Special Issue Information

Dear Colleagues,

The worldwide crisis of organic solid waste (OSW) generation has caused concerns about a continuous uptrend of natural resource consumption. Anaerobic fermentation (AF), with volatile fatty acids (VFAs) as the main product, has been widely used for OSW disposal and energy recovery. However, the efficiency of AF is generally low due to the rate-limiting step of hydrolysis. Therefore, it is necessary to investigate the rational utilization of AF technology. Hydrolysis pretreatment has proven to be a successful approach to improve the solubilization of available substances. There are significant prospects to investigate the advanced technologies for OSW recycling. This Special Issue focuses on the resource recovery from organic solid waste using fermentation and hydrolysis technologies, and we hope that the Special Issue will become a platform for realizing experiences and sharing valuable research findings on the latest trends in advanced technologies for fermentation and hydrolysis of OSW.

Relevant topics include, but are not limited to:

  • Challenges of fermentation and hydrolysis technologies for OSW;
  • Strategies to enhance fermentation;
  • Hydrothermal recycling technologies;
  • Oriented conversion technologies for carbon and nitrogen recovery;
  • Agricultural and forest OSW treatment.

Melanoidins, as macromolecular heterogeneous organic polymers, are produced from the Maillard reaction between amino and carbonyl groups during the thermal hydrolysis pretreatment (THP) of sludge. The brown color and recalcitrance of melanoidins pose a serious threat to wastewater treatment systems, such as invalidating UV disinfection and decreasing the efficiency of anaerobic digestion; thus, they have gradually received much concern in recent years. However, currently the study on THP-origin melanoidins is limited by a lack of reliable extraction and quantification methods. This paper presents a comprehensive review of the physical, chemical, and biological properties of melanoidins from different sources to fill the research gap on THP-origin melanoidins. The adverse effects of melanoidins on the management of wastewater and sludge are discussed, and for the first time, special attention is paid to the potential environmental hazards of THP-origin melanoidins to natural ecosystems. The removal technologies of melanoidins are summarized and compared as well. Finally, the suggested areas that future studies should focus on are provided. This review is dedicated to providing guidance on melanoidin research and management for the better development of the THP industry. Full article
