We describe the use of a place-based mobile pyrolysis unit equipped with an air curtain to continuously create biochar. The technology reduces the need for open slash pile burning, which results in lower emissions and fewer soil impacts. The protocol includes guidelines for site selection, loading, and quenching.

A novel Upflow Anaerobic Solid State (UASS) reactor was used for biogas production from fibrous feedstock. Digestate from UASS reactor was hydrothermally carbonized into HTC biochar in a pressurized batch reactor. The integration of the two bioenergy concepts was applied in this study to increase overall bioenergy production.
FAQs
Oxygen limitation allows heating to drive pyrolysis without fully oxidizing the biomass. Instead of converting the feedstock entirely into combustion products, the process forms a carbon-rich solid while also generating gases and liquids. Maintaining the intended oxygen-limited or oxygen-free condition is therefore central to directing biomass conversion toward biochar and supporting recovery of the other product streams.
Feedstock flow, temperature, residence time, and discharge conditions work together to influence the properties of the resulting biochar. Temperature controls the heating environment, residence time determines how long material remains exposed to it, and regulated flow and discharge help maintain stable processing. Coordinating these variables supports more consistent material properties and efficient operation.
The main operational difference is continuity. Rather than loading biomass, processing it, and removing the products before starting again, a continuous system regulates feedstock entry and product discharge while processing proceeds. This steady-flow arrangement is intended to support ongoing operation, consistent conditions, and scalable handling of biomass, whereas batch processing separates production into individual cycles.
Pyrolysis produces gases and liquids in addition to the carbon-rich solid. These co-products may be recovered for energy or other uses, allowing the process to extract more value from the original biomass than solid production alone. Their recovery also connects biochar manufacture with resource recovery, although the overview does not specify particular gas or liquid compositions.
Operation requires coordinated control of biomass feedstock flow, heating conditions, residence time, and biochar discharge. The reactor must sustain an oxygen-limited or oxygen-free environment while material moves through the process. Monitoring these linked steps helps keep conversion conditions stable, supports predictable biochar properties, and reduces interruptions associated with separate loading and unloading cycles.
It is useful when agricultural or other organic waste needs to be processed steadily rather than in isolated batches. The approach converts this material into a stable carbon product while also creating gases and liquids that may be recovered. Its ongoing operation can support scalable waste reduction and connect waste treatment with carbon management and resource recovery.
The biochar can be directed toward soil improvement and carbon management after production. Converting agricultural or organic waste into a stable carbon material provides an alternative to treating that biomass only as discarded material. In broader environmental strategies, continuous processing may support waste reduction and climate mitigation by combining material recovery with the formation of a persistent carbon-rich product.
Consistent properties make the material more predictable when it is applied for soil improvement or carbon management. Continuous systems pursue that consistency by regulating feedstock flow, temperature, residence time, and discharge rather than allowing conditions to vary between separate cycles. Stable operation also helps evaluate process efficiency and supports the development of scalable environmental applications.
