Towards Cleaner Technologies: a process story in the Firozabad glass industry cluster

The small-scale glass industries cluster located in Firozabad, near Agra, produces an estimated 50 million bangles each day. Traditionally, units in the cluster burned coal in low-efficiency furnaces, leading to high levels of emissions. Following the Supreme Court verdict in the famous Taj Trapezium Case?, the Firozabad units came under pressure to switch from coal to natural gas as fuel.
