Abstract

Abstract: In this paper, two brick kiln technologies—the Bull's Trench Kiln (BTK) and the Induced Draft Zigzag Kiln (ZZK)—were compared through a transdisciplinary approach by focusing on two questions: do ZZKs tend to be cleaner than BTKs? Will operating ZZKs generate any reasonable economic and social benefits? To answer the first question, stack emission samples were collected and tested from two kilns: a newly constructed ZZK in Punjab, Pakistan and a conventional BTK located close to the ZZK. To address the second question, a cost-benefit analysis of the two types of kiln technologies was conducted using primary data on input and output quantities and prices from the sample kilns. The environmental results show that the ZZK emitted significantly less amount of harmful gases and particulate matter compared to the BTK. The economic analysis demonstrates that ZZKs improve both private and social welfare in monetary terms compared to BTKs. Our findings provide a case for the adoption of ZZKs in developing countries and for environmental policymakers to facilitate the technology transition.
