A microbead ban has been put into Maine law.

The proposal by Sen. Tom Saviello, who represents part of Kennebec and Franklin counties, became law this week.

Microbeads are plastic non-biodegradable bits used in personal care products like toothpaste and facial cleansers.

According to the law, microbeads will have to be phased out in three years before the law fully takes effect in 2019.

Illinois has already passed a microbead ban and Colorado and New Jersey have bills going through their chambers as well. According to reports, many manufacturers have already begun the process to phase out the microbeads from their products.

The environmental issue is microbeads are too small for filters and end up in lakes and rivers.
