Beach clean events at West Sands in St Andrews and at Tentsmuir Point Nature Reserve are included in the Marine Conservation Society (MCS) Great British Beach Clean over the weekend of September 19-22.
MCS hopes to get a record number of people cleaning beaches around the UK, and is looking for volunteers.
Tom Bell, MCS campaigns manager, said: “Our domestic habits over the last 50 years or so have resulted in dirty beaches. We throw more stuff away than ever.
“Plastic in the marine environment may take hundreds of years to break down and it washes up or is blown onto beaches in bits from micro pieces to larger chunks.
“We flush stuff down the loo we shouldn’t, and that ends up in our water ways and then our beaches. We want to see people turning out to clean up their favourite or local beach during our Great British Beach Clean weekend. Please don’t turn your back on our beaches.”
