In this second volume, various materials such as Magnetic-based biocomposites, wheat bran/straw-based biomaterials, peel-based biomaterials, luffa Based Biomaterials, composite polymeric membranes, rice husk, hydroxyapatite etc for treating textile waste water are highlighted.   One of the major pollutants in the textiles and fashion sector is textile waste water. Textile wastewater can lead to serious environmental issues if discharged without proper and sufficient treatment. The materials employed along with the technologies available to trate the waste water are the key. There are a lot of advancements in terms materials, technologies employed for textile waste water treatment. Sustainable bio-nano materials and macro molecules play a major role in the efficient textile waste treatment.
