Our Biochar Production Process

Creating high-quality biochar starts long before the final product reaches the bag. At B10 Char, every step — from sourcing local waste wood to our final safety checks — is designed to deliver a clean, consistent, and reliable product. Our process follows a carefully controlled sequence of preparation, pyrolysis, and post-processing, ensuring that every batch meets the highest standards of quality, stability, and carbon integrity. Below is an overview of how we transform raw biomass into premium biochar through a transparent, science-driven production process.

Our Process Explained

Creating high-quality biochar starts long before
The final product reaches the bag. At B10 Char,
every step — from sourcing local waste wood to
our final safety checks — is designed to deliver
a clean, consistent, and reliable product.

The process follows a carefully controlled sequence of preparation, pyrolysis, and post-processing, ensuring that every batch meets the highest standards of quality, stability, and carbon integrity.

Below is an overview of how we transform raw biomass into premium biochar through a transparent,
science-driven production process.

Step 1:
Incoming Wood

Our wood is sourced locally within a 50km radius,
all waste, from FSC compliant sawmills (though
not all of our wood is FSC Certified).

As the wood comes in, the quality of the material
is inspected and tested, before being approved
to be processed into the highest qualities of
biochar.

Step 2:
Pre-Processing

Shredding

Before the woodchips can enter the process, we need to make
sure that the woodchips all have a (relatively) even size.
To do this, we shred our wood to matchstick like pieces.
This way we can ensure that the quality of our biochar is
consistent.

Drying

All incoming wood has a different moisture content on arrival. In order to prepare the woodchips for processing in our reactor, the wood needs to be dried to a moisture content of around 15%. In this way, we can keep the pyrolysis process in our reactor stable.

Sieving

After the drying process is complete, the freshly dried material is sieved to remove the fines (mainly sawdust) from the biomass. This is an extra process to ensure we get a clean feedstock for in the reactor, and keep our whole process consistent.

Step 3:
Processing

Reactor
The shredded, dried and sieved biomass then makes its way into the reactor. The reactor is kept airtight to ensure the biomass is not burned. The pyrolysis process is done at high temperature for up to 15 minutes.

Step 4:
Post-Processing

Cooling

The freshly made biochar is cooled down back to ambient temperature through a set of cooling screws with water jackets. This ensures that the biochar does not alight when it comes into contact with oxygen. After the biochar is cooled, it leaves the final airlock in stable form.

Weighing

The dry biochar is then weighed to confirm the exact amount of carbon in every bag.

Quenching

Biochar is sprayed with water to ensure safe handling and transport before leaving the factory.
