Renewable oil by Jean Laigret

[Christophe]

There is an article on Laigret on Wikipedia: http://fr.wikipedia.org/wiki/Jean_Laigret

If kk1 is motivated to complete it with our "discoveries", I put a link to the Laigret Project and to this subject.

[Capt_Maloche]

The links at the end of the page on wikipedia are interesting,

There are already two links on econology and a link to quantum equally interesting

it lacks the link to archiving documents on econology

When will the first experience?

By cons, why not do as laigret, ie recover the bacteria or there are?

Ben is still the bacterium of gas gangrene ...

Ben is still the bacterium of gas gangrene ...

This is why it is everywhere ... or almost (otherwise gangrene would be much harder to "nab") ... but obviously not isolated as necessary in the Laigret process ... except in gangrene tissues maybe ... Yuck ...

[xboxman4]

It could be isolated if it provided a favorable environment that its development (in other words unfavorable to the other bacteria)!

Or have a microscope powerful enough to see and isolate it, and then grow it!

By cons it is partly responsible for the fermentation of dead plants (compost for example)?

[Christophe]

That's why Laigret sterilized the growing medium before sowing it with perfringens!

In terms of isolating bacteria or bacilli: there are organisms for this and it does it better than we can hope to do by ourselves! The Institut Pasteur is one of ...

It's as if you wanted seeds or strains of microorganisms (micro algae): the Museum of Natural History stores thousands (millions?) ...

[Cuicui]

By cons it is partly responsible for the fermentation of dead plants (compost for example)?

It is likely that perfringens do not participate in composting, which is the work of aerobic bacteria. This is the reason why a pile of compost must be ventilated.
Perfringens is an anaerobic bacterium. The oil it produces is probably not good for plants ...

British Airways will fuel waste
March 15, 2010

Kerosene produced from household waste, this will become reality in 2014 with British Airways. The airline has partnered with Solena Group, a bioenergy specialist, to build a biofuel plant in East London. The first of its kind in Europe, the facility will produce 73 millions of liters of fuel annually thanks to the treatment of 500 000 tons of household waste. British Airways commits to buy all the production from the site. The London authorities see this project in a positive light: it will reduce the amount of waste sent to landfills and will reduce the cost of waste management.

23-02-2010 Biofuels from waste for British Airways

By biofuel is generally meant fuels from specially grown plants (beet, rapeseed, etc.), but household and industrial waste is a significant source of energy. If these are most often valued in the form of heat or methane, Solena Group has been working for several years for their recovery in the form of fuel, especially kerosene for aircraft.

The process sees the gases, obtained from the high temperature treatment of the waste in a gasifier, be converted into biofuel and naphtha (a substance used as a petroleum fluidiser by the oil industry). The yield is such that the annual conversion of 500 000 tons of waste would provide 73 million liters of kerosene. Also, in partnership with British Airways, the company is working to build a dedicated plant in East London, whose production should be fully acquired by the airline from 2014.

In addition to producing 'green kerosene', the site would produce 20 MW of electricity from the process gas residues, while solid waste alone could be used as an alternative to aggregates in the construction sector.

Ultimately, according to Solena and British Airways, compared with conventional landfill and kerosene production from the oil sector, the overall potential for reducing CO2 emissions could be around 550 000 tonnes per year. A total that is subdivided into 250 000 tons through non-landfill waste, 145 000 tons on the full life cycle of the fuel produced, 86 000 tons through the production of electricity and 72 000 tons for the production of naphtha.

If the process appears 'on paper' more than attractive, it remains to be seen what will happen concretely in four years. That said, to relativize the apparent importance of the figures advanced, the 73 million liters of biofuel promised represent only 2% of the current needs of British Airways at London-Heathrow airport ...

Thanks to a new process that transforms the remains of chocolate manufacturing into biofuel, chocolate lovers will be able to succumb to their "cute sin" without feeling guilty.

This new fuel manufactured by the British company Ecotec results from the transformation of chocolate manufacturing waste, transformed into bio-ethanol and mixed with a vegetable oil to give birth to a bio-diesel.

The 26 next November, a cargo ship that will work with this original bio-fuel will leave the port of Poole November 26, south of England to perform a humanitarian mission in Mali. It should take three weeks to reach Timbuktu, where it will unload a small biofuel production unit in collaboration with the local NGO MFC.

"Chocolate residue was normally used in the fields. But now it's used as an organic essence," said Andy Pag, tour operator.

"This shows that there are biofuels that are not harmful to the environment and that it is not necessary to convert conventional diesel engines to use them," he added, adding that "gases exhaust will not smell of chocolate ".

[Christophe]

Interesting and even astonishing for the leftovers of chocolate making (the picture is misleading) turned into bioethanol (probably a very low yield) but none is, I think, based on the use of Perfingens.

Well now that the association is created should see to re-activate a little project Laigret ... no?
