Third annual clean-up finds less pollution than in 2025, with Central Trinity Gully now free of new single use pollution.

The British Mountaineering Council (BMC) along with its key partners has completed its third annual Yr Wyddfa Big Clean Up, with volunteers and professional mountaineers removing a further 3,706 items of single-use pollution from the mountain. The surveying completed by Trash Free Trails showed that 84% of the items collected were single-use plastic, with 13.7% potentially preventable through a Deposit Return Scheme (DRS) and 39.2% qualifying for Extended Producer Responsibility (pEPR).

The 2026 clean-up found less pollution than in 2025, despite similar levels of volunteer participation. The results also mark a significant milestone for the project, with no new items of rubbish found in Central Trinity Gully following three years of targeted clean-up work. The gully is now considered free of single use pollution after 11,283 items of pollution have been removed since 2024.

Central Trinity Gully has been a particular focus of the project because its steep terrain and topography can cause pollution to accumulate, while also being an important habitat for plants and invertebrates.

Tom Carrick, BMC Access & Conservation Officer for Wales, said:

“We're concentrating particularly on this area not just because it's a bit of a topographical trap for pollution to be building up in, but because it's also a really important habitat for a huge amount of both plant and invertebrate species that call this place home.”

Across the wider clean-up, 84% of the items collected were single-use plastic. Analysis by Trash Free Trails found that 13.7% of items could potentially have been prevented through a Deposit Return Scheme (DRS), while 39.2% would qualify for Extended Producer Responsibility (EPR). Outdoor equipment and clothing accounted for 8% of the items collected.

The data gathered through the project by Trash Free Trails is contributing to a longer-term picture of pollution on Yr Wyddfa and will help inform discussions around the Deposit Return Scheme, due to be introduced in October 2027, and Extended Producer Responsibility.

The professional clean-up involved trained Mountaineering and Climbing Instructors (MCIs) accessing hard-to-reach gullies below the summit.

This year, the team introduced a highline retrieval system, enabling instructors to collect pollution simultaneously before sending bags approximately 100 metres down a 6mm power cord. The new system significantly increased efficiency, with the team collecting almost as much rubbish by lunchtime on the first day as during the whole of the professional operation in 2025.

The Big Clean Up was undertaken with careful consideration for Yr Wyddfa's sensitive habitats. The mountain is a Site of Special Scientific Interest, and volunteers worked under guidance from Plantlife to minimise disturbance.

The BMC and partners say the project's approach remains focused on education and positive engagement rather than blame, encouraging people to see litter prevention as part of enjoying and caring for the outdoors.

Dom Ferris, founder of Trash Free Trails, said:

“We're doing it because we love this place, not because we hate things.

“There are thousands of people passing us today that wouldn't have known this was going on. Some of those people will be the kind of people that are dropping single-use pollution. That's a problem because it frustrates people who work on this mountain who get upset and start to think about blaming people.

“What we have a conversation with as a group is, how do we stay positive and use any of the interactions we have with people as an opportunity to positively change behaviour. At Trash Free Trails, one of our core values is that we'll always be positive and we never use blame or shame or guilt or aggression as a tactic. Firstly, because we don't want to. Secondly, because it doesn't work.”

The BMC is encouraging people to take the same approach on their own outdoor adventures by picking up items of pollution where they can, taking their waste home and helping to protect the places they enjoy.

The BMC is grateful to Deuter, through the European Outdoor Conservation Association (EOCA), and Grangers for their support, alongside collaboration with Trash Free Trails, Plantlife Cymru & Natur am Byth, Cymdeithas Eryri (Snowdonia Society), Eryri National Park Authority and the Baron Hill Estate.

Data on single-use pollution is provided by Trash Free Trails as part of its State of Our Trails Research programme, supported by Bosch eBike Systems, Bangor University and Fusion Media.
