What plants might be grown, just for bio-fuel?

[Michaelangelica]

Candlenut Tree

I wonder if anyone has looked at these plants for biofuel.
I first saw it on Maj. gittins "ABC Bush Tucker " show.
The fruits are literally used as candles.
So they must contain heaps of oil/resin (??)
They seem to be grown in a VERY wide range of climates from Canberra to Queensland.

Kernels of the widespread candlenut tree (Aleurites moluccana) are about 60 percent oil.
In many countries this is extracted and used in paints and varnishes, as a
wood preservative and for lighting.

The nuts themselves will burn with a sooty flame and can be pulverised and moulded into a candle.
Aboriginal people found them useful when lighting fires in wet weather and the oil is useful for fixing ochre for painting.

The nuts are also extremely nutritious, containing more than 4200 micrograms of thiamine per hundred grams.
Only certain processed yeast products such as vegemite
contain more.
However, the raw nuts have a reputation for causing stomach upsets and are avoided by some Aboriginal groups.
Others, however, roast them in the fire to render them edible. This destroys a toxin in the oil,

Aleurites moluccana, the Candle Nut, is a tree with a wide distribution.

A fast growing species, it is often found in disturbed rainforests. It is described as a bushy tree to 20 metres with a wide spreading crown. Distribution is north-eastern Queensland and the Pacific Islands.

It makes a suitable shade tree and a good ornamental with its large leaves and attractive white flowers.

Making Biodiesel ...... Why?
At VegieCars, we prefer to modify the Fuel System rather than the fuel.

The diesel engine was originally designed by Rudolf Diesel to run on vegetable oil, and later came to be run on mineral fuels.
He thought that this engine could assist farmers to be more self sustaining, and not have to rely on outside inputs for their mechanisation.
Today most farm vehicles have a diesel motor, which many farmers could be operating from resources grown on their own farm!

Why are biofuels getting this sort of publicity. No one is upset about Brazil which practically runs on ethanol, or even the (once disasterous environmentally) Indonesian Oil Nut industry.

O, I know- because Aid is tied to US goods?

Biofuels: A Lose-Lose Strategy.

By Stephen Leahy, IPS, January 27, 2008

DEVELOPMENT: Biofuels a Lose-Lose Strategy, Critics Say

U.S. biofuels production is driving up food prices around the world, giving billions of poor people a very good reason to hate U.S. policy, say environmentalists.

"The U.S. has led the fight to stem global hunger, now we are creating hunger," said Lester Brown, president of the Earth Policy Institute, an environmental think tank in Washington.

The booming U.S. ethanol industry is diverting enormous amounts food into fuel: 81 million tonnes of grain in 2007 and 114 million tonnes this year, equaling 28 percent of the entire U.S. grain harvest, Brown told IPS. Previous eras of high grain prices were mainly the result of bad weather, but these price hikes are the result of government policy.

More like criminal. Marijuana could provide fuel and fabrics as well as the medicinal uses. The waste growing cotton alone is shameful.

I am liking the hybrid poplars too I mentioned earlier; they keep showing up with many uses, including remidiating contaminated ground.

Yes the big agri-businesses here are getting out of cotton and into almonds. (?!) There just isn't enough water on the planet for cotton, but especially here

Fascinating how resilient nature can be to the crap we are giving it. I think the count is well over 60,000 new-to-the-planet, man-made chemicals now

Ususally pumpkin is eaten by Yanks in pies during the Fall/Winter holidays. For regular meals, this Yank grows and eats acorn squash. This year I learned that if you have them around long enough, they turn pumpkin orange.

Not to mention pumpkin seeds, which are found at every grocery store and gas station in my area.

My mom used to cook the pumpkin itself and we would eat it like a squash.

I wonder, how much oil do pumpkin seeds have?

[Michaelangelica]

Growing Pumpkin seed for biofuel. i don't think so.
it might be OK for hootch/distilling= fuel + fun?

We traditionlly bake it with the 'Sunday Roast' dinner. but it is now put it on high-class pizza (caramelised).
Every restaurant has its version of Pumpkin soup in winter
The favourite varieties are Butternut (a small variety), Queensland Blue and Japanese. In fancy restaurants the soup is sometimes served in hollowed-out baby pumpkins.

Editor’s note: This is the first in a three-part series on biofuels. The series will look at problems with the current industry, explore how family farms and local economies might play in a better model, and offer how-to advice for creating and sustaining that model. Part 2 will run mid-August.

June 30, 2004: The biomass fuels industry is exploding in the wake of war in Iraq, a country touting the second largest oil reserve on the planet. The Organization of the Petroleum Exporting Countries (OPEC) has initiated a slowing of oil production and the Pentagon warns us about the eminent dangers of global warming and greenhouse gasses. Fuel prices continue to rise while fuel consumption steadily increases.

In searching for solutions to these challenges, renewable and cleaner-burning biomass fuels such as ethanol and biodiesel are gaining ground with environmentalists, economists, farmers, and the general public. However, it seems good public relations and government support for biofuels are being exploited by the corporate giants now forwarding commercialization of the technology. The current agribusiness model for biofuels’ cycle from the farms to vehicles is more a house of cards—and a profitable one until it collapses—than a logical fuel infrastructure.

Biofuel Denialists?

We had a comment a few days ago from someone taking us to task for letting up on Biofuel. Yet haven’t we been beating the drum the loudest? In our post “Reforesting vs. Biofuel” the reader will see links to just a few among dozens of reports posted here, warning how carbon credits fund rainforest destruction which causes climate change. Here is an excerpt:

“Our concern for what we consider to be a global catastrophe is well documented, in posts such as Deforestation Diesel, Brazilian vs. Californian Ethanol, Biofuel Monocultures, Biofueled Global Warming, Biofuel is NOT Carbon Neutral, Biofueled Deforestation, Ethanol & Water, Biofuel or Biohazard?, When Green is Brown, Is Biofuel Water Positive?, and many others.

What Crop is Best for Manufacturing Biofuel on a Small-Scale?
Jetta Wong

Q: We want to grow, harvest and produce our own crop to manufacture our own biofuel, for our farms. What crop do you recommend? We've been looking at sawgrass. –Joseph from Tempe, Arizona
A:

Whether you want to grow a feedstock, such as sawgrass, for your own 'on-farm' use or for commercial facilities it is important to answer several key questions before embarking on the production of bioenergy feedstocks. Anyone interested in producing bioenergy should take these questions into consideration even if you are in a 'biomass rich' state.

These questions to think about include:

1. What feedstocks do you have available or that could be available? How are these feedstocks currently being used or disposed of?

One other hard reality is that Americans consume more than 320 million gallons of gasoline a day, and there’s not a biofuel crop on the planet that will replace the gasoline anytime soon, Goodman says. Yes, corn is a viable ethanol source that has been proven time and time again. But even under the most ideal conditions, it would take an additional 400 million acres of corn to produce the ethanol required to replace the gasoline currently consumed annually — basically, all of the open land currently available in the United States, including pastureland, he says.

"At the margins, we’re going to use this stuff," says Goodman. "It’s going to ease our dependence but it’s not going to be a panacea based on the technologies we have available now.
. . .

Researchers stress that they have every reason to believe that some profitable way will be found to produce biomass ethanol on a large scale. But for now, the search continues.
. . .

One especially appealing factor associated with canola is that it could be grown in winter, much like wheat, so that farmers would be freed up in the summer to raise other crops, he says.
. . .
On the other hand, there are low-quality peanuts, known in the business as seg 2 and 3 peanuts, which have traditionally worked to depress the overall price of peanuts. Why not press them instead — into oil that eventually could be processed into biodiesel? Goodman asks.
. . .
"There is a pile of cottonseed in every gin in Alabama," Goodman says. "So why can’t we have a mill for extracting oil, which would be worth about 40 cents a pound."

Change crops for greener biofuels, scientist says
Last Updated: Friday, January 18, 2008 | 5:56 PM ET

Canada should be looking at different crops for biofuels because the original reasons for promoting ethanol have changed, plant physiologist David Layzell said.

The use of food crops like corn to make ethanol is pushing up food prices and consuming a product that can sustain people.

Switchgrass has potential as a biofuel that doesn't reduce food supplies, David Layzell said.Switchgrass has potential as a biofuel that doesn't reduce food supplies, David Layzell said.

Instead, Layzell told CBC.ca on Friday, Canada should be looking at crops like poplar, willow, switchgrass or hemp as fuel sources.

"All you want is the energy," he said.

Crops that produce "more kilometres per hectare," don't reduce food supplies and don't take valuable nutrients out of the soil are what are needed.

Wheat can power 5,000 vehicle-kilometres per hectare per year, biodiesel 10,000, cellulose about 15,000 and biomass-to-liquid systems (whereby organic material is converted into a "synfuel") 25,000, he said.

4 Common Myths About Biodiesel and Food

There are many articles in the news these days about biodiesel and other biofuels. The myths and misconceptions about biodiesel have propagated largely due to lack of understanding about the various forms of biofuels. Ethanol, for instance, is a biofuel that has many drawbacks, most importantly a low net energy gain. Our blog focuses on biodiesel because that is our area of expertise. With that in mind, this discussion will focus solely on the common biodiesel myths.

Myth 1:
Biofuels use valuable arable land that should be used for growing food.

Fact:
The two main crops used in North America to produce biodiesel are soybeans (US) and canola (Canada). The oil is extracted from the soybean and canola seed, which is then processed into biodiesel. Soybeans are actually grown for their protein, and the lesser value oil co-product only makes up 18% of the output. Of the total soy oil production, only 5% of it is currently used for non food production such as biodiesel. The increased demand for biodiesel made from

Manufacturing biodiesel from algae - The way forward?

Printer Friendly Version Print Article

Biodiesel has usually been made from the oil pressed from agricultural crops such as corn, soya, and rapeseed. However there is not enough arable land on the earth's surface to grow sufficient corn to replace the amount of fossil fuel oil we use today, let alone tomorrow. There are alternatives such as Jatropha, an amazing plant which grows on the worst soils and has seeds with an oil content of well over 30%, but again enormous swathes of the planet's land would have to be dedicated to growing this crop.

Editor's Note: With every new technology there is a lot of hype, especially when it is green technology. Biofuel is no exception. In the realm of new green energy technologies not only is the holy grail of abundant energy held forth by entrepreneurs to investors as an irresistable temptation, there is also the claim that we will save the planet. Heady stuff.
Algae are microscopic, single-celled plants, growing in an aqueous environment.

In defence of the humble coconut

By Sarina Locke

Tuesday, 29/01/2008

From massage oil, to driving an engine, cooking your food and lighting the lamps, the coconut is a "source of life," particularly in tropical Asia and the South Pacific. The milk and the "meat" are also highly nutritious, and studies have shown the oil has anti bacterial and anti viral properties.

But Dr Dan Etherington says multinational business who have a vested interest in promoting other, hydrogenated vegetable oils, like margarines, have convinced western medicine that coconut oil is bad for you, because it's a saturated fat.

Dr Etherington says in fact there is considerable evidence to show diets rich in coconuts are healthy, and it's only once people adopt a western diet full of lard and dairy food, that they become obese.

For 25 years Dr Dan Etherington was an agricultural economist in the Research School of Pacific and Asian Studies at the Australian National University, an overseas aid advocate and for the last 16 years he's developed and manufactured a coconut press with his company Kokonut Pacific, so villagers on South Pacific Islands can make their own oil.

He's been recognised for that work with a Member of the Order of Australia this year.

Dr Etherington says coconut oil is used for the fat in milk for premature babies, because it is rapidly metabolised and elite athletes use it for quickly recovering energy.

"But for some reason, the Heart Foundation continues to say that for normal people it's terrible and it'll do great damage."
. . .
With a ratchet action, the piston of the press squeezes out the coconut oil. Dried coconut contains 66 per cent oil, and two kilograms of dried coconut will give you one litre of oil.

Bio-crude turns cheap waste into valuable fuel
Reference: 08/09
CSIRO and Monash University have developed a chemical process that turns green waste into a stable bio-crude oil.
4 February 2008
The bio-crude oil can be used to produce high value chemicals and biofuels, including both petrol and diesel replacement fuels.

“By making changes to the chemical process, we’ve been able to create a concentrated bio-crude which is much more stable than that achieved elsewhere in the world,” says Dr Steven Loffler of CSIRO Forest Biosciences.

“This makes it practical and economical to produce bio-crude in local areas for transport to a central refinery, overcoming the high costs and greenhouse gas emissions otherwise involved in transporting bulky green wastes over long distances.”

The process uses low value waste such as forest thinnings, crop residues, waste paper and garden waste, significant amounts of which are currently dumped in landfill or burned.
