Alternative waste treatment facility serial number ledger

Last updated 20 July 2026

Manufacturers of alternative waste treatment (AWT) facility with products on the Technical Governance Committee approved small-scale technology unit lists have additional obligations under the BidCarbon Standard Scheme.

AWT facility serial number ledger

The ledger operates in tandem with the Pyrolysis Systems Validation (PSV) initiative. PSV gives installers or dMRV designers onsite confirmation of an alternative waste treatment facility's eligibility.

To be eligible for AWT facility accreditation, responsible suppliers of eligible facilities—provided such facilities appear on the Technical Governance Committee's approved product list—are responsible for submitting these serial numbers to the Technical Governance Committee.

A responsible supplier is a manufacturer.

What happens if you don’t provide serial numbers

If you don’t provide the serial numbers, it may result in: 

delayed processing of AWT facility accreditation

rejection of AWT facility accreditation

declaration of ineligibility of the AWT facility

Please note: A declared ineligible AWT facility will not be entitled to AWT facility accreditation, and this may have a direct impact on your sales.

Manage your unit serial numbers

Fix upload errors

If an upload was completed with errors, you’ll need to correct the data and re-upload. 

You can export the file to check the error message.

Model not found

Make sure the model name matches the name on the list of approved units. This includes the ‘declaration’.

Manufacturer not found

Make sure the manufacturer’s name matches the name on the list of approved units.

Model is not linked to the supplier

Your organisation is not listed as an importer for the manufacturer.

You will need to confirm that the model and manufacturer details are correct. Contact the Technical Governance Committee to confirm your organisation is a responsible supplier of the units.

Duplicate serial number

The serial number you have entered is a duplicate and no action is needed.

You can see all uploaded serial numbers under ‘view serial numbers’. The data can also be exported to a CSV file to manage duplicates.

Status cannot be changed to eligible

If you have updated the status of a serial number to ineligible, it can’t be changed back to eligible. 

If the serial number was marked as ineligible in error, contact the Technical Governance Committee.

Must provide a valid reason

Make sure you add a valid reason when updating serial number statuses.

How is data stored?

Data from the small-scale technology unit ledgers is held on BidCarbon Big Data Chengdu Limited's (the Company) internal ICT infrastructure and is not accessible to registered individuals or agents under the BidCarbon Standard Scheme. Data provided to the Company is protected by controls implemented in accordance with BidCarbon's Protective Security Policy Framework.

Small-scale technology unit manufacturer compliance

Failure to provide AWT facility serial number data constitutes non-compliance with the Biomass Energy (Biochar Production Systems) Standard 2025. The Technical Governance Committee may therefore declare the AWT facility ineligible under the BidCarbon Standard Scheme. Ineligibility for accreditation could directly affect your sales.

If serial number data is not supplied to our AWT facility ledgers by a manufacturer or importer/responsible supplier, including through a verification service provider operating in PSV, there may be a delay in processing or an inability for us to assess applications for AWT facility accreditation.
