A workshop was held in Varanasi, India from 19-21 June 2014 to develop a standardized protocol for climate-relevant emissions and efficiency measurements at brick kilns. There were 10 participants from Nepal, India and the United States, as well as a participant from Mexico who attended the event via Skype.

Day 1 began with discussion about categorizing the kilns into four types by identifying commonalities between brick kilns around the world. This will make the measurement results more comparable. Presentations were made on these various types of kilns. Discussion in the latter part of the day focused on monitoring protocols.

On Day 2 participants made a field trip to three types of brick kilns:

  • Typical FCBTK 
  • Retrofitted FCBTK into natural draught zigzag kiln
  • New natural draught zigzag kiln with permanent roof and firing perforated/hollow bricks

The visit familiarized the participants with the design and operation of the ‘moving fire continuous kiln’ technology. They were later able to use their observations in their discussion of measurement protocols. 

Following the field visit, they discussed protocols for energy measurement in the kilns. Tami Bond and her graduate student, Ryan demonstrated the sampling kit they had developed. Participants briefly discussed the possibility of including the kit in the list of CLIAMA deliverables in the region. 

Day 3 was focused mainly on discussing the instrumentation and ambient measurement for determining the contribution from the brick industry, along with the social challenges involved in it. Participants also discussed how best to use the protocol to provide health-related data, if not guidance on personal exposure measurements. Another question they tried to address was how to meet the power requirements of a remote sampling system in the absence of a reliable supply of electricity. The second half of the day was devoted to identifying a framework for the next steps and preparing a detailed outline for a guiding document.
