Baltic Sea Beach Clean-up: What the Priwall’s Hidden Trash Reveals

At first glance, the Baltic Sea beach at Priwall looked almost spotless. A gentle autumn breeze, dogs running along the sand, and barely any visible waste. But during our recent clean-up with Trash Hero Lübeck, we decided to look a little closer — and discovered that even “clean” beaches can hide an alarming amount of pollution beneath the surface.

A collaboration driven by shared purpose

Trash Hero Lübeck, led by the energetic and passionate Daniel, has been organizing regular clean-ups in and around Lübeck since the beginning of 2024 — already collecting over 10 tons of waste and more than 98,000 cigarette butts in just 30 clean-ups.
We joined forces for a second time this year now and the collaboration is a perfect fit: both of our teams share the same goal — keeping our environment clean and learning from what we find.

A closer look: What the sand was hiding

Besides the general collection, we focused on a specific 10 x 15 meter section of beach — an area without an active tide line, where we wanted to see what the sand was hiding from plain sight.

After just an hour of meticulous work, the results were shocking.

  • Glass: 85 fragments in green, brown, and clear. Some tiny, others dangerously sharp — clear evidence of broken bottles at this popular dog beach, posing real risk for both people and animals.

  • Plastic: 51 pieces of various types — packaging scraps, foil, capsules, hard and soft plastic fragments, many brittle and weathered. Among them were bag remnants, cable coatings, and bits of colorful microplastic.

  • Paper & textiles: 35 pieces, mostly decomposed, unrecognizable scraps — traces of packaging and paper fibers.

  • Metal: 3 bottle caps, 2 can fragments, and one corroded metal seal.

  • Rubber & other: Several small black pieces, likely from shoes or cables.

Over 170 individual items — in an area smaller than a classroom.
According to EU standards, more than 20 pieces per 100 meters already pose a risk to humans and the environment. This beach far exceeded that threshold.

What these findings tell us

Because this was not an active shoreline, we couldn’t record the data in standard clean-up apps. Instead, we spread the findings on a white tarp and analyzed them together.
That hands-on moment brought home an important realization:

Even where pollution isn’t visible, it’s still there — embedded in the sand, broken down, overlooked.

We discussed how macro-, micro-, and nanoplastics travel from rivers to the sea, and how currents and winds bring them back to our shores. Seeing the fragments up close sparked questions, conversations, and reflection — exactly what makes clean-ups so valuable beyond the act of collecting.

Community, curiosity, and collaboration

Twenty participants, three children, and two dogs joined today. Together we removed 124 kilograms of trash and 791 cigarette butts in just three hours.
But more importantly, we built awareness — and connection.

Daniel’s energy and commitment continue to inspire many around Lübeck, and we’re looking forward to deepening this collaboration. Next year, we hope to combine one of our recycling workshops with a Trash Hero Lübeck clean-up to show how waste can be transformed into new resources — turning awareness into circular action.

Looking closer pays off

This clean-up reminded us that what we don’t see can still have a huge impact.
Even beaches that seem clean often hide traces of our everyday life — glass shards, plastic bits, and fibers quietly breaking down into smaller and smaller pieces.

But when we take the time to look closer, we not only uncover hidden trash — we uncover awareness, responsibility, and community.
Every piece we pick up tells a story about how connected we are to our environment, and how much difference we can make together.

Change starts right where you are.

You don’t have to live by the sea to take action.
Join a clean-up in your area, start one with friends, or simply take a bag on your next walk.
Each small act of care helps protect the places we love — from the Baltic shorelines to your local park.

Find a clean-up near you, get involved, and keep looking closer.
