Holding an event?

We can bring a retort and do a biochar demonstration.

Do you have a material that would be suitable for processing into Biochar?

We can do it, contact Tony

What is Biochar?

The following is from the:

International Biochar Institute

"This 2,000 year-old practice converts agricultural waste into a soil enhancer that can hold carbon, boost food security, and increase soil biodiversity, and discourage deforestation. The process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water.


Biochar is found in soils around the world as a result of vegetation fires and historic soil management practices. Intensive study of biochar-rich dark earths in the Amazon (terra preta), has led to a wider appreciation of biochar’s unique properties as a soil enhancer.


Biochar can be an important tool to increase food security and cropland diversity in areas with severely depleted soils, scarce organic resources, and inadequate water and chemical fertilizer supplies.


Biochar also improves water quality and quantity by increasing soil retention of nutrients and agrochemicals for plant and crop utilization. More nutrients stay in the soil instead of leaching into groundwater and causing pollution."

What can Biochar do for you?

The positive effects of biochar in your soil:

  • Biochar improves plant growth and yield

  • Saves you money (less watering, no chemical fertilisers)

  • Create a better plant root environment

  • Increase the PH, Nitrogen, Phosphorous and Potash

  • Helps fight climate change – lock carbon in the ground

  • Organic – locally & sustainably sourced

  • Improve the habitat of the moorland of Wales

During the spring and summer season we sell biochar locally to gardeners, if you would like to try some in your garden please contact us.

What do we use to make Biochar?

Molinia Caerulea is a dominating low quality grass which we harvest for processing into Biochar. Removing the Molinia grass from the moorlands improves the diversity of the habitat and lessens the risk of hill fires.

This 2,000 year-old practice converts agricultural waste into Biochar through the process of pyrolysis that heats biomass with limited amounts of oxygen present.  Surplus Molinia grass from Henfron Farm is cooked with limited oxygen at temperatures up to 500˚C in an efficient insulated retort to produce our Biochar.
