Kazuba™ commercial desiccating dry toilet system

Kazuba™ | STK System

Kazuba™'s higher-use dry toilet system, designed around strong passive airflow and long-term public or commercial operation.

The STK uses an aerodynamic ventilation curve, thermal chimney and wind-driven extraction to support urine evaporation, solids dehydration and zero-effluent operation in suitable outdoor conditions.

Tested use

30+ Uses / Day

Current certified schedule positioning

Solids

Up to 90% Less

Volume reduction through dehydration

Utilities

Passive

No water, chemicals or electrical power in standard operation

Discharge

Zero Effluent

Dry-toilet pathway

High-use dry toilet technology

Built around airflow rather than water or bulking material

The STK separates liquids from solids and uses continuous airflow to drive the drying process.

Urine is evaporated while solids progressively dehydrate and reduce in volume, avoiding the wet-composting pathway used by conventional composting toilets.

How it works

Thermal gain and wind work together

Stage 1 Air enters

Fresh air is drawn through the toilet pedestal and into the dry-toilet system.

Stage 2 Waste dries

Temperature, solar gain and airflow evaporate urine and remove moisture from the solids.

Stage 3 Air extracts

The thermal chimney and wind-driven vent maintain extraction through the system and away from the toilet room.

Core advantages

Designed for public and commercial dry sanitation

Waterless operation.
No bulking agents required.
No routine chemical addition.
Passive solar- and wind-driven ventilation.
Urine evaporation.
Solids dehydration with substantial volume reduction.
Zero-effluent dry-toilet pathway.
Low mechanical complexity.
Suitable for permanent public and commercial projects when correctly specified.

Permanent in-ground installation

STK systems use the permanent Kazuba™ installation pathway. The tank is installed into the ground and integrated with the slab and selected building or pedestal arrangement.

WCTNZ® manages the installation pathway within the agreed project scope.

Good to know before purchase

Drying capacity is climate and site dependent. Strong sun and wind support passive performance.

Where the site is colder, heavily sheltered or has weak wind conditions, WCTNZ® can assess fan-assisted ventilation or temperature compensation as part of the project design.
