Darum geht’s beim “Keimling”: 

In an ever-growing market of products labeled as “sustainable”, certificates provide security for consumers. The so-called Keimling is one of these certificates that have been introduced throughout Europe so that people like you can be sure that they are holding a truly sustainable product in their hands. The basis for the “Keimling” certificate is DIN EN 13432.

EN 13432: The Keimling at a glance

Core statement of the Keimling

Products with this label are at least 90 percent biodegraded in industrial composting plants within 6 months or 90 percent composted within 3 months. This includes not only the plastic used, but all components of the product. Here we explain the terms “biodegradable” and “compostable” in more detail: “Biodegradable, compostable, biobased, recyclable – meaning and difference”.

EN 13432 in detail - this is what lies behind the Keimling

The Keimling is a trademark that can be awarded to plastics to demonstrate their compostability and biodegradability.

For consumers, the Keimling indicates that the appropriately labeled product will completely decompose in a composting plant within a few weeks.

The Keimling not only indicates that the plastic itself is biodegradable and compostable. The certificate also establishes the corresponding degradability for the components associated with the product, such as labels, inks, adhesives and the like.

The label was created by the European Bioplastics Association.

This association is an association of dealers who sell plastics labeled as compostable and biodegradable. As an association, the traders voluntarily undertake to have their plastics certified with the Keimling in accordance with DIN EN 13432.

The Keimling is used in many countries throughout Europe. You can find the seal, for example, on products in:

What does compostability mean?

Compostability in the sense of the certificate means: In an industrial composting plant with a temperature of about 60 degrees Celsius, the majority of the appropriately labeled product is decomposed to water, carbon dioxide and minerals within 12 weeks. Composting is considered successful when, after screening through a sieve with a 2-millimeter opening, only a maximum of 10 percent of the mass originally put in remains.

Composting is considered the most sustainable way to dispose of waste because it significantly reduces the amount of organic waste. In turn, the resulting compost can be used for raised beds, ornamental plants or horticulture. Why composting is such a great opportunity for environmental protection is also explained in this video:

The requirements behind the "Keimling" certificate

Certification with the Keimling is based on standards that have been harmonized at EU level. This means that the different standards of various member states have been harmonized in their requirements, so that the Keimling can serve as an EU-wide certificate. The corresponding relevant standards are:

For certification, the plastic is first chemically tested:

It is then determined whether the material is biologically degraded to carbon dioxide (CO2), among other things, in an aqueous medium, i.e. under the influence of oxygen. This test is considered to be met if at least 90 percent of the organic material has been converted to CO2 within six months.

In addition, it is tested whether the material is disintegrated into compost. For this purpose, a maximum of 10 percent of the original mass may remain after three months of composting, after screening through a 2-millimeter sieve.

In addition, the material is tested for interactions and toxicity. This means the material must not have a negative effect on the composting process itself. Nor should the material release toxins into its environment that could negatively affect plant growth.

For a product to receive the Keimling, it must successfully pass all tests. The tests are based on the scientific definitions for

This is what distinguishes the Keimling from OK compost INDUSTRIAL and OK compost HOME

The two OK compost certificates differ mainly in their statement about the compostability of a product.

Products with the OK compost INDUSTRIAL certificate

The OK compost HOME certificate, on the other hand, is not based solely on a standard. Rather, the seal lists all the technical requirements necessary for certification of the product. Products with this seal are generally compostable even at low temperatures, i.e. even on home garden compost.

In Germany, DIN CERTCO also awards the certificate called “DIN-tested garden compostable” for products that can be composted at home.

Products certified with the Keimling at BIOvative

One example of a product that has been certified with the Keimling is our compostable organic bags. The bags are fully compostable and biodegradable. They are also made from renewable, European raw materials – production takes place locally in Germany. All our products proudly carry the Keimling certificate and have also been awarded the OK compost INDUSTRIAL, OK compost HOME and DINplus certificates. What this means for you: With our organic bags, you can easily contribute your share to a more sustainable future.
