Special Issue Information

Dear Colleagues,

Membrane technologies have played a crucial role in achieving sustainable resource recovery. As environmental issues arise, the need for efficient, cost-effective, and eco-friendly solutions to retrieve valuable resources from waste streams becomes ever more urgent. This Special Issue on "Advancements in Membrane Technologies for Resource Recovery" aims to collect the latest findings and research progress in this field, emphasizing the role of membranes in achieving sustainable development goals. The primary objective of this Special Issue is to provide a comprehensive platform for researchers, engineers, and institutions to present their work and ideas on novel membrane technologies designed for resource recovery. This issue will explore the advancements in membrane material science, process engineering, and applications across various industries. It seeks to highlight the versatility and potential of membrane technologies in recovering water, nutrients, energy, and other valuable resources from different waste streams. This Special Issue will serve as an essential reference for scientists and engineers working in the field of membrane technologies and resource recovery. By compiling high-quality research articles, reviews, and case studies, it expects to advance the understanding and application of membrane technologies in resource recovery, promoting the development of sustainable solutions to address global environmental challenges. The Special Issue will cover a broad range of topics, including, but not limited to, the following:

  • New membrane materials for resource recovery;
  • New membrane processes for resource recovery;
  • Green fabrication techniques;
  • Hybrid systems and integrated approaches;
  • Economic and environmental impacts;
  • The recovery of different resources, such as water, salt, ions, energy, and heat.;

This study explored the batch membrane filtration of 40% ethanol extracts from spent lavender, containing valuable compounds like rosmarinic acid, caffeic acid, and luteolin, using a polyamide-urea thin film composite X201 membrane. Conducted at room temperature and 20 bar transmembrane pressure, the process demonstrated high efficiency, with rejection rates exceeding 98% for global antioxidant activity and 93–100% for absolute concentrations of the target components. During concentration, the permeate flux declined from 2.43 to 1.24 L·m−2·h−1 as the permeate-to-retentate-volume ratio increased from 0 to 1. The process resistance, driven by osmotic pressure and concentration polarization, followed a power–law relationship with a power value of 1.20, consistent with prior nanofiltration studies of rosmarinic acid solutions. Notably, no membrane fouling occurred, confirming the method’s scalability without compromising biological activity. The antioxidant activity, assessed via the DPPH method, revealed that the retentate exhibited double the activity of the feed. Antibacterial assays using broth microdilution showed that the retentate inhibited Escherichia coli by 73–96% and Bacillus subtilis by 97–98%, making it the most active fraction. These findings validate the effectiveness of the X201 membrane for concentrating natural antioxidants and antibacterial agents from lavender extract under sustainable operating conditions.
