Resumen:
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
USA, 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 Sciences, and Zhejiang
University are front runners in research related to these areas. Future
research could be extended to the development of technologies for
on-site recovery of resources, exploring integrated resource recovery
pathways, and exploring different safe waste processing methods.
