What recoverable chemical can be obtained from textile mill waste?

The recoverable chemical that can be obtained from textile mill waste is caustic soda, primarily due to the processes involved in textile production. During the textile manufacturing process, significant quantities of sodium hydroxide, commonly known as caustic soda, are used, particularly in processes like dyeing and mercerizing cotton. This chemical is useful for cleaning and treating fabrics, and its recovery from waste can help reduce environmental impact and provide a valuable resource for recycling.

By extracting caustic soda from textile waste, mills can minimize chemical disposal issues while converting waste into a reusable substance. This fits into a broader context of sustainability and waste management practices in the textile industry. Other chemicals listed may not be as directly related to the processes specifically prevalent in textile mills and may not be recoverable from the same waste streams as caustic soda.
