| Zusammenfassung: | © The Author(s) 2015. To evaluate the suitability of biochar (rice husk charcoal) as a matrix in composting toilets that can decompose human faeces and recover fertiliser components, the composting process during toilet operation and the agricultural value of the resulting compost were characterised by performing a comparison with sawdust, rice husks, and corn stalks. The faecal decomposition ratio in biochar was 42%, similar to the values for rice husks (46%) and corn stalks (41%), but higher than the value for sawdust (25%). Heterotroph micro-organism acidity is qualitatively higher in biochar than in sawdust. However, nitrogen loss in biochar was 19%, lower than that in rice husks (36%) and corn stalks (25%), but similar to that in sawdust (16%). Although the biochar compost had no significant impact on the cation exchange capacity and water retention of sandy soil, the ratio of nitrogen transportation into plants was 12.8%, higher than that for the other materials. These results suggest that biochar is effective for achieving high faecal decomposition, low nitrogen loss, and high nutrient supply |
