Biochar is any organic material or 'biomass' that has been cooked at a high temperature with limited oxygen present.
This process is also known as pyrolysis.

"This 2,000 year-old practice converts agricultural waste into a soil enhancer that stores carbon for hundreds of years, boosts food security, and increases soil biodiversity.


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 your soil?

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.


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.


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.

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

We can do it, contact Tony


We can bring a Retort to you.

A Biochar demonstration is an interesting and informative addition to an event.
