Take tequila, for example, made using agave. Since only the juice is used, often the rest of the plant is left to decompose in fields. 3Mers from the U.S. and France, looking to manufacture 3M products with more sustainable materials, partnered to create scrubbing fibers made of 50 percent agave. These fibers are the scouring muscle of a plant-based-fiber sponge that uses 23 percent recycled material. It took a lot of work to adapt the material to manufacturing processes, but thanks to their passion and persistence, they were able to create the Scotch-Brite® Greener Clean Non-Scratch Scrub Sponge.
