Plastic At Sea :
two labels to preserve
marine ecosystems

The “Non-Toxic” and “Biodegradable and Non-Toxic” labels, developed by Plastic At Sea, are essential to promote plastic sustainability and reduce marine pollution.

to Plastic At Sea

Plastic At Sea, founded in August 2018 by Dr. Anne-Leila Meistertzheim, is a company based in Banyuls-sur-Mer in the Pyrénées-Orientales. We help businesses assess the ecological impact of their plastic products and adopt environmentally friendly alternatives in a circular economy approach.

Our expertise in biodegradability and toxicity of marine plastics enables us to provide innovative and effective solutions to preserve marine ecosystems. Plastic At Sea is supported by the Banyuls Oceanological Observatory, the town of Banyuls-sur-mer, the Occitanie Region and BPI.

Why fight
against plastic pollution?

Plastic pollution is a major societal issue, threatening marine biodiversity and ecosystem health. With annual plastic production continually rising, plastic waste, visible or in the form of microplastics, accumulates in the oceans, impacting the food chain and human health. In response to this crisis, promoting sustainable solutions is crucial.

The “Non-Toxic” and “Biodegradable and Non-Toxic” labels in marine environments play a crucial role in guiding consumers and businesses towards more responsible practices, helping to protect our environment and our health.

Our labels


The “Non-Toxic” and “Biodegradable and Non-Toxic” labels, developed by Plastic At Sea, are essential to promote plastic sustainability and reduce marine pollution. These labels certify that a plastic product is environmentally friendly, biodegradable, and non-toxic, based on rigorous testing currently undergoing standardization. They serve as evidence of commitment to responsible practices.

Who are they for?

These labels are aimed at polymer manufacturers and processors, and apply to products containing polymers (including inks and adhesives) or plastic components, who wish to adopt environmentally friendly practices.
They also target consumers, offering them a way to recognize and support businesses committed to protecting the marine environment.

& transparency

Evaluation grid for obtaining labels

To obtain our labels, materials must meet several rigorous criteria :

1. Achieve a minimum percentage of biodegradation after 4 months or 90% after 24 months, compared to cellulose.
2. Not induce toxic effects after micronization and 2 months of leaching.
3. Maintain levels of HSP70, stress indicators, similar to those exposed to cellulose after 100 days.
4. Present glycogen quantities equivalent to those observed in organisms exposed to cellulose after 100 days.
5. Ensure shellfish growth not lower than organisms exposed to cellulose after 100 days.

For the Non-Toxic label, only criteria 2 to 5 must be respected.

Application terms

Certification by Plastic At Sea allows the display of the “Non-Toxic” or “Biodegradable and Non-Toxic” labels, accompanied by its logo, on compliant products. This designation ensures that products have been rigorously tested and meet defined environmental requirements.

of adopting the Label

By opting for labeled products, businesses meet consumers’ growing expectations regarding sustainability and strengthen their position in the market as responsible actors committed to environmental preservation.


CEE Schisler Packaging Solutions

Our Earth Cup® in cardboard without plastic film was already recyclable and compostable at home. To limit any risk of persistence in the environment, we decided to subject it to the biodegradability and non-toxicity at sea analyses developed by Plastic at Sea: the monomaterial of our cup behaves like pure cellulose. The absence of long-term impact on marine ecosystems has been validated!
