The Aerosan HUB Model

Infrastructure that
pays for itself.

A systemic approach addressing the root causes of urban sanitation failure — built on circular economics, smart technology, and human dignity.

Problem vs Solution

What's broken. How we fix it.

⚠ The Problem Urban Sanitation Today
  • Less than 30% of public toilets remain functional in Nepal's cities
  • Unsafe, unhygienic conditions that undermine human dignity and public health
  • No menstrual hygiene facilities — women face dangerous conditions monthly
  • No safe, women-accessible sanitation forcing open defecation
✦ Aerosan Solution The HUB Model
  • Smart, IoT-monitored facilities with real-time cleanliness and maintenance alerts
  • Female-dedicated sections with sanitary dispensers, disposal bins, and privacy
  • Menstrual Hygiene Management (MHM) built into design — not added as an afterthought
  • Disabled-accessible stalls, baby-care stations, and enhanced safety lighting
Core Pillars

Six pillars of every HUB

Technology, equity, and circular economics integrated into one self-sustaining platform.

Hygienic Smart Facilities 01

Hygienic Smart Facilities

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

Menstrual Hygiene Management 02

Menstrual Hygiene Management

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

Gender & Disability Inclusive 03

Gender & Disability Inclusive

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

Waste-to-Energy Technology 04

Waste-to-Energy Technology

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

Employment Opportunities to Female Sanitation Workers 05

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.

Revenue-Generating System 06

Revenue-Generating System

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

Financial Architecture

Five revenue streams. Zero subsidies.

Each income stream is independent — combined they create a durable surplus that funds expansion.

Revenue Model
Revenue streams

Biogas Energy Sales
65%
Organic Fertilizer

Cafe Sales

On-site Advertising
34%
Training Licensing

* Percentages indicate contribution to operational cost coverage per HUB. Combined surplus funds new HUB construction.

"Aerosan HUB is recognized as a best-practice model in urban sanitation innovation — demonstrating that public infrastructure can be both self-sustaining and socially transformative."
