Advanced pyrolysis
At the heart of Diggin’s production lies a method of continuous pyrolysis, which developed in the UK by our manufacturer. This is an advanced technique which requires careful attention to detail and the maintenance of a low-oxygen environment throughout the process. Such precision ensures that the end product meets the highest standards of quality and consistency.
Pyrolysis - not Gasification
While continuous pyrolysis is our chosen method, it stands in contrast to the practices used by many volume biochar producers. Typically, these rely on gasification, a process characterised by higher levels of oxygen. Gasification is generally easier to operate and is primarily focused on generating heat and power, with any resulting char being considered merely a byproduct. This char has quite different characteristics to Diggin biochar.
A Microscopic Coral Reef
Our unique “Benzine Rings” create a rigid structure that acts as a permanent habitat for beneficial fungi and bacteria to thrive.
Diggin Nutrient Magnets
Unlike gasified ash, our biochar has special chemical bonds that grab onto water and nutrients, keeping them right where your roots need them.
Centuries of Stability
Our biochar is “recalcitrant.” It won’t wash away or break down. One application improves your soil structure for hundreds of years.
Purposeful Production
Our approach differs fundamentally in its intent. The design and operation of our pyrolysis plant is centred on the deliberate production of high-quality biochar, rather than treating this secondary to power output. This dedication to creating biochar as the main product leads to a material with the right physical and chemical properties to truly help soil to thrive and flourish. To enrich your earth.
Gasification
Most commercial biochar is a byproduct of power plants. It is made by partially burning wood to create electricity.
- Source Material: Various biomass waste streams
- The Result: Mostly inert ash.
- The Impact: Releases high levels of CO_{2} into the air.
- The Verdict: Great for making heat and power, poor for making soil.
The Diggin Way: Pyrolysis
We use “Continuous Pyrolysis”—a low-and-slow process that happens in a 100% oxygen-free environment.
- Source Material: Fallen ash trees
- The Result: Pure, high-carbon “Carbonite.”
- The Impact: Carbon Negative (it traps CO_{2}).
- The Verdict: Specifically engineered for soil health and carbon storage.
