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

Home: Bienvenido

Our Mission

Our mission is to offer a user-friendly, multi-story buildings-oriented structure, with on-site or within close proximity compostation system, which can be duplicated and replace our problematic systems with a sustainable, resourceful & economical, eco-friendly system.

The Challenge

Home: Titular

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

Waste of organic matter

Over half of the global excess organic matter comes from cities, but is treated as waste to be disposed of rather than as an asset for creating biomass.

The global organic excess material surpasses

2.6 million tonnes a day, or

960 million tonnes a year, of which about 500 million tonnes are from urban areas.


These organic materials are

  • human excreta -feces & Urine

  • food residue including liquids,

  • plant-based dry matter.


This excess organic matter is usually regarded as waste material to be disposed of.


Even in environment-oriented areas, excreta is disposed of through sewage systems, and the collection of the rest of the organic matter which is often effort-demanding, energy-consuming, and inefficient, results in the compostation of relatively low amounts.

The impacts of U-ComposTech:

Providing composting solutions for multi-story buildings would address all the above challenges in one go: reduce costs and need for urban sewage systems, save freshwater, as well as generate new biomass – thus allowing cities to re-fertilize the earth.

Our Services

U-Compostech 4 basic corner-stones:

Image by Conscious Design

1. Dry Compostation Technology

Dry Compostation Is a natural, water-free, 4 phases process:

  • Preliminary Mesophilic phase

  • Hot Thermophilic phase

  • Fungal & macroorganisms cooling phase

  • Curing & maturing phase


The end product: Pathogen-free, nutrient-rich, Valuable Compost

2. Domestic, on-site and regional infrastructure

A complete infrastructure setup for multi-story buildings, with user-friendly, no-hassle compostoilets, direct organic matter disposal units, dry organic matter shredding, and accelerated on-site compostation.

3. Minimal Odor and Friction Technology (MOFT)

A septic system using minimal water, friction, and adhesion, which would be integrated with all the domestic units, the maintenance accessories, and the compostation system.

4. Counseling services

Counseling services to municipalities, city planners, architects, and any potential implementers of our systems.
