WASHKing manufactures, supplies and installs environmentally friendly biodigester toilets. The toilets are built locally by local artisans and using regionally available materials. The WASHKing technology introduces a locally made biodegradable powder developed in India for digestion. In addition, the treatment system separates effluent and turns it into safe water for agriculture or landscaping.

The main target groups are low-income urban households and institutions with poor or no access to toilets. Flexible payment terms, training on hygiene and after-sales services ensure customer loyalty.
