Biomass Biochar vs Others

Biochar is made by heating organic material to a temperature of 400 – 800°C under the absence of oxygen. The process used is called pyrolysis.

Biochar can be made from a much broader range of materials than charcoal can. Crop residues, manures, and wood are all potential feedstocks. Oxford Biochar is only composed of 100% wood sourced from sustainable British woodlands.

About Biochar

What is the difference between Biochar and Charcoal? Biochar is not used as fuel and generally measures 0-30mm in any dimension. The best Biochar is created from mixed hardwoods. We don’t add mycorrhizae or fertilisers to our Biochar, as soils harbour different species of mycorrhizae. If it’s used in the feedstock, you are guaranteed that it is 100% pure.

Oxford Wood Biochar is pure and created from known sources that have been certified by the department of agriculture, so you know what we sell is kind to the environment. We guarantee that you will get the best Biochar, because we create the best Charcoal. As Oxford Biochar is a direct bi-product of our Charcoal process, it not only reduces our waste but allows us to give back to the environment.

Straight’ biochars (non-enriched) are most suited for aeration of soils which are at risk of periodic flooding or ‘problem soils’ which are too dense or poorly drained..

Grading & Packaging

We control 100% of our processes, from feedstock sourcing to manufacture to bagging and grading. Above all, we don’t import any components. We have plenty of experience and can supply orders of any size.

We grade Biochar according to the recommended application. However, you can mix and match to your requirements.
