Stage 4: Transition to Scale

We launched the first AerosanHUB pilot & plan to expand the model in South Asia. We implement toilet upgrades to improve cleanliness, gender & disabled-inclusive facilities, & treat waste by converting it to energy.

Without proper regulation or management incentives, public toilets in Nepal suffer from inadequate maintenance, unhygienic conditions and disposal of untreated waste into waterways. Women & children are disproportionately affected by a lack of access to sanitary toilets and are most likely to "hold on", resulting in urine & pathogen retention, bladder distension and continence problems. Lack of toilet access also increases diarrheal disease, exacerbating nutritional deficiencies.



We enable existing public toilet operators to enhance their profitability in a way that streamlines with socio-environmental objectives. For example, a biogas plant is constructed that converts toilet waste into energy - benefiting the environment while generating additional revenue. By adopting our model, public toilet operators are motivated to offer services that are gender-inclusive & hygienic. Successful businesses can scale, improving toilet access to the public.

Target Beneficiaries

We help improve the lives of toilet operators (marginalized group) and the general public in urban areas (especially women). Our pilot toilet facility serves between 1- 2000 people a day (730,000/year). Many toilet users are on low to middle incomes such as migrant workers, street vendors, taxi drivers and other people that use public transportation. Baseline surveys show only up to 15% of toilet users are women- likely due to the bad condition of the toilets (demand is high).

Mission and Vision

Sanitation in developing countries is undergoing a crisis, which is exacerbated by population increase, urbanization and the threats of climate change. Sanitation is costly, the work involved in not glamorous and infrastructure is an expensive burden to the government. We aim to change the game of the sanitation industry, by setting the stage for profitable and dignifying work in the sanitation industry that can achieve social and environmental sustainability.

Innovation Description

AEROSAN specializes in adapting technological, business, and policy solutions to challenges in the sanitation industry. We work with toilet operators, local NGOs, marginalized groups, and local governments to adopt a social public toilet business model with 1- an improved design for women & children 2-a biogas plant that converts the waste into energy 3- bundle services (sale of sanitary napkins) to increase profit 4- an evidence-based cleaning compliance program.

Competitive Advantage

AEROSAN has been working with local partners to improve urban sanitation in Nepal since 2015. We developed comprehensive local market intelligence in the public toilet domain. We are thoroughly engaged with local stakeholders: marginalized groups, media, government, and technological organizations. We have a highly qualified and dedicated interdisciplinary team to carry out multi-sectoral collaborations between local and international stakeholders.

Planned Goals and Milestones
