Biodegradable in Marine Environment

Incredible amounts of waste, most of it plastic, enter the sea every year. The main sources of entry are, for example, abrasion from car tires, fiber loss during washing, or simply littering (especially in countries without functioning waste management). However, ghost nets also pose a problem. Due to this continuous input, a progressive accumulation of persistent plastic in the sea takes place. It is a fact that a subsequent cleaning of the oceans from plastic waste is almost impossible, also because plastic decomposes over time through mechanical stress and weathering into smaller and smaller pieces (microplastics).

Fortunately, there are now many materials, including certain bioplastics, that have been shown to be decomposed by microorganisms in the sea. Using as many of these biodegradable materials as possible, for example in fishing gear, can help prevent lost nets from remaining in the sea indefinitely.

The use of materials that degrade in the sea thus represents an important aspect of combating the littering of the oceans that is progressing worldwide.

Trust is good - DIN-Geprüft/DINplus is better!

Together with experts from research, testing and industry, a certification committee developed a certification scheme for testing and evaluating marine biodegradable products.

We test and certify according to ISO 22403, the first international standard for the assessment of intrinsic biodegradability of materials in marine environments. In addition to biodegradability, the certification scheme "Biodegradable in Marine Environments" also defines criteria for marine toxicity and disintegration. The content of heavy metals and other substances of concern are also taken into account.

With DIN certification, manufacturers document that their products meet all the requirements specified in the standard and that their products have been voluntarily tested and certified by neutral, independent and competent bodies.

Testing according international standards

The international Standard ISO 22403 is the basis of our certification scheme "Biodegradable in the Marine Environment". The following audit evidence is required:

  • Chemical characterization (including heavy metal content).
  • Test for intrinsic biodegradability in the marine environment
  • Disintegration rate in the marine environment
  • Marine ecotoxicity
  • Infrared transmission spectrum

For DINplus additionally:

  • Disintegration in a real marine environment

The tests are carried out in a testing laboratory recognized by DIN CERTCO. First, we evaluate the material composition and determine the test scheme. If your product meets the above requirements, you will receive the corresponding certificate and may use the mark "DIN Geprüft - Biodegradable in the Marine Environment" and/or "DINplus- Biodegradable in the Marine Environment" for your product.

The certification is valid for five years, certificates for materials, semi-finished products and additives are valid for six years. To ensure that all certified products are compliant at all times, we regularly monitor the certified products.

FAQ

How can I get my product certified?

Simply fill out the application form for certification to start the certification process. For the technical evaluation, we need the information of all ingredients as well as the safety data sheets. Of course, this information will be treated confidentially.

Feel free to contact us if you have any questions in advance or would like a non-binding offer. We will be happy to support you.

What does certification cost?

According to the fee schedule, the fees for a "simple" certification for all materials, semi-finished products, additives and products are identical for all applicants. Testing costs can be included once the test scheme is defined. Please contact us. We will be pleased to submit you an individual offer, also for both marks.

How long does the certification process take?

This depends entirely on the scope of testing required, which is determined after receipt of the application on the basis of the formulation and ingredients. Testing for biodegradability can take up to 2 years.

What factors influence the biodegradability of a product?

The biodegradability of a material is a system property that is essentially the result of three conditions:

a) The potential biodegradability of the material.

b) The available surface area and shape of the product

c) The environmental conditions at the site of the product

Why can't packaging be certified?

Certain products, such as packaging, are not intended to be used or remain in the marine environment. By collecting and recovering the materials (recycling, composting), the material cycle is closed and added value is created. We also offer certifications for this, e.g. recyclability , recyclates or industrial compostability . Feel free to contact us!
