askST: Why is there so much rubbish on the beach in East Coast Park?

East Coast Park had the most flotsam on average during that month at 155.9 tonnes.

The peak is nearly triple the levels it gets in January, when the least flotsam is collected.

Meanwhile, beaches along the northern coast tend to receive more rubbish during the north-east monsoon, which runs from December to March.

A study commissioned by NEA in 2021 found that 97 per cent of the plastic waste on recreational beaches here came from sea-based sources like ships, or were transported across boundaries by marine currents.

Singapore’s battle against marine trash is a joint effort helmed by both volunteers and the authorities.

Non-governmental groups like Stridy and SG Beach Warriors regularly organise beach clean-ups.

In 2022, the Ministry of Sustainability and the Environment launched the national action strategy on marine litter to drive the clean-up of marine litter here.

To ensure that beaches are kept clean during the monsoon months, NEA said the frequency of cleaning operations is increased from four times a week to twice daily.

It noted that despite these intensified cleaning efforts, it is impossible to eliminate the presence of flotsam on local beaches as, during each high tide, new waves of flotsam from the open sea will be washed onto Singapore’s shores.

“To prevent litter from land-based sources from being washed into the ocean, most of our rivers and canals have been dammed up and there are measures such as drain slabs, litter traps, vertical gratings and float booms to trap debris and litter,” it added.

The public can play a part in keeping Singapore clean by joining existing groups in clean-up efforts or organising their own clean-ups.

Those interested in doing so are advised to be prepared with masks, gloves, hand sanitiser, tongs and rubbish bags.

Alternatively, these items can be borrowed from CleanPods. This can be done by registering a clean-up at www.publichygienecouncil.sg/beachcleanup/

Once registered, users can collect the tools from CleanPods, which can be found in beaches and parks such as Changi Beach Park, East Coast Park and Pasir Ris Park.
