SF#05 Clean clay brick firing technology: Habla Zig-Zag Kiln


Sustainability Factsheet #04

Habla Zig Zag Kilns (HZZKs) offer an innovative and scalable kiln that is versatile and can be configured for either large or small commercial use.  

The kiln provides a unique, energy efficient, low-emission technology with significant social, environmental and economic benefits. High temperatures and turbulent zig-zag air-flow in a long fire zone results in almost 100% fuel combustion. A critical benefit is that the volume can be scaled up or down to suit demand.
