A new technique to extract tiny cellulose strands from cow dung and turn them into manufacturing-grade cellulose, currently used to make everything from surgical masks to food packaging, has been developed by researchers from UCL and Edinburgh Napier University. The study, published in The Journal of Cleaner Production , describes the new ‘pressurised spinning’ innovation and its potential to create cellulose materials more cheaply and cleanly than some current manufacturing methods, using a
