Cow manure is about to become the unsung hero in the fight against pollution, greenhouse gases, and waste management issues. This stinky substance is being transformed into a versatile and eco-friendly cellulose, which has a wide range of applications in industries such as food, pharmaceuticals, and textiles.

As it decomposes, cow manure releases greenhouse gases like methane, carbon dioxide, and nitrous oxide that are major contributors to climate change. Manure can also contaminate water sources and the air, spreading disease-causing pathogens.

Traditionally, cellulose is extracted from plants and trees, but the process usually involves harsh chemicals and a lot of energy. This ends up hurting the environment. However, a new method developed by researchers at the University College London (UCL) in their research findings published in “The Journal of Cleaner Production” is energy-efficient.

The researchers reported that the cellulose fibers produced from cow manure were extremely fine, only about 13 nanometers in diameter—smaller than human hair.  Such nanocellulose boasts impressive qualities, including high strength, flexibility, biodegradability, and safety for various applications. Its strength and stiffness are comparable to steel, making it ideal for reinforcing materials in composites, films, and eco-friendly packaging.

It also holds promise in energy storage, biomedical applications, electronics, and even food additives. Its large surface area and biodegradability make it ideal for creating environmentally friendly alternatives to plastic packaging, enhancing durability without sacrificing sustainability.
