A report on the waste picked up by cleanup crews working along the nation’s beaches and shorelines from the Surfrider Foundation showed that almost 90% of the more than 80,000 pounds of trash collected in 2020 was plastic. The report also criticizes the use of bioplastics — an umbrella term that refers to plastic alternatives marketed as biodegradable or compostable. Rachel Coccia, plastic pollution coordinator for the foundation, and Holden Hardcastle, chair of the foundation’s San Francisco chapter, talk about beach cleanups during the pandemic and the problems with bioplastics.
