Why Compost?

Open defecation and unhygienic pit-latrines are the standard methods of waste management for millions of people. Yet, these methods are globally among the main routes of transmission for intestinal parasites and other enteric diseases.

The use of compost toilets represents a sanitation solution that fits the rural, agricultural lifestyle of many people without access to other forms of waste management. Agricultural areas are rich in the materials necessary to harness and accelerate this natural process that breaks down pathogens in human waste in the process of creating organic fertilizer.

Our teams are actively converting pit latrines at homes and in schools into compost toilets, instructing the users themselves to build and maintain on-site compost bins (which can be used for kitchen waste and animal manure as well as human feces), and training teachers and community members the scientific and technical basics of a compost-based sanitation system.


  • Prove to a community that mismanagement of human waste is directly related to high rates of intestinal parasites and other enteric diseases by performing on-the-ground, independent testing
  • Thoroughly train compost-toilet users the basic science, protocol, and proper techniques of compost-based sanitation 
  • Use local materials, local labor, and local ingenuity to make compost toilets replicable throughout each community


  • Adoption of compost-based sanitation by 80% of a community’s households and 100% of a community's schools in less than five years
  • Prevalence of intestinal parasites to below 25% in less than five years
  • Locally replicable designs and structures
  • Continual production of organic fertilizer at the household and school level after one year
