The Meghalaya Pollution Control Board (PCB) has ruled out pollution from an ethanol plant in Byrnihat, following public concern triggered by social media posts alleging emissions from the unit. The probe came after Byrnihat topped the list of the world's most polluted metropolitan areas in a 2024 report.
Investigation and Findings
The PCB conducted inspections and stack monitoring at the plant, which is located in the industrial area of Byrnihat. According to officials, the board found no evidence of violations of emission norms. The plant was found to be operating within the permissible limits set by the board.
"We have thoroughly examined the facility and its emissions. The ethanol plant is compliant with all environmental standards," a PCB official stated. The board's report, released on June 30, 2026, confirmed that the unit's operations do not contribute to air pollution in the region.
Context of the Concerns
The concerns arose after social media posts circulated images and claims of thick smoke emanating from the plant. These posts gained traction, especially given Byrnihat's ranking in the 2024 World Air Quality Report by IQAir, which listed it as the most polluted metropolitan area globally. The report had highlighted high levels of PM2.5 and other pollutants in the area.
Local residents and environmental activists had demanded a thorough investigation, leading to the PCB's intervention. The board's findings aim to address these concerns and provide clarity on the plant's environmental impact.
Impact and Reactions
The PCB's clearance is expected to alleviate fears among residents and stakeholders. However, some activists remain skeptical, calling for independent audits. The plant's management welcomed the report, reiterating their commitment to sustainable operations.
Byrnihat, located on the border of Meghalaya and Assam, has been a focal point of pollution debates due to its industrial clusters. The 2024 report had spurred calls for stricter regulations, but the PCB's findings suggest that not all industrial units are contributing to the problem.
