It is a welcome step from MoEFCC to reign in uncomplying brick kilns through technology roadmaps or cleaner fuel options, says CSE…
The Union Ministry of Environment, Forest and Climate Change (MoEF&CC) came up with stringent standards for brick kilns after seven years of deliberation via a notification dated February 22, 2022.
Brick kilns have been identified as a major source of pollution in many non-attainment cities, that do not fulfil MoEF&CC’s stipulated air quality requirements.
The notification has paved the way to reduce air pollution from brick kilns, according to Delhi-based non-profit Centre for Science and Environment (CSE).
What it says
It all started in October 2015 when the MoEF&CC came out with a draft notification proposing different particulate matter (PM) emission standards for natural draught and induced draught kilns.
CSE opposed the draft. It stated that state pollution control boards (SPCB) would not be able to monitor all 70-80,000 operational brick kilns in the countryon a regular basis, due to lack of personnel.
CSE thus pushed for technological change so that emissions would inherently be less. MoEF&CC, in its current notification, has mandated allowing brick kilns only with zig-zag technology or vertical shaft or use of piped natural gas (PNG) as fuel in the brick-making process.
The introduction of PNG as a fuel is a welcome step since its use in older technology like Fixed Chimney Bull’s Trench Kiln (FCBTK) will automatically reduce the PM emissions. Other salient features of the notification are…
