BTK
So in 1996 the Indian government banned BTKs in favor of a newer design outfitted with a single chimney roughly 120 feet high. By increasing the draft and emitting pollutants higher in the sky, the so-called fixed-chimney Bull's trench kiln (FCBTK) helps reduce worker exposures. It is now used by 40% of India's brick makers, accounting for 70% of the country's total brick production. …
