Special Issue Information

Dear Colleagues,

As the global population continues to grow and urbanize, the production of wastewater has become a significant challenge, posing serious environmental and health risks. The need for sustainable wastewater treatment methods has never been more pressing. Chemical and biochemical technologies offer promising solutions to address this issue efficiently and sustainably. These approaches have the potential to revolutionize wastewater treatment, reduce environmental impact, and contribute to a more sustainable future.

Wastewater treatment plays a crucial role in maintaining the health and integrity of ecosystems and safeguarding public health. However, conventional wastewater treatment methods often fall short in terms of efficiency, cost-effectiveness, and environmental impact. Chemical and biochemical technologies provide alternative and sustainable approaches to address these shortcomings. These technologies utilize various chemical and biological processes to remove pollutants, toxins, and contaminants from wastewater, enabling the generation of reusable water and valuable resources.

The aim of this Special Issue is to showcase cutting-edge research and advances in sustainable wastewater treatment based on chemical and biochemical technologies. By publishing this Special Issue in the journal Sustainability, we aim to bridge the gap between research and practice, promoting the implementation of sustainable wastewater treatment practices in real-world applications.

We invite submissions for papers that explore innovative and advanced treatment methods in the field of sustainable wastewater treatment based on chemical and biochemical technologies. We encourage research on cutting-edge technologies such as membrane processes, advanced oxidation, the utilization of microwaves or ultrasound, selective adsorption on both natural and synthetic materials with enhanced selectivity, biodegradation, and their combinations.

We look forward to receiving your contributions.

As the world transitions towards a more sustainable future, it is imperative to develop innovative solutions that address the pressing issue of plastic pollution. Microplastics, in particular, have become a significant concern due to their widespread presence in the environment and potential to interact with toxic pollutants. Organic compounds, which include a variety of harmful chemicals, such as pesticides and other industrial chemicals, are often released into the environment and can readily bind to microplastics. In this context, understanding the adsorption of organic compounds on microplastics is crucial for designing effective strategies to mitigate their environmental impacts. This study investigates the adsorption dynamics of organochlorine pesticides (OCPs) on polystyrene microplastics, exploring the influence of pH and contact time, as well as utilizing kinetic models and isothermal equations to elucidate the adsorption mechanism. The results suggest that the pH level has a negligible impact on the adsorption capacity of PS for OCPs. In contrast, the contact time plays a significant role in the amount of OCPs adsorbed onto the PS surface. Interestingly, a relatively short time of up to 6 h was sufficient to reach equilibrium. The adsorption of OCPs on PS follows a uniform pattern consistent with the Freundlich isotherm model, indicating a multilayer adsorption process. The use of kinetic models to describe the adsorption process was also found to be useful in understanding its mechanism. Specifically, the pseudo-second-order kinetic model proved to be a suitable descriptor for the adsorption process of organochlorine pesticides on PS. This study highlights the importance of understanding the interactions between microplastics and organic pollutants, which is crucial for developing sustainable solutions to mitigate the environmental impacts of plastic pollution, ultimately contributing to a more environmentally conscious future.
