Question about carbon

[Paddy]

If you grow trees they absorb CO2 from the atmosphere.

If you chop the trees down and burn them, you are left with soot.

How much of the Carbon absorbed is released on burning the trees if you capture all the soot left over?

Not scientific but…

Numpty relative planted some Willow trees in a small garden. At the time of planting, the garden was about two inches below the path. Fifteen years later came back to cut the trees (now about 30 feet high). The foliage hand built up the top soil to well over an extra four inches covering the path. What ever is burned and leftover carbon is far less than the tree has absorbed during its life.

Using a woodburner at home, there is only a minimal amount of white ash left over and nil soot because dry wood is burnt at high temperature.

Trees are good at absorbing CO2, England has lost 10% its trees in twenty years under government building policy.

The amount of carbon isn't changed by growing and burning. It's either left unburnt (probably combined with some other element such as hydrogen) in the soot or combined with something like oxygen in the air and wafted away.

I'm burning my old Bonsai and I was worried about my Carbon footprint.

Perhaps I'd be better off jumping into my 5.7L V8 and dropping it off at the recycling centre.

That depends on the fuel / air mixture and the efficiency of the combustion process. This would all be related to the relative Ash%, Carbon% of the input fuel and the efficiency of the burn, measured as a resultant Carbon in Ash content, i.e. the unburnt carbon. The remaining carbon is emitted as CO2. I can provide detailed formulas if you need but I suspect your trolling ....

Is this an African or European tree?

Work it out. What exactly are you burning?
