An Urban, Dry Compostation system for all Organic excess matters with minimal water and zero waste

Urban growth

More than half of the global population lives in cities, and 85% of them rely on centralized sewage systems.

Since 2010 more than 50% of the world's population live in cities, reaching over 4.5 billion people.

​

By 2050, almost 70% of the people are projected to live in urban areas.

Slightly more than 85% use the regular septic sewage system. The rest 14% of city dwellers, as well as about 48% of the world’s population, do not have access to septic sewage and dispose of their excreta directly, either via basic soak-ways, or boreholes, or on the ground.  

Post-treatment t of the rest of the human organic excess materials is in many cases land & energy-consuming, complex, and inefficient. 

Centralized sewage

Urban sewage systems consume 35% of domestic freshwater, require frequent renovations, and costly landfills, &  are pollutant and counter-sustainable.

Both the sewage system and direct disposal ways are problematic:

The septic sewage system is expensive, health-hazardous, and wasteful, since it:

• Consumes about 35% of domestic freshwater

• Requires costly, renovation every 25-30 yrs. 

• Requires expensive real estate for landfills every 20 yrs. 

• Leaks to the earth, causing ground pollution and freshwater Contamination, therefore is health hazardous

The soak-ways, boreholes, and direct ground disposal, are less water consuming, but cause pathogenic ground pollution and freshwater Contamination, and are health hazards too.

"Every year water and sanitation problems cause more deaths than war and the lack of sanitation is the world’s biggest cause of disease". (UNICEF)  

Water scarcity and pollution

Half the global population faces periods of water scarcity, yet sewage systems not only use much water but also regularly contaminate remaining water sources.

Global scarcity of freshwater:

• 4 billion people, experience severe water scarcity, at least one month a year (UNICEF)  

• Over 2 billion people live in countries where water supply is inadequate (UNICEF)  

• By 2025, 1.8 billion people will experience absolute water scarcity, and 2/3 will be living under water-stressed conditions the world counts

Pollution:                                            "…nearly 50 % of the world’s urban population depends on underground water sources, … more and more aquifers are being polluted, overexploited, and dried up by humans, sometimes with irreversible consequences"  UN World Water Development Report  March 2022 (WWDR). 

"There will be no water by 2040 if we keep doing what we're doing today" Prof.  Benjamin Sovacool, Aarhus University, Denmark.

Soil degradation & desertification

Due to ongoing loss of biomass, the amount of fertile land by 2050 is expected to shrink to only 10% of the Earth.

There is a global ongoing degradation of soil productivity in

 20% of all cultivated areas.

 30% of all forests.

 10% of all grasslands.

• Over 4 million square kilometers are being degraded every year

• 120000 square kilometers are turning into actual desert

• Forecast: By 2050, Food Production Must double, to Meet World’s Growing population, yet only 10% of the earth will be available for growing crops. 

The main reason:  loss of biomass = organic matter
