Title: RESOURCE RECOVERY AND BIOCHAR CHARACTERISTICS FROM FULL-SCALE FAECAL SLUDGE TREATMENT
Unsafe disposal of faecal sludge from onsite sanitation in low-income countries has detrimental effects on public health and the environment. The production of biochar from faecal sludge offers complete destruction of pathogens and a value-added treatment product. To date, research has been limited to the laboratory. This study published as an article in the 169th Water Research Journal, evaluates the biochars produced from the co-treatment of faecal sludge from septic tanks and agricultural waste at two full-scale treatment plants in India by determining their physical and chemical properties to establish their potential applications. The process yielded macroporous, powdery biochars that can be utilised for soil amendment or energy recovery.
Co-treatment of faecal sludge with other carbon-rich waste streams can be used to inﬂuence desired biochar properties. In this case, the addition of agricultural waste increased nutrient and ﬁxed carbon concentrations, as well as providing an additional source of energy. This study is a proof of concept for biochar production achieving full-scale faecal sludge treatment.
