Human excreta is a valuable fertilizer for improving soil quality
and crop productivity, with a potential to replace or complement
the mineral fertilizers. The main challenges related to human
excreta regarding agricultural applications are microbial
contamination risks, loss of nutrients, and odor issues.
Fertilization by lacto-fermented faeces supplemented by biochar has
benefits such as improved soil bulk density, nitrate and potassium
concentrations as well as the yield and yield components of corn,
compared to untreated, simple stored faeces, urine, cattle manure,
and unfertilized controls. Even though the mineral fertilizer
produced corn with significantly higher height and leaf length, it
did not add significantly higher yields than lacto-fermented faeces
supplemented by biochar. A faeces treatment process by combined
lacto-fermentation with thermophilic composting and biochar
supplementation had better reduction of coliforms, Escherichia
coli, Enterococcus faecalis and Clostridium perfringens, and higher
germination of radish and growth of tomatoes than combined
lacto-fermentation with vermicomposting. Urine lacto-fermentation
contributed to a pH reduction below 4, a decrease in the ammonium
concentration and odor strength, as well as an increase in the
germination rates compared to untreated stored urine. The results
of this study provide important information that can set the basis
for scaling up a sustainable technology for the treatment of source
separated human excreta while improving its potential for resource
recovery.
