Biochar production
Quality biochar is produced far beyond Europe - and quality standards should reach just as far. The World Biochar Certificate (WBC) extends the European framework to a global context, keeping its strict, science-based quality requirements while setting aside the criteria that derive specifically from European legislation.
Producing biochar to WBC guidelines ensures that biomass is sourced and used sustainably, and that production is carbon-positive and compliant with national emissions regulations. Biochar quality is assessed at least once a year. The standard offers three classes: Premium, Agro, and Material.
Biochar quality and production methods vary widely, and not all are sustainable - or even safe, where heavy metals and other contaminants are concerned. Customers around the world increasingly want assurance that the biochar they buy meets real safety and sustainability criteria. WBC certification provides that guarantee, for biochar used in agriculture and in composite materials.

Registration Process
After an initial contact via the email address [email protected], the next step is to register your interest in beginning the certification process.
Certification process
The Certification Process involves a Technical Pre-Audit of the biochar production company including material process flows and emissions, a review of the pyrolysis technology and the resulting biochar as well as a review of the production company’s sampling plan. Following a successful pre-audit, companies may register their first-year production batch. A third-party on-site inspection is the final step in the certification process. Once all steps have been successfully completed, the sale of WBC-certified biochar can begin.

Technical Pre-Audit
In the technical pre-audit, Carbon Standards will review the pyrolysis technology against the specifications in the guidelines and, if necessary, offer advice on improving the biochar production process. Carbon Standards also checks whether the WBC guidelines for the sustainable production of biochar have been thoroughly understood by the biochar producer with all necessary processes in place to implement them.

Representative Sample
Producers must take a representative sample for each batch and have it tested in an endorsed laboratory.

On-going Production
Biochar production batches are valid and certified for up to one year. Producers will be required to register new production batches of biochar made from the same feedstock and processing parameters annually. Each new batch will require new biochar samples to be analyzed before they can be certified. New batches will also be required when new feedstocks or feedstock mixes or new processing parameters (e.g. heating temperatures) are utilized.
An on-site inspection is carried out every year.

All endorsed laboratories and subcontractors take part in an independent biochar ring trial every year, which is organized and evaluated by DCC Delta Coal Control. Our goal is to set up an international network of laboratories for biochar analysis that work using the same analysis methods and regularly take part in the biochar ring trial testing to ensure accurate and consistent results across all endorsed facilities.
For testing laboratories interested in becoming endorsed by Carbon Standards, please review the following documents:

This document outlines the steps required to participate in a 3rd party controlled ring trial to become an endorsed laboratory for certifying biochar under the EBC/WBC standards.
This document should be used to request biochar reference samples (#1017) to begin the ring trial process. (Note: Dates on the form are related to the annual testing period.) New labs will be sent reference materials upon request and payment of the invoice.

EBC or WBC Certified biochar producers can utilize Carbon Standards’ Biochar Tool to manage all aspects of production including initiating and renewing batches, managing annual sample requirements and monitoring production volumes. The Biochar Tool can also be used during the technical pre-audit to share relevant documentation related to the pre-audit and certification process.
CERES-CERT AG is the third-party auditing body for the standards owned by Carbon Standards International.
