Tree was just a generic way of speak.
At the end we REALLY need to speak "WATHER".
We speak TREE because its common there have more celluloses than another thing ( its obvious because this they use to paper, and not another kind of "PLANT"). Specific kind of Eucalyptus, that growing fast and have a easy and good cellulose.
But still be a big problem.
Water, Soil and the better BASE for this.
Today we have this.
A good example is US using corn and soja do produce alcohol. when this is the worst thing can be used to do it. Its a waste of time, soil, water, money. Everything. They just don't use "Cana de AÃucar or Mandioca" to produce because of a INFANTILE wish of be BETTER and never admit this is bad.
When I visited a farm of CORN and a CORN/ALCHOOL refinery in US one half year ago. Was like I was in a crazy movie. ITS IMBECILE was unbelievable what I saw there. its like use OIL just to produce gasoline and all other residual they just put out and burn.
I don't have now here , iam writing. But One ton of Cana de AÃucar seems can produce 160% more alcohol than CORN. ( and can be used lather to burn at the refinery to produce energy). Mandioca can do it a lot of more ( when is peak a lot, ITS AMAZING A LOT).
Its the called, "COMPLETE CYCLE" production. the carbon emitted in garbage( energy produce ) and to produce the alcohol is 100% used at growing up of plant. When I leave Brazil 5y ago, they used to have 60% of cars using alcohol. ( and seems that 20y ago this become near 80%). ( they use this a lot of time more than 30y)
I don't know the name, but by time have a Bacteria that can Broken sugar to produce alcohol and other can broken cellulose do produce diesel. but until today they cant do it in a production WAY( and secure to) and seems this exist for a long time, 20y or more.
Today we already can use any type of leguminous plant to produce Biodisel.
I lived for 8y in Brazil and there they are pioneer in Bio combustible ( besides the fact all BIG oil company speak this is bad and do problem with food, now we with FINANCIAL troubles started in US become easy to know from where the FOOD HIGHT PRICE LAST YEARS COME). this happens in rich places like US and Europe where we have HARD subsidies to use wrong thing ( like corn and soja).
They ( Brazil) already use in industrial scale, a lot of leguminous plant to produce biodiesel. Its a law, a % of standard diesel need to have this biodiesel. ( because small farmers can produce it and in all country for different of species of farms)
Fungus, Bacterias, Or any other kind of Bio fuel, can be used and well. the problem is . WHO WANT DO IT.
RICH countries don't want and do anything to say its bad. Other side of this is the country's have a REAL wish of do it, Like Brazil, where they use this for 20y and in industrial scale, and don't disturb any kind of other farm culture.
WAS a good this discover. But again. this not a NEW thing. Its just one more that can help. IF THE BIG ONES ALLOW THIS.
