Indian farmers burn waste straw, worsening Delhi air quality

Waste straw is common, especially in agriculturally developed countries and provinces. In people's traditional consciousness, waste straw is a useless waste.

But the straw is rich in carbon, so as long as the correct recycling method is used, they will become a valuable resource.

India is increasing regulations on environmental pollutants. India's Supreme Court has ordered that only government-certified environmentally friendly firecrackers can be fired during Diwali.

And the New Delhi government also ordered an extension of the construction ban. Moreover, the Indian government announced that the capital region will close unused natural gas plants until 11.2. Unfortunately, these measures have not yielded good results.

According to data from the Central Pollution Control Board (CPCB) of India, Delhi ’s 24-hour average air quality index (AQI) on the 29th reached 419, and many areas in Delhi were above 400 this morning, all in the "severe" level, and some areas even exceeded 850. The Indian government defines the AQI as a "Severe" rating from 401 to 500.

Indian Farmers Are Burning Straw

According to a report by the Prime Minister's Office of India, 35% of PM2.5 in the National Capital Region comes from smoke from agricultural waste such as straw burning by farmers in Punjab and Haryana provinces.

Some farmers told the Hindustan Times a few days ago that they had no choice but to burn straw as there was no special machinery for handling straw, or they would affect their subsequent sowing.

Burning Straw

Due to severe air pollution, Times of India pointed out that the number of patients with respiratory-related diseases in the National Capital Region Hospital of India increased by 30%, with children and the elderly most affected.

A better way to handle waste straw is Carbonization. Carbon-containing biomass materials (including straw) can be carbonized into charcoal in a high-temperature and oxygen-free closed environment, which can not only control the burning pollution of straw but also obtain high-value charcoal.

The latest news says that the government of Delhi and neighboring Northern Province Noida has ordered schools at all levels to stop outdoor activities until air quality improves.
