Biomass Management

Organic "waste" is a problem across many sectors:

  • Forestry generates massive amounts of material that is difficult to market - prunings, thinnings, post-harvest residues, stumps and slash, offcuts, bark, and sawdust.
  •  
  • Horticulture has a similar set of issues with prunings, culled trees, and unsellable produce.
  •  
  • Households generate large volumes of biomass (greenwaste) that most municipalities send to landfill.

    Sewage solids/sludge from municipalities are usually landfilled. 

    Shelterbelt prunings on farms result in an annual "smoke season" as they are wastefully burned to ash.

All these unwanted materials can be turned into biochar!
