Special Issue Information

Dear Colleagues,

We invite you to contribute to this Special Issue, entitled “Biomass Conversion and Organic Waste Utilization in Wastewater”, where we will publish papers discussing new techniques and methods for biomass conversion and organic waste utilization in wastewater areas, as well as new discoveries about the mechanisms and means of controlling of this process. This Special Issue will serve as a platform for cutting-edge articles and an updated forum for scientists to exchange knowledge and ideas.The concept of the circular economy has gained significant global traction in the past decade because it emphasizes sustainable development principles. As a result, it is crucial to shift from end-of-pipe approaches to integrated resource recovery, changing the perception of waste streams from sources of pollution to valuable resource pools. The management of high-concentration organic wastewater is a significant global issue, and its mishandling will lead to substantial environmental problems. However, this type of wastewater also has considerable potential within the circular economy, as it can extract various scarce resources such as water, energy, biofuels, fertilizers, and biopolymers. It is important to note that most current research primarily focuses on improving the removal efficiency of pollutants in high-concentration organic wastewater treatment, neglecting resource recovery. Therefore, wastewater treatment should prioritize the development of technologies that not only ensure adequate treatment of high-concentration organic wastewater but also enable resource recovery throughout the treatment process.

Based on the life cycle assessment methodology, this study systematically analyzes the energy utilization of environmental waste through photocatalytic treatment and simultaneous hydrogen production. Using 10,000 tons of organic wastewater as the functional unit, the study evaluates the material consumption, energy utilization, and environmental impact potential of the photocatalytic waste synchronous hydrogen production system (specifically, the synchronous hydrogen production process of 4-NP wastewater with CDs/CdS/CNU). The findings indicate that potential environmental impacts from the photochemical treatment of environmental waste and synchronous hydrogen production primarily manifest in freshwater ecological toxicity, marine ecological toxicity, terrestrial ecological toxicity, and non-carcinogenic toxicity to humans. These ecological impacts stem from the catalyst’s adsorption and metal leaching during the photo-degradation and hydrogen production processes of environmental waste. By implementing reasonable modifications and morphological refinements to the catalyst, these effects can be mitigated while achieving enhanced efficiency in environmental waste processing and simultaneous hydrogen production. The research outcomes provide valuable insights for advancing sustainable development in green technology for environmental waste treatment and energy utilization. Full article
