What is the primary focus of using agricultural waste for wastewater treatment?

In wastewater treatment, it is the application of agricultural waste materials such as rice straw, leaf litter, or plant residues to eliminate or treat pollutants in wastewater.

The textile industry is widely recognized as one of the most important drivers of the global economy. However, this industry also releases large amounts of dyes, toxic metals/elements, and chemicals into water systems. It is estimated that over 100,000 different dyes are used in the textile sector. As a result, the textile industry is believed to contribute around 300,000 tons of water pollution annually. These toxins and carcinogens can lead to various health problems, including asthma, allergies, and skin irritation.
