A ban on polystyrene went into effect for small businesses in San Diego in April. Polystyrene is a synthetic polymer sometimes colloquially called Styrofoam, especially in the U.S.
The move means more costs for small businesses in that California community.
“Polystyrene plastic foam is one of the biggest sources of marine litter and costs the state and local governments millions of dollars each year to collect it from beaches, roadsides, and storm drains,” writes Mariel Garza for the Los Angeles Times.
Small businesses making less than $500,000 annually received a brief year-long exemption. But now the cost of eliminating the waste falls on the businesses that can afford it least.
