In February 2016, Bihar State Pollution Control Board (BSPCB) issued a directive to all brick kiln enterprises located in five blocks of Patna district to shift to cleaner brick kiln technologies within a year’s time. To assist the brick makers in transition to cleaner technologies, a one-year technical support programme was put in place with support from Shakti Sustainable Energy Foundation. This publication, a case study prepared by Greentech Knowledge Solutions Pvt. Ltd., documents the strategy and process of implementation of this technical assistance programme and its outcomes, and draws important learnings from it.
