Summary

Som resultat af projekterne kan drages følgende hovedkonklusioner om kompostering af fæces fra mennesker: Fæces fra de undersøgte typer af kompostbeholdere bør ikke anvendes til jordbrugsformål uden viderebehandling, da dette skønnes at være behæftet med hygiejne- og sundhedsrisici. Det skyldes, at der ikke blev dokumenteret egentlige termofile temperaturstigninger i fæcesmaterialet i komposttoiletenhederne i Hjortshøj, Dyssekilde og Sverige, og at fækale indikatorbakteriers antal varierede voldsomt, og der ingen entydig tendens var til forekomst af lavere kimtal ved lange opbevaringstider af de opsamlede fækalier.

Summary translation

The following main conclusions can be made as a result of the investigation on composting of human feces: Feces from the investigated compost containers should not be used for agricultural purposes, e.g. in the garden of the owner of the compost toilet without additional treatment as such usage will be associated with sanitation and health risks. This is due to the following: No thermophilic temperature development was registered in the composted fecal material in compost toilet containers in Hjortshøj, Dyssekilde, and Sweden. There were large variations in numbers of fecal indicator bacteria and no clear association between lower bacterial counts and prolonged storage time periods of collected fecal matter.
