Waste to Energy Projects by Mahindra Waste to Energy Solutions Limited

Audit Analysis

This VCS waste-to-energy (anaerobic digestion) project in India has a confirmed investment-test additionality and a reputable VVB (TÜV SÜD), but the verification report reveals multiple material errors in prior monitoring periods—including incorrect default emission factors, omitted composting and digestate-storage emissions, and a miscalculated baseline—triggering eight corrective action requests. The project over-delivers relative to its pro-rata expectation (~216%), yet the history of over-crediting in earlier vintages and the absence of a stated buffer pool or reversal-risk assessment leave meaningful integrity and claim-safety concerns unresolved.

Project Description

Red Flags

• ⚠Multiple errors in prior verifications: incorrect FEC default (0 vs 1.02 MWh/tCH4), DOCf,y (0.9 vs 0.5), omitted composting emissions (880 tCO2e), and previously zero leakage from digestate storage (now 2,282 tCO2e)
• ⚠Eight corrective action requests raised during validation and verification, all closed but indicating systemic calculation weaknesses
• ⚠Reversal events explicitly not addressed in available documents; buffer pool percentage not stated
• ⚠Crediting period discrepancy: PDD states 2018-04-01 to 2028-03-31 (10 yr) while the 2025 monitoring report states 2019-05-01 to 2026-04-30 (7 yr)
• ⚠Minimum extraction confidence rated low, and one evidence document is of unknown type
