"Toilet" and the sanitation system that supports it will cause damage to the environment, health, and even the economy in the case of insufficient funds or poor management, especially in the poorest and most marginalized places. The harsh sanitary environment will pollute water and land, indirectly affect people's livelihood water resources, and the primary industry, and spread deadly diseases among the population.

Climate change is increasing, and floods, droughts, and rising sea levels are threatening sanitary systems, including toilets, septic tanks, and sewage treatment plants. For every $100 invested in basic sanitation facilities, it can save five times more medical expenses and create jobs in the service chain. For women and girls, toilets set up in families, schools and workplaces help them to give their potential full play and contribute to society, especially during menstruation and pregnancy.

Although access to clean water and sanitation has greatly increased in modern times, billions of people are still lacking these fundamental infrastructures; one-third of the world's population does not have access to safe drinking water, two-fifths of the population lacks basic hands cleaning resources, and even more than 679 million people are still defecating outside toilets.

One of the United Nations Sustainable Development Goals (SDGs) is to achieve "adequate and equitable " sanitary and hygiene conditions for everyone by 2030. Improving toilets will reduce diseases and double the protection of public health and women's safety. It is an important indicator of community health and women's rights and interests.

Work abstract

  • School and community bio-toilet establishments and  Excreta treatment promotion.
  • Make training manuals and publicize them to the community.


We are looking for affordable and easy-to-acquire building materials locally, and hiring local personnel to convey knowledge and techniques, so that buildings can be imitated and easy to maintain. Bio-toilets do not need to flush with water, which is suitable for remote villages with scarce water sources. We only need to change collection buckets and save the use of land.

Build bio-toilets for schools and community centers to amplify the influence. By using bio-toilets in public areas, the surrounding communities can be more familiar with them and implement them in their household.

Can you imagine?

People use toilets every day, but there are many people who only have dirty and smelly pits or toilets. In the wild, defecation may be attacked by animals, and the excreta cannot be properly handled, which is easy to pollute the land and water, which is even more deadly. Bio-toilets can not only save resources but also turn excreta into composting and nourish the crops in the field. Having a good toilet can protect the health and quality of life of women and children.
