A project of biogas production from waste water of tapioca starch plant to substitute the use of bunker oil at Udornthani Province, Thailand

Audit Analysis

A CDM biogas project in Thailand that captures methane from tapioca starch wastewater to substitute bunker oil, with VVB-confirmed investment additionality and a reasonable 0% leakage deduction. Key MRV parameters (verified ERR, FNRB, usage monitoring method) are absent from the extracted record, and the baseline is project-specific rather than jurisdictional. Ten minor administrative findings at validation were all corrected, and the project delivered roughly 108% of the pro-rata ex-ante expectation over the 8-year monitoring period.

Project Description

Red Flags

• ⚠Total verified ERR is not stated in any available document, preventing independent cross-check of claimed reductions
• ⚠Baseline is project-specific rather than jurisdictional, limiting comparability and robustness
• ⚠FNRB value and usage monitoring method are not stated in the extracted record
• ⚠Grid emission factor is from 2009, which is somewhat dated for a project active through 2022
• ⚠Ten material findings were raised at validation (missing LoA, formula errors, missing monitoring parameters), all corrected but indicating initial documentation gaps
