More than 1.3 million plastic bottles were removed from beaches, rivers and waterways during the world’s largest single-day volunteer ocean cleanup in 2025, highlighting the scale of disposable plastic pollution entering the environment.
About 630,000 volunteers participated in the International Coastal Cleanup, collecting nearly 13.9 million pieces of trash across more than 15,000 miles of coastline and waterways. Plastic bottles were the most frequently recorded item, followed by more than 1.2 million cigarette butts and 885,000 plastic bottle caps.
The cleanup is organized annually by the nonprofit Ocean Conservancy. Dr. Anja Brandon, the organization’s director of plastics policy, said the prevalence of bottles points to both excessive plastic production and failures in waste management. She argued that expanding recycling access, including bottle deposit programs, along with reuse and refill systems could significantly reduce plastic reaching the ocean.
The findings come as governments introduce measures aimed at reducing single-use plastics, although disposable products remain widespread. In the UK, consumers use an estimated 13 billion plastic drinks bottles each year, with roughly half recycled, according to the WWF. A deposit return scheme for drinks containers is expected to begin in 2027, following similar programs in countries including Germany, Sweden and Ireland.
The consequences extend beyond litter on shorelines. Allison Schutes, Ocean Conservancy’s senior director of conservation cleanups, pointed to research documenting the threat plastic poses to marine animals. She said an albatross was recently found to have died after ingesting an entire plastic bottle.
Ocean Conservancy’s cleanup program began 40 years ago, when 2,800 volunteers collected trash along the Texas Gulf Coast. Since then, nearly 19.7 million people across 166 countries and territories have removed more than 439 million items, with a combined weight of about 184,000 tonnes.
The organization says its cleanup data has been cited in nearly 300 peer-reviewed studies and used to evaluate plastic-reduction policies. Research published in 2025 found that plastic bag bans and charges reduced bags as a share of shoreline litter by 25% to 47% compared with locations without such measures.
The latest cleanup figures suggest that reducing ocean plastic will require more than removing waste after it reaches waterways. Cutting single-use plastic production, improving collection and recycling systems, and expanding reuse programs could be critical to preventing the same waste from reaching beaches and oceans in the first place.
