ride or eat?

Apart from a few farmers or a very local production, it is not the crude vegetable oil of sunflower or rapeseed, even used at 80% which will make it possible to do without Mister Petroleum.
On the other hand, in a slightly more "industrial" fashion, I suggest the following approach (hoping not to reverse certain phases too much or forget some)
1 / recovery from wastewater treatment plants / or animal waste, on the one hand of methane and on the other hand of "dry" organic residues, via digesters
2 / above ground cultivation of sunflower or rapeseed varieties or? (plants which could be tropical, see below), which give a good oil yield in the plant
If in addition, under temperature conditions, nitrogen inputs and irrigation, varieties are found allowing several annual harvests, we take immediately;
3 / the recovered gas is used to heat the greenhouse if necessary (hence Adoc tropical plants), dry residues are a very good fertilizer
4 / "ladder" crops (see the photos of this Japanese gardener who cultivates ten times more lettuce for the same area by growing them "stepped")
5 / the culture above ground uses very little water (misting effect) very few inputs (and we have available fertilizers from recycling point 1 /), and requires, all other things being equal, 10 times less area to be multiplied by the number of possible annual cycles according to the varieties.
What is more, we no longer speak of "cultivable" surfaces, we can even locate production units near major places of consumption.
6 / the oil is obtained by cold pressing;
7 / we filter a max
8 / we recover the plant waste, either for oil meal, or for biogas, self-consumption or to supply the network
9 / we refine, generalize, market the GO / HVB "bi-fuel" kits, to avoid most of the problems, including in the most modern Diesel engines
and 10 / as we are good citizens, we get taxed, but at a much lower rate than the (ex) TIPP : Cheesy:

Variant with "algae", interest in many annual harvests, hence even smaller surfaces, question, can we easily supply CO2 (via methane see 1 /?), The main nutrient for the growth of algae?
: Cry:

Sorry for our farmer friends, it's less "funny" :!:

Hello,

This is all very well !!
But if we reflected a little more:
The sunflower is greedy in water, the rapeseed too.
They are annual plants with a temperate climate!
Every year, it is necessary to cut, plow and replant ...

The JATROPHA is a plant of semi-desert climate (one lives there slowly but surely)
No need to replant it every year ... (less waste)
Its oil yield is much better than sunflower or rapeseed. (35% to 40%)
It could very well occupy the obligatory "fallows" ...
Inconvenient it freezes faster (approx. 0 ° C)

Long live the jatropha for the oily !! : Mrgreen:

I confirm what said above.

my trash at 100% hv consumes 6,5l / 100 for 6L at GO.

yes many people do.
me too 100% bi-fuel. sunflower oil, rapeseed, olive, peanut, a little palm and even once with my grandmother's expired nut oil! (thank you granny).
for the cost in the 300roros too. reimbursed after 300 liters filtered, consumed. or 500kms !! : Cheesy:

Seen yesterday on Arte a report on the oil extracted from the seeds of jatropha (non food), better yield than rapeseed, used as biofuel, also allows the reforestation of desert places (but still needs a minimum of water)

Jatropha is mentioned at the end of this article dating from ...1949...distressing...

Make oil from biomass




by Cuicui » 16/05/08, 19:35

There is an article on econology about making petroleum from biomass, but I couldn't download it.
However, here is another link:

http://www.lagrandeepoque.com/LGE/content/view/879

Exploitation of the only biomass (sewage sludge, various waste which we do not know how to get rid of) would be more than enough to produce enough oil for road traffic.
Our "dear" government wants to make fuel with wheat, corn and beets.
How to make it possible for individuals to manufacture their oil from waste?

1) transform them into biogas

2) transform it into a liquid using the fischer tropps process


----------

1) is possible for an individual (waste water kitchen wc):
http://www.nrjrealiste.fr/biogaz/biogaz2.html

2) is hotter already ... it's a bit like a gas plant! unless there are techniques on the net?
otherwise you have to comrpess the gas, not very good performance / autonomy I think ...

We look forward to seeing you! Jonule, to revive the subject.
The technique to produce oil rather than biogas seems to exist, it is old: it is that of Dr. Laigret. See :
http://www.lagrandeepoque.com/LGE/content/view/879
It is based on the use of bacteria.
"What has become of Doctor Jean Laigret?
We will not elaborate on the reasons which made his major and historical discovery fall into incredible oblivion. But it is clear that it could hardly, in 1950, serve political and financial interests… What about our very problematic times? A man of talent and truth, little concerned with his personal career, he was nonetheless already known for his work on tropical diseases when he undertook to study methane fermentation. He had directed important work and was the Institute's correspondent when he died in 1966, now 40 years ago. "

This obviously does not interest the government. Strongly a cheap process within the reach of individuals ...
