Plastic items make up majority of litter in Scotland’s rivers and waterways

The first national volunteer survey of litter found by Scottish rivers and waterways has revealed that plastic bottles were the most littered item, followed by plastic pieces, plastic snack packets, drinks cans and polystyrene pieces.

With 80% of marine litter coming from land, our Upstream Battle® campaign focuses on raising awareness, gathering evidence and inspiring action to change littering behaviour to prevent marine litter at source along rivers in Scotland.

The recently published Upstream Battle® Citizen Science Report – a snapshot of data gathered by volunteers across a three-month period between December 2023 and February 2024 – consists of 185 surveys conducted along 26 rivers and waterways in 20 local authority areas across Scotland. It forms part of the national rollout of the campaign, aimed at understanding and addressing marine litter across the country.

In total 20,383 items were counted during the survey period, with the majority of litter found to be items which would be addressed under a Deposit Return Scheme (DRS) or effective Extended Producer Responsibility (EPR) regulations.

The rest of the top 10 items littered include cigarettes, glass fragments, dog poo, plastic bottle caps and plastic bags.
