Why is HZZK Different from Other Zig Zag Kiln Technologies?

• Efficient use of fuel reducing energy consumption, using high, controlled temperatures.
• The movement of the fire through stationary bricks, using less energy. As opposed to, the tunnel kiln, which uses energy to move bricks through a stationary fire zone.
• Efficient firing process through the use of a long fire zone, rapid airflow and unique components.
• The excellent control of the fire and the low brick setting height. HZZK is ideally suited to fire perforated bricks and thin-walled hollow large clay blocks. This conserves topsoil, minimises land degradation and reduces energy requirements for the production of bricks and clay products.
• Almost complete combustion due to high, controlled temperatures.
• Efficient use of generated heat, which is recycled in a continuous process, using a unique heat recovery process.
• Significant efficiencies in drying and cooling of bricks.
• Small construction footprint that can be quickly built with less masonry.
• Long fire zone enabling almost complete fuel combustion and fuel efficiency.
• Roof – offering significant workforce and economic benefits.
• No tall chimney – minimising fuel wastage and workplace pollution.
• Scalable operating modes either continuous or semi-continuous.
• Power source flexibility.
• Easily mechanized technology.

The HZZK Difference: a Positive Impact on Workers

• Improves health outcomes of all workers and communities.
• Promotes safe, sustainable work practices and the dignity of all workers.
• Uses and upgrades skills of existing workforce whilst maintaining employment.
• Significantly reduces GHG emissions, CO₂ and short-lived climate pollutants (SLCP’s) particularly Black Carbon (soot).
• Improves agricultural outcomes, locally and regionally.

A Key HZZK Difference: Improved Economics

• Significant fuel savings, increase profits.
• Production of consistent, quality, saleable bricks increases profits.
• Construction costs are lower.
• Maintenance costs are lower.
• The payback period is short.
• Carbon credit generation is possible.
• Reduces annual foreign exchange expenditure on imported coal for brick firing. Nepal spends a reported US$153.7 million p.a on coal.
