Bangna Starch Wastewater Treatment and Biogas Utilization Project (300084) (GS565 CER to VER conversion)

Audit Analysis

A Thai biogas-electricity project (CDM 300084, converted to Gold Standard VER) with VVB-confirmed additionality and a measured project-specific baseline, but undermined by an extensive list of material findings including formula errors, calibration gaps, and missing utility reports that required ten corrective actions and three clarifications. The absence of a stated buffer pool, unaddressed permanence, and a 0% leakage deduction with only a 'deemed negligible' justification leave meaningful gaps in the integrity and claim-safety picture.

Project Description

Red Flags

• ⚠Ten corrective actions (CARs) and three clarifications (CLs) were raised in the 2018 verification report, including formula errors in the ER spreadsheet, missing PEA reports for July–October 2016, and calibration inconsistencies for the biogas flow meter and COD colorimeter.
• ⚠Permanence and reversal risk are explicitly 'not addressed' in the available documents, and no buffer pool percentage is stated.
• ⚠The 2018 verification report records a 0% leakage deduction justified only as 'deemed negligible,' while the 2013 verification report does not address leakage at all — an inconsistency that weakens the justification.
• ⚠CORSIA eligibility is confirmed while CCP status is not stated, creating a dual-channel allocation risk that is not resolved in the available record.
