Over 3 million tons of plastic wastes are abandoned into Oceans each year since 2010.It will take decades or even hundreds years to degrade in sea water! It's time for us to do some contributions to release the pollution burden of the environment.YMO Team have been devoted themselves to apply sustainable materials to eyeglasses manufacturing since 2016. Good news is that YMO produces optical frames/sunglasses which are made of bio degradable acetate called BioAcetate S70.Two production bases of YMO used over 400 tons of bio degradable acetate among total 980 tons acetate consumption between 2017-2024.Compare with traditional acetate cellulose,it can be degraded over 90% within 180 days in organic earth.
