@Mihies @gandalf_der_12te Yes it is. The waste from biomass can be used as fertiliser for new plants, so a circle is formed. One tree is not quite the right model, you could think instead about managed forests where older growth is harvested and new growth is always in various stages, from saplings to ‘ready next year’. Carbon from the biomass process is used by the new growth.
