant has 200x more protien than beef,4 times more than soy, 25times more vitaminA than carrot, 3times
more GLA than olive, 50times more iron than Spinach, lots of
antioxidants, enzymes, and list goes endless.................................and..........and..............and...........SUPER FOOD.

This
alone is used to treat HIV patients(world's best immune booster), it's
anti-diabetic, anti hyperlipedimc, ANTI AGING, anti cancerous(works
against more than 100 cancers),wound healing, helps in weight loss,
zero cholesterol, reduces already having cholesterol,antui fungal,anti
bacterial, antiviral etc etc....... properties and uses endless....... Can be used for weight loss, with no side effrcts and this is completly natural and vegetarian product..... So question? why are ppl not using it???????!!!!!!!!!!!!!!!!!!!! millons
of people are using through out the world and south asia's largest
producer is near mysore, who export it many european
countries............Hundreds of, billion dollar companies r there on
this.......... This is a algae,which u can grow it in ur home with out any technology aid.......... This grows using CO2 , liberating Oxygen........ so eofriendly... If
all Indians eat it and become stronger, no illness, well built, more
working hours, increasing nations income, india becoming super
power............... dreams...... Can be eaten
simply like that or with milk, or mix with chapathi, curry, sambar,
samosa, health drink, baby food, chocolate, ice cream....... Can
be used to feed animals,fish culture, poultry, pig's, excellent
agricultural fertilizer, food for soldiers in border............... CFTRI (Central food technological research institute )mysore, India has been working on this from more than 30 years and new products like milk shakes, chocolates,cosmetics,etc based on this r coming to market now a days.............. UN, FDA,WHO calls it as a SUPERFOOD, world's best and future food........

WHO : "For WHO, Spirulina
represents an interesting food for multiple reasons, rich in iron and
protein, and is able to be administered to children without any risk.
We at WHO consider it a very suitable food."
- United Nations World Health Organization (WHO), Geneva, Switzerland June 8Th, 1993

What The UN Says About Spirulina:

? "There is a need for both national governments and inter-governmental organizations to re-evaluate the potential of Spirulina to fulfill both their own food security needs as well as a tool for their overseas development emergency response efforts" - The UN-Food and Agriculture Organisation (FAO) Report on Spirulina 2008

(Ref : please visit the site www.iimsam.org)

IIMSAM is an organisation under UN, UNESCO and completly based on spirulina.
Barak Obama's uncle and granny are working with this and many more celebrities..

So..... Using this dam cheap product(cost wise), we can work wonder's( if we get donations or raise funds, we can distribute it to people at free of cost)...... If u like to eradicate malnutrition from india, world, etc ............... come , join hands, join brains for a cause...
So, why can't we eradicate the problem of malnutrition using this?

Using something finally IDEAL in this world.. AN IDEAL FOOD,food PRODUCT, medicine ETC......

If
you would like to contribute for this cause in any possible way, either
by following or promoting or giving funds, everything will lead for a
better INDIA....


I have started an NGO, where we supply free spirulina for poor and needy...

A request with all oilgae members is to help by donations or giving us spirulina or giving the contacts of some donors or donar organisations for charity...

for any doubts,query's etc , just message me on phone( 91 8904456566) or mail me rmaheshv@gmail.com.

Direct conversion of wet algae to biodiesel


Researchers at the University of Michigan have published the
feasibility of a two-step hydrolysis-solvolysis process to produce
biodiesel directly from wet algal biomass, eliminating the need for
costly biomass drying, organic solvent extraction and catalysts. The
paper on the process was published in the ACS journal Energy & Fuels.



In the first step, wet algal biomass contained 80 percent moisture
and was reacted with subcritical water to hydrolyze intracellular
lipids, conglomerate cells into an easily filterable solid that
retained the lipids and produced a sterile, nutrient-rich aqueous
phase. In the second step, the wet, fatty acid-rich solids underwent
supercritical transesterification with ethanol to produce fatty acid
ethyl esters (FAEEs). The team used Chlorella vulgaris algae, which
contained 53.3 percent lipid content.



According to Phillip Savage, lead researcher on the project, the
team gathered the wet algae grown from the lab and centrifuged it to
transform the algal biomass into a paste-like substance. ?At large
scale that probably wouldn?t be applicable for an economical process,?
he noted. ?We got something that was probably around 10 to 20 percent
solids to the balance of water.?



The research yielded promising results, Savage added, but the
project is anticipated to be refined and optimized in order for to
demonstrate greater economic and environmental feasibility of the
process on a larger scale.



?More remains to be understood regarding how whole cells,
hydrothermally processed algal biomass and intracellular constituents
influence supercritical transesterification and potentially contribute
to nonester components in the final fuel product,? the paper reported.
?Additional research and process optimization are likely to improve
yields and reduce process inputs (e.g. ethanol), thereby minimizing the
overall environmental impact of algal biodiesel production. To be
economically viable, biodiesel yields must be above 95 percent and
preferably higher than current norms achieved with alkali-catalyzed
processes.?

Is burning algal biomass as coal substitute, ok?!!!

Because algal biomass has quite a good amount of protein and other compounds... Burning this may lead to Nitrogen based oxides which may lead to atmospheric pollution...

Like this,what are the possibilities or risks of getting other contaminants in air?

But how much is that compared to normal coal?

Whats the economics compared to coal?

It's just that was in the back of my mind from few days...

Please share your thoughts on this...

NOx credits and algae's role in absorbing it !!!!!!

I want to know about the NOx credits and the different ways in which we can feed algae on this(Ex: by dissolving it in water etc....). Because all of us talk about crubing CO2 and carbon credits, but NOx credits is also important in coming days i guess... So, please comment on this and lets all start thinking about this as well...

How efficient are diatoms in producing biodiesel?

As diatoms are known to secrete the oil content after death, is that helpfull in avoiding the oil extraction step?

How is the yield?

Is that economical?
