One viable approach to address this issue involves the implementation of nano-additives into the membrane matrix. In this research, the potential of chamomile leaf nanoparticles (Chm NPs) as an eco-friendly material for use in UF membrane synthesis was explored. To better understand the impact of Chm on the production of PES UF membranes, a range of membranes were created by introducing varying amounts of Chm into the casting solution. The produced membranes were thoroughly evaluated, focusing on aspects such as porosity, pore size, hydrophilicity, membrane morphology, and UF performance. Manufactured PES/Chm membranes demonstrated significantly increased permeate water flux (PWF) (up to 367 L/m<sup>2</sup> h), which was three times that of the pristine PES membrane (126 L/m<sup>2</sup> h). Beside Methylene Blue dye (MB) rejection, it was obtained a high removal percent of about 94 %. Additionally, decreased contact angle (C.A.) for modified membranes (47%), compared with pristine PES membranes, all these results led to enhance the membrane permeate flux and rejection.

Biodiesel generation from macroalgae uses several methods, but this research focuses on base catalysts. The paper begins with a detailed overview of bio-diesel production and its usefulness as an eco-friendly fossil fuel alternative. It then examines macroalgae and their role in biodiesel production. Macroalgae’s abundance, rapid growth, and lack of rivalry with food crops are all discussed in the article. Additionally, it solves extraction efficiency and production cost constraints. The review focuses on alkaline catalysts for macroalgae biodiesel production. The benefits of solid-base catalysts over liquid-base catalysts make them suitable biodiesel catalysts. These benefits include increased process efficiency, catalyst recovery, waste reduction, and environmental impact reduction. Overall, this offers an extensive examination of the process of producing biodiesel from macroalgae with base catalysts.
