Core horizontal nozzle-pressurized spinning turns cow manure, cheaply and cleanly, into cellulose, one of the world’s most used materials

https://www.eurekalert.org/news-releases/1082848 "no electrospinning with its high voltages/ toxic chemicals... uses pressure/ rotation simultaneously to spin fibers, beads, ribbons, meshes, films (each of which have different manufacturing applications) from soft matter liquid jet, using horizontal rather than vertical vessel containing surface nozzles/ injecting jet into still or flowing water, forming cellulose fibers... existing pressurized spinning machines adapted... work with dairy farmers to scale... cling film, surgical masks, paper products, textiles, foods, pharmaceuticals."

Sustainable hairy cellulose nanocrystals selectively salvage rare earth elements such as neodymium from electronic waste

https://www.psu.edu/news/engineering/story/salvaging-rare-earth-elements-electronic-waste/ "researchers negatively charged the hairy layers of the nanoparticles in order to attract and bind with the positively charged neodymium ions, resulting in particle aggregation into larger pieces that can then be effectively recycled and reused... Using cellulose as the main agent is a sustainable, cost-effective, clean solution"
