The message
from "Rupert \(W.Yorkshire\)" contains these words:

Burning does produce smoke whether you can see it or not. and produces
carbon dioxide and a plethora of other substances ,some of which are
highly
toxic, depending on what plant material you are burning. Composting and
mulching keeps the carbon locked in a more complex form.

However, composting releases methane, a far more potent greenhouse gas
than CO2.

Pay no attention to that man behind the curtain.

Anaerobic fermentation does the methane bit ?
