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.

Infrastructure

Hygienic Smart Facilities

Automated cleaning alerts, touchless fixtures, air-quality sensors, and odor monitoring ensure consistently clean conditions every operating hour.

✓ Touchless fixtures
✓ Scheduled Cleanliness Protocol
✓ Electronic Barriers for safety of users
✓ Human and Darkness detecting sensor lights

Health Equity

Menstrual Hygiene Management

Sanitary vending machines, hygienic disposal bins, privacy screens, and clean changing facilities built into every female section — not afterthoughts.

✓ Sanitary vending
✓ Private changing areas
✓ Hygienic disposal

Universal Design

Gender & Disability Inclusive

Dedicated female sections, full wheelchair access, baby-care stations, and enhanced safety lighting — equitable design as a standard, not an upgrade.

✓ Full wheelchair access
✓ Baby-care stations
✓ Enhanced safety lighting

Circular Economy

Waste-to-Energy Technology

Sealed anaerobic bio-digesters convert 100% of faecal waste into biogas and organic fertilizer. Zero river discharge — guaranteed by design.

✓ Biogas plant
✓ Rain water harvesting
✓ Waste water treatment plant

Smart Operations

Employment Opportunities to Female Sanitation Workers

The women sanitation workers from the marginalized community (Pode, Deula, Pariyar) are provided with dignified job opportunity. Also, the disabled women who could not hear are trained with the protocol of Aerosan and provided job opportunities.

✓ Dignified Job Creation
✓ Marginalized community
✓ Women
✓ Disabled

Financial Model

Revenue-Generating System

User fees, biogas sales, organic fertilizer, advertising, and training licences create a five-stream surplus — no government dependency, ever.

✓ User Tarrif
✓ 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.

Student

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.
