On-site sanitation is the most popular sanitation option for households in many African countries, including Ethiopia. Despite the option being common, there are challenges attributed to the sustainability of those facilities. This community-based exploratory study aimed to explore the challenges in the provision of safe urban on-site sanitation in Jimma town, Ethiopia. Data were collected through key informant semi-structured interviews, transit walks through the village, and focus group discussion (FGD). The FGD was audio recorded and notes were taken by experts. Records and notes were transcribed separately and thematically analyzed. Three major themes or challenges were discovered. Accordingly, the first theme was the community’s perception and taboos surrounding human waste. The second theme was urban land use and informal settlements. Ensuring standards separately for sanitation facilities is difficult because of the expansion of illegal settlements. The third theme was poor sanitation planning, operation and maintenance, and institutional setting. Urbanization without infrastructure generally has a complex nature that leads to a fragile sanitation situation in the future. The results suggest the need for multi-dimensional system development and a collaborative sanitation master plan. Furthermore, interventions aimed at breaking the taboo on human waste as a sanitation platform may turn challenges into opportunities.

“…Human excreta is mostly composed of water. Feces water content is a factor of health status, the quantity of water taken in, and the duration the feces spend in the intestine before it is excreted [32,33]. Fresh human feces contain 75-80% moisture content, while the rest are solids (ash, undigested fats, food remnants, and proteins).…”

“…Fresh human feces contain 75-80% moisture content, while the rest are solids (ash, undigested fats, food remnants, and proteins). The pH of feces is approximately 5-7 [34], and urine contains approximately 90% water, with the rest being inorganic salts, organic compounds, organic ammonium salts, and urea [35]. An individual excretes approximately 50 kg of feces and 500 kg of urine each year with the following composition: 1.2 kg K, 0.6 kg P, and 5.7 kg N, but only 60-65% of total P, 50-80% of total K, and 90% of total N are excreted in the urine [36].…”

“…The characteristics of urine are affected by the quantity of water taken in, the organism's body size and feeding habits, the source of the urine, and the well-being of the microorganisms that excrete the urine. Urine is made up of organic compounds (primarily creatine, uric acid, and creatinine) and inorganic compounds (primarily nitrogen, potassium, and phosphorus) [34]. The percentage concentration of the critical elements in urine mainly determines the various components of urine.…”

“…Urine is reported to typically contain 1 g and 9.1 g of phosphorus and nitrogen per litre, respectively. The high composition of nutrients in unadulterated urine enables the development of more efficient energy-recovery techniques and practical nutrient-recovery concepts [34]. The developed nutrient recovery concept will help mitigate the environmental degradation that nutrients (potassium, phosphorus, and nitrogen) are likely to cause.…”

Human and animal waste, including waste products originating from human or animal digestive systems such as urine, feces, and animal manure, have constituted a nuisance to the environment. Inappropriate disposal and poor sanitation of human and animal waste often cause negative impacts on human health through contamination of the terrestrial environment, soil, and water bodies. Therefore, it is necessary to convert these wastes into useful resources to mitigate their adverse environmental effect. The present study provides an overview and research progress of different thermochemical and biological conversion pathways for the transformation of human- and animal-derived waste into valuable resources. The physicochemical properties of human and animal waste are meticulously discussed as well as nutrient recovery strategies. In addition, a bibliometric analysis is provided to identify the trends in research and knowledge gaps. The results reveal that the U.S.A, China and England are the dominant countries in the research areas related to resource recovery from human or animal waste. In addition, researchers from the University of Illinois, the University of California Davis, the Chinese Academy of Science and Zhejiang University are front runners in research related to these areas. Future research should be centred on developing technologies for the on-site recovery of resources, exploring integrated resource recovery pathways, and exploring different safe waste processing methods.
