Plastic pollution in the ocean has become a serious threat to the health of marine life and even terrestrial life. It is also a challenge to transport it landside for recycling. A system to recycle the plastics in situ on an island was proposed with the aim to convert the plastics to fuel gases, such as H2, CH4, and CO. As one of the most abundant thermoset plastics in the ocean, epoxy plastics were recycled in this system. They were gasified in supercritical water driven by concentrated solar energy. A heat exchanger and turbine were used for electricity. The fuel gas could be stored in the gas tank at 4 MPa. The energy and exergy efficiency in this system were analyzed, and the effects of temperature, pressure, and feedstock concentration were discussed. The typical conditions were as follows: temperature 600 °C; pressure 25 MPa, and feedstock concentration 5 wt %. The mole fractions of these products were 48.13%, 22.97%, 0.84%, and 28.06%, respectively. Additionally, the energy and exergy efficiency were 51.75% and 45.22%, respectively.

“…Figure 5 outlines the differences between conventional and hydrothermal gasification processes. Studies on the gasification of human and animal waste are related to the parametric evaluation of the impact of process conditions on gaseous yield, process optimization [64], energy and exergy analysis [65], kinetics studies [66], and techno-economic and life cycle assessment [67,68]. Some researchers have also focused on developing innovative heterogeneous catalysts for improving product yield and selectivity or co-gasification with other waste materials [69].…”

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.
