Hybrid Hoffman Kilns (HHK)

capacity of the VSBK is low compared to 20,000+ from other kiln technologies. Moreover, the VSBK needs to be located on high land above flood level, which is more expensive than low land (Guttikunda and Khaliquzzaman, 2014). Hybrid Hoffman Kilns (HHK) HHK technology is substantially more capital intensive than the kiln technologies discussed above.
