Charleston, the largest city in South Carolina, has banned plastic bags, straws and foam containers, joining the 10 other coastal communities that have already enacted similar bans over the past three years.

City staff conducted surveys this year and in 2017 to gauge support among businesses and residents for a ban, and both showed roughly 99 percent of respondents were in favor of it.

While the city’s ordinance is now official, businesses will have until Jan. 1, 2020, to discontinue their use of straws and plastic and foam containers, and they have an option of extending the deadline another year if needed.
