Habla Kilns | Addressing an Urgent Problem
HZZK can provide measurable environmental, economic, social and health solutions to an industry seeking technology and workplace solutions to its highly damaging Black Carbon and CO2 emissions. (e.g. Brick kilns emit 2.7% of total global emissions annually).
The size of the brick industry in the developing world is vast. There are more than 500,000 antiquated, energy‐inefficient and high‐polluting brick kilns operating.
Urbanization drives brick production and is causing rapid expansion of the industry at approximately 6% annually. Asia is leading this trend. In India a 200-300% increase in demand for bricks is projected by 2030, expanding the current annual 250,000 billion brick production from 180,000 kilns.
The industry produces 1.5 trillion clay bricks p.a. Brick kilns needing replacement operate in Latin America, Africa and Asia where an estimated 87% of the global brick production takes place. There is real urgency to curb this industry’s devastating impacts on air quality, health, agriculture and ecosystems affecting billions of people.
The HZZK is different to all other zig-zag kilns because it is the authentic and fully complete zig-zag kiln as designed, constructed and operated by the inventor of (archless) zig-zag brick kilns, Alois Habla.
This historically successful and innovative design, (previously built and operated 150 kilns) was re-established, tested and re-proven in 2016 as a current, clean brick-firing technology.
Other zig-zag kilns in developing countries do not contain the different, unique and critical features of HZZK design, component parts and operation which achieve proven and unsurpassed fuel savings and emissions results.
HZZK is the most energy efficient brick kiln technology yet invented.
Fuel savings achieved in the HZZK quickly repay construction costs. There is a fast payback period, along with additional health, workplace and emissions benefits, as compared to other kilns.
The HZZK is a scalable kiln, which can be quickly constructed for village or industrial settings and ‘kiln clusters’.
Targeted roll-out of the HZZK can curb brick-sector pollution and bring positive social and commercial advantage to the brick industry in the developing world.
HZZK offers a compelling solution for the urgent mitigation of the destructive atmospheric pollution from hundreds of thousands of brick kilns in the developing world.
The Climate and Clean Air Coalition (CCAC) said in October 2017, that the HZZK ‘results in the lowest CO2 emissions of any kiln on the marked it has close to 100% fuel combustion and is an outstanding clean brick firing technology because it is a model that can be replicated throughout the developing world to curb brick-sector air pollution and greenhouse gases.’
HZZK is ready for climate action and roll-out in developing countries.
Kilns are high emitters of greenhouse gases (GHG), CO2, and short lived climate pollutants (SLCP’S) particularly black carbon. Emissions from as many as 500,000 kilns contribute to climate change and severely contaminate air quality, kiln sites, health and agriculture in local, regional and rural communities.
The innovative HZZK design and operation achieves high temperatures using specific internal components and a controlled turbulent, zig-zag air-flow in a long, and moving fire zone. Kiln operation results in almost 100% fuel combustion as well as significantly decreased fuel consumption (from any fuel source). Due HZZK’s high temperatures and combustion there are minimal emissions and significant fuel savings and cost benefits.
Fuel savings achieved in operating the HZZK can quickly repay construction costs with a fast pay-back period, health, workplace and emissions benefits compared to all other kilns.
The unique and independently monitored HZZK project demonstrated
- a clear reduction of CO2, short lived climate pollutants (SLCP’s) black carbon and particulate emissions;
- increased energy-efficiency;
- produced consistent “A” quality bricks;
- significantly reduced brick wastage;
- improved working conditions.
The design and work practices of the HZZK significantly improve working conditions, safety, health and air quality at kiln sites and within local communities.
HZZK aims to promote the dignity, safety and wellbeing of workers and accompanying families.
The brick industry of the developing world is largely unregulated. It is an enormous, expanding industry predominantly of poor workers. Many migrate with families to work in frequently unsafe brick works for the “dry season”. India alone employs 15 million workers.
There are many millions of people working in slavery as bonded labour. Child labour is prevalent in the industry.
Working conditions are commonly harsh, unsafe and contaminated by soot (black carbon) from billowing chimneys where fuel combustion is incomplete.
The majority of the workers toil daily in heavy manual labour and live at sites adjoining kilns where living conditions are rudimentary and frequently lack clean water or any sanitation.
