Anaerobic digestion for organic waste generated in textile production value chain

Anaerobic digestion, also called biomethanation, is a process by which organic matter are digested and synthesised by select bacteria to produce biogas, a fuel that is a mixture of methane and CO2. This is thus an avenue to convert many types of solid and liquid organic waste into a valuable product. 

 

The textile industry also has opportunities to use anaerobic digestion for some of its waste streams.

How does it work?

Anaerobic digestion is a process by which organic matter such as animal or food waste is broken down to produce biogas and biofertilizer. This process happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester.

Sustainability benefits

Anaerobic digestion systems convert waste that would have otherwise entered the landfill or wastewater streams into valuable fuels, thus providing a sustainable avenue for waste disposal. Recovery of biogas also reduces the overall carbon footprint of the operations

Highlights/USP

While the most obvious use of anaerobic digestion will be for the wastewater sludge streams generated during textile processing, interesting possibilities also exist for using this to convert agricultural wastes generated during fiber cultivation (cotton stalks for instance) into biogas.

Production of biogas from textile sludge by anaerobic digestion

The anaerobic treatment is termed to have produced biogas (methane and carbon-di-oxide) which if harnessed can be used as fuel. Biogas from textile sludge than can be used as household cooking, car fuel & can produce electricity with the help of gas generators. This article gives a detailed analysis on how anaerobic digestion can be used for the production of methane biogas through textile sludge treatment.

Treatment of textile sludge using anaerobic technology

The anaerobic treatment not only treats textile sludge, it was also found to have an additional benefit of producing biogas (methane and carbon (IV) oxide) which if harnessed may be used as fuel. This article gives a detailed study of how anaerobic digestion can be used for textile sludge treatment.
