“…Faecal sludge from ventilated improved pit latrines was dried in a convective drying thermobalance by varying the temperature from 40 °C to 80 °C, resulting in a drying rate ranging between 1 and 40 g/ min/m 2 and a moisture content of dried products ranging between 2.4 and 3.2 g/g db (Pocock et al, 2022). Seodigeng et al (2022) dried human faeces using solar and wind energy under ambient conditions and further developed thin-layer drying semiempirical models. Venkata Sai and Reddy (2022) proposed a solar energy drying system of BW treatment with a BW capacity of 2.4 kg/day in which the moisture content of BW was reduced from 70% (w.b.)…”

Nutrient recovery and recycling are of great importance in sustainable development. Blackwater (BW) refers to wastewater from toilets, which contains feces, urine, water, and toilet paper from flush toilets. The highly concentrated nutrients of blackwater could be collected through source separation and treated adequately to recover nutrients efficiently and economically. The review intends to give an overview of the characteristics of BW and different techniques to recover nutrients and other valuable products. A number of these technologies are currently under development or being tested at laboratory or pilot scale. The perspective for blackwater nutrient recovery technologies is very positive due to their great potential. For application of source-oriented sanitation infrastructure and systems, there is still a long way to go for development of commercial technologies and valuable products.
