Biochar Bob highlights a project near DC where they are using biochar in a wetland restoration project to filter pollutants out of run-off and restore natural water infiltration to that neighborhood.

From Biochar Merchants, some great tips for using Biochar in your Compost Bin or pile.


  1. For a new pile or bin, start with a layer of biochar to catch nutrients from the compost bin that would normally seep into the ground with normal water flow
  2. Add 12 inches (or a decimeter) of compostable materials, e.g. yard waste, kitchen cuttings, egg shells, coffee grounds, etc. - alternate 'greens' and 'browns' and make sure that the particle size is fairly small -about an inch or two or less in size.
  3. Add a layer of biochar (no more than 1/2 inch)
  4. Keep building the compost as normal
  5. Keep in mind, that turning the compost and keeping it moist but not too wet will help change it into the magical dark fertile compost we love.

Some good reasons to compost with Biochar

James Cook University in Australia are working on a research project where biochar is specifically mixed in at an early stage of the composting project, COMBI-mix, to determine the impact on carbon sequestration and model the impacts on the agricultural impacts.
