A Review of Thermochemical Conversion of Waste Biomass to Biofuels

“…The major products are gases and bio-oil with minimal biochar formation. Generally, flash pyrolysis produces approximately 60 -75 wt.% bio-oil, 10 -25 wt.% biochar and 10-30 wt.% gases [41]. Several studies have reported the pyrolysis of human and animal waste for biochar and bio-oil production [42][43][44][45].…”

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.

“…This energy is an excellent option for reducing carbon dioxide emissions that are directly released into the atmosphere and have significant environmental effects such as air pollution. Additionally, biomass energy helps lessen the amount of garbage sent to landfills [119]. Organic material, such as food waste, can be converted into energy instead of being thrown away.…”

Renewable energy (RE) is a field in which an increasing number of academic studies are being conducted on multiple dimensions, including technical, economic, political, and social. Wide and varied disciplines conduct research on the processes of making an investment decision in renewable energy, developing, and adopting policies for this purpose, selecting RE suitable for the location, establishing it by taking economic and environmental factors into account, developing energy distribution and storage systems, and supporting regional development. To accurately calculate the installation costs, which are viewed as one of the barriers to a greater use of renewable energy, the co-benefits of RE must be analyzed and transferred to this calculation, and thus to the decision-making processes. Understanding these co-benefits will also facilitate consumer adoption of sustainable energy sources. In addition to economic growth, financial development, employment growth, and regional development, it is crucial to understand the public health benefits of renewable energy. Through bibliometric analysis, which permits the quantification and visualization of qualitative data, the status and development of the literature on the health benefits of RE are examined in this study. The study determined the most researched topics, current issues and trends, and prominent issues in academic studies. The transition to environmentally friendly energies can be accelerated by increasing public awareness of health co-benefits from a more holistic perspective.
