Dry pruning waste (wood for carbonization)
Dry branches and wood from pruning, used as feedstock to make charcoal or biochar.
Characteristics
- Low-oxygen pyrolysis at about 400–500 °C favours char formation.
- The resulting biochar is porous, carbon-rich and very stable in soil.
- Its large internal surface holds water and dissolved nutrients.
- It retains roughly half of the carbon in the original biomass.
Role in the preparation: Once carbonized, it provides a porous material added to bokashi or compost as a carrier for moisture, nutrients and microorganisms.
Caution: Carbonization produces smoke and fire risk: use suitable equipment away from dry vegetation, respect local burning bans, and wear a mask when handling charcoal dust.
