Sponges today are made from plastic, acrylics and antimicrobial pesticides. When used, these materials fray from the sponge and enter our bodies, waterways and oceans. It's one of the ways we're consuming so many micro plastics today. Alternatively, these sponges are made of 100% natural vegetable cellulose and coconut husk. Don't let these kind ingredients fool you though. These babies are durable, and lasts just as long as the traditional sponge. After their use, they can be fully composted instead being incinerated or buried.
