Pyrolysis
What is Pyrolysis in the Biochar Process?
The pyrolysis of biochar is a process that heats organic material (biomass) in a low-oxygen environment to create a stable, carbon-rich product known as biochar.
Unlike burning or natural decomposition, pyrolysis prevents carbon from being released into the atmosphere. Instead, it transforms biomass into a form of permanent carbon storage, making it a powerful tool for carbon sequestration.
Why Pyrolysis Matters
When organic matter decomposes or is burned, it releases carbon dioxide (CO₂) back into the atmosphere, contributing to climate change.
Pyrolysis changes this outcome.
By limiting oxygen, the process captures and stabilises the carbon, preventing emissions and turning biomass into a long-term carbon sink.
How the Pyrolysis Biochar Process Works
- Organic material such as wood or agricultural waste is heated to high temperatures (around 600°C)
- Oxygen levels are restricted to prevent combustion
- The biomass is thermally decomposed and converted into biochar
The result is a highly stable material with a high carbon content.
Below is a flow chart of the pyrolysis process:
The Benefits of Pyrolysis
- Carbon sequestration – locks carbon into the soil for the long term
- Renewable energy – heat generated during pyrolysis can be used for energy production
- Soil improvement – biochar enhances soil structure, water retention, and microbial activity
Why It Matters for the Future
Healthy soils are one of the most effective natural carbon sinks available.
By incorporating biochar into soil, we not only improve soil health and productivity, but also actively remove carbon dioxide from the atmosphere. This makes pyrolysis a key solution in tackling climate change.
EBC Certification
We are proud that our parent company, Brodie Biomass, holds EBC (European Biochar Certificate) certification: one of the highest standards for biochar quality and environmental performance.
This certification ensures that the biochar we supply meets strict criteria for:
- Sustainability
- Carbon stability
- Environmental safety
