Worldwide, only 2% of human waste is disposed of safely when there is no service chain. While many people lack access to any type of toilet facility, still more use systems that do not provide any type of treatment for the resulting waste. This untreated waste flows directly into soils and water systems, causing not only environmental damage but also widespread disease.

In response to this crisis, the United Nations established Sustainable Development Goal (SDG) 6.

“Ensure availability and sustainable management of water and sanitation for all.”

Public, private, and citizen-led organisations have taken this challenge head-on, committing time and resources to help the 2.3 billion people in the world without access to safe sanitation.


The modern system of sewer infrastructure cannot solve this problem due to its extremely high demands for water, energy, raw materials, and large-scale coordination.


1. Operate independent of sewer or electric infrastructure
2. Provide users with a comfortable, affordable experience
3. Treat waste so it can be safely disposed
4. Provide options to reuse the system output

This new generation of toilet technologies can surpass the old model of sewer infrastructure to solve problems beyond sanitation. Usable outputs in the form of fertilizers, water, and energy provide resources for communities and create new economic opportunities for communities to build sustainable businesses.

Emerging technologies are utilizing a diverse array of systems and processes, ranging from combustion to composting to electrochemistry.


These new toilet technologies are aspirational, but will they work?

To succeed in changing the world of sanitation and meeting SDG 6, innovators need to show potential users and investors clear, verified evidence that their technologies meet communities’ needs.

This verification comes from applying the International Standards (ISO 30500 and ISO 31800) that TÜV SÜD spearheaded in collaboration with technology leaders, humanitarian organizations, and international government agencies.

TÜV SÜD’s front-line role in coordinating and developing these standards for non-sewered sanitation systems (NSSS) [link to page] and faecal sludge treatment units (FSTU) [link to page] uniquely positions us to guide and support innovators in meeting these standards, achieving certification, and supplying communities with user-friendly, effective, sustainable solutions.
