Pyrolysis and processing
Suitable biomass is heated in a controlled process to produce biochar and heat. Feedstock preparation, drying and biochar handling are specified around your operation.
Distributed biomass energy systems
CapChar develops integrated biomass energy systems for farms, estates and rural businesses. We combine pyrolysis equipment with CapChar heat batteries and carbon-recording infrastructure to support useful heat, biochar production and eligible carbon removal.

For drying and suitable site heating applications.
Thermal storage connects production with demand.
Biochar, backed by a measured carbon-removal pathway.
Start with your site
Managing woody residues can take space, time and money. At the same time, your business may be buying energy to dry products or heat buildings.
We start with the material you have, the heat you can use and the economics of your operation. Feedstock preparation, moisture and particle size are part of that assessment — alongside labour, space and site requirements.
The result is a system designed around useful outputs and a practical operating model.
One integrated system
We combine pyrolysis equipment with CapChar thermal storage and carbon infrastructure to develop a complete site solution.
Suitable biomass is heated in a controlled process to produce biochar and heat. Feedstock preparation, drying and biochar handling are specified around your operation.
Our thermal battery is designed to capture and store heat from pyrolysis, helping match heat production to drying or heating demand.
Digital monitoring, reporting and verification (dMRV), the Biochar Carbon Code and registry connect production records with evidence of durable carbon storage.

Pyrolysis produces heat and biochar from suitable material.
Recovered heat connects to the heat battery and suitable drying or heating demand.
Biochar handling and testing connect production with an eligible end use and durable carbon storage.
dMRV supports the records, the BCC sets the methodology and the registry provides public records.
A simplified system overview. Carbon removal depends on eligible material and end use, project emissions, testing and required verification; the flow does not guarantee credit issuance.
Built around real demand
Explore how local woody residues could support on-site drying, heat use and biochar production.
Assess an integrated route for suitable chip streams, with recovered heat used in drying operations.
Develop production, processing and carbon-recording requirements together, with the intended biochar market in mind.
Scale to suit the opportunity
We develop integrated pyrolysis technology around suitable biomass and a practical use for the heat. Talk to us about feedstock, throughput, labour and budget to assess the fit.
In developmentWe welcome requirements from smaller farms and businesses. Tell us your material volumes, available labour and budget so we can assess the opportunity and inform our development.
Evidence from feedstock to end use
CapChar connects equipment with the records and methodology needed to support a credible carbon-removal project.
Our beta platform supports the capture of feedstock provenance, production measurements, sampling and testing records, and evidence of biochar end use.
The BCC sets out CapChar’s methodology for quantifying and documenting eligible biochar carbon removal, including the project’s emissions.
The CapChar registry records issued Biochar Carbon Units. Eligibility and issuance depend on the required project evidence, testing and verification; producing biochar alone does not guarantee credits.
Explore the registry ↗Learning in the field
Our development builds on pilot work in Cornwall with Tom Previte and Restord, followed by our work with Carbon350 near Petersfield in Hampshire.
These projects inform the integration of biomass conversion, heat recovery, thermal storage and carbon recording. These lessons inform our ongoing development of integrated pyrolysis, heat recovery and carbon-recording solutions.

Featured on BBC Panorama
CapChar was featured in BBC Panorama’s exploration of technologies tackling climate change.
The programme introduced our work on biochar and its potential to store carbon, bringing the story of local biomass and carbon removal to a wider audience.

Practical questions
CapChar provides equipment integration, heat batteries and carbon infrastructure. The system brings together pyrolysis, heat recovery, thermal energy storage and carbon recording around a customer’s site.
Project operators produce and market their own outputs. CapChar supplies the technology and infrastructure that support their operation.
Smaller-scale requirements remain in development and are not currently available to order. CapChar welcomes requirements from smaller sites to inform future development.
