This documentary investigates how Byrnihat, located on the border of Assam and Meghalaya, became one of the most polluted cities in India despite being in a region known for its pristine nature. The report highlights the severe environmental and health impact of industrialization on the local population.

Key Findings and Data:

Extreme Pollution Levels: Byrnihat was recorded as the most polluted city in India in 2024, with an average PM2.5 level of 128, significantly exceeding the WHO recommended limit of 5.

Industrial Density: The area is home to approximately 80 highly polluting factories, including cement and alcohol manufacturing plants, which release toxic emissions into a bowl-shaped valley where the pollution gets trapped.

Health Impact: Official data indicates a sharp increase in respiratory issues, rising from 2,082 cases in 2022 to 3,681 in 2024, a 77% increase in just two years. Residents report high rates of cancer, asthma, and chronic skin diseases, which they attribute to the poor air and water quality.

Environmental Degradation: The documentary shows layers of black soot covering local vegetation. Despite the area being a matriarchal society with strong community ties, local families struggle with the consequences of this industrial development, which they claim has worsened significantly over the last three years.

Key Controversies:

Green Energy Irony: The factory featured in the investigation produces ethanol, the same fuel blended with petrol (up to 20%) and promoted as "green energy" by the government, creating a stark contrast between national goals and the lived reality of Byrnihat residents.

Regulatory Failure: While there have been sporadic inspections and fines, the report argues there is a lack of accountability and a long-term action plan, exacerbated by jurisdictional confusion between the Assam and Meghalaya state governments.

Edit : For the people who are putting the point that ethanol production dosen't cause significant pollution by examples of Brazil and other countries.....Let me Address that too

Ethanol itself isn't the variable. The difference is how it's produced and regulated.

Brazil's production is relatively cleaner because it uses sugarcane, which has an energy balance of about 8 to 9 units out for every 1 unit of input. The bagasse, the sugarcane waste, gets burned right there to power the distillery, so the factory is largely energy self-sufficient. No coal means no coal-related black smoke. Brazil also has decades of infrastructure, strict effluent treatment mandates, and distilleries are mostly located with enough land buffers away from dense residential zones to manage spent wash properly.

India's production is dirtier because molasses-based distilleries run their boilers on coal. That coal boiler is the source of black smoke, not the fermentation itself. The energy balance is far worse, roughly 1.5 to 2 units of output per fossil input, so you're burning a dirty fuel to make a "green" one. On top of that, there's a chronic spent wash disposal problem. Treatment technology exists but it's expensive, so many units dump partially treated or untreated effluent directly into rivers. The CPCB has known this for decades, distilleries are literally on its list of 17 most polluting industry categories, but enforcement is weak and fines are cheaper than compliance.

So the pollution isn't from ethanol itself. It's from the process fuel and waste management. Brazil burns sugarcane waste and enforces treatment standards. India burns coal and mostly looks the other way.

The question is : If they were not ready to make it entirly clean, why did they introduce and pitch it like that at the first place ?
