Biomass Management

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.

Staggering amounts of waste going to landfills:

All these unwanted materials can be turned into biochar!
