About Aerosan

More than a toilet.  
A city system.

Aerosan is Nepal's first smart, self-sustaining public sanitation enterprise — designed for gender equity, environmental regeneration, and financial independence from day one.


We build IoT-monitored HUBs that convert waste into biogas and organic fertilizer, operated by trained local cooperatives, with dedicated menstrual hygiene and disability-accessible infrastructure in every unit.

Gender & MHM Inclusive Design

Dedicated female sections, menstrual hygiene bins, sanitary dispensers, and safety lighting in every HUB.

Circular Economy Integration

100% waste converted to biogas energy and certified organic fertilizer — nothing reaches rivers.

Real-Time IoT Monitoring

Live dashboards track cleanliness, occupancy, energy production, and maintenance needs 24/7.

What We Build

Six pillars of the Aerosan system

Each HUB integrates smart technology, human equity, and circular economics into a single cohesive platform.

  • ✓ Zero govt dependency
  • ✓ Biogas & fertilizer sales
  • ✓ Bio-Cafe
  • ✓ Sales
The Circular System

Waste in. Value out.

Every gram of waste that enters an Aerosan HUB exits as energy, fertilizer, or community income. Nothing reaches the river.

🚽
Step Step 01

Onsite Waste Storage

Sealed hygienic chambers capture all waste- no drains, no river contact and no contamination

🧫
Step Step 02

Bio-Digestion

Anaerobic micro-organisms break down organic matter in sealed digester tanks, producing methane and nutrient-rich effluent

⚡
Step Step 03

Energry Production

Biogas powers on-site cooking, Processed effluent becomes organic fertilizer which will be sold to local farms

🌱
Step Step 04

Community Reinvestment

Revenue funds operator wages, maintenance, and new HUB expansion — a fully self-sustaining loop.

What people say

Thank yoy for the biogas coffee. I have visited many public toilets, but have never seen a biogas cafe before. I think it is an interesting innovation to reuse biogas from the sanitation facility to provide customers with refreshments. Best wishes and good luck in future.

Thank you very much for showing me around this public toilet facility. I have visited many such facilities around the world and am very impressed with this one in terms of design, cleanliness, and management arrangements. I hope to see more public toilets in Kathmandu and elsewhere in future.  With best regards and good luck with this social enterprise.
