Biodegradability and Compostability

Do you need to know if your product is biodegradable in a particular environment? Is your product biodegradable under aerobic and anaerobic conditions? Does your product meet compostability regulation requirements? Do you need to certify your compostable product at industrial and/or home level?

At AIMPLAS, we carry out all the studies required by companies to demonstrate and certify that their product is compostable.

We also carry out laboratory studies, offer advice during the product development process and provide support during the certification process.

Studies in accordance with standards

We are able to carry out compostability studies in accordance with the following standards:

  • EN 13432. Packaging. Requirements for packaging recoverable through composting and biodegradation. Test scheme and evaluation criteria for the final acceptance of packaging.
  • EN 14995. Plastics. Evaluation of compostability. Test scheme and specifications.
  • ISO 17088. Plastics. Organic recycling. Specifications for compostable plastics.
  • ASTM D 6400. Standard specification for labelling of plastics designed to be aerobically composted in municipal or industrial facilities.

Laboratory testing

Chemical characterization and identification of samples

Control of components known or expected to be harmful to the environment and to exceed standard specifications during the biological treatment process. It is necessary to determine the content of heavy metals and fluorine, and to identify the sample and any volatile solids.

Aerobic biodegradation

Degradation of an organic compound into carbon dioxide, water, mineral salts and new biomass by the action of microorganisms in the presence of oxygen. In order to determine if a product is biodegradable, it is first necessary to define the environment of this biodegradation.

  • Controlled composting in accordance with standard ISO 14855.
  • Soil medium in accordance with standard ISO 17556.
  • Aqueous medium in accordance with ISO 14852.

Anaerobic biodegradation

Degradation of organic matter through the combined action of different microorganisms in the absence of oxygen.

The products generated include new biomass and biogas (a mixture of methane, carbon dioxide and traces of sulphuric acid), which has high potential for producing electricity and heat. The standard used is ISO 15985..

Grado de desintegración

Disintegration

Physical process involving the fragmentation of plastic material in the final compost. The degree of disintegration can be determined at pilot and laboratory scale.

  • Disintegration in a pilot-scale test ISO 16929
  • Disintegration in a laboratory-scale test ISO 20200

Ecotoxicity

The physico-chemical properties of the final compost (compost quality) are analysed and the ecotoxicological effects on higher plants are determined in accordance with standard OECD 208 and Annex E of standard EN 13432.

Accreditations and recognition

AIMPLAS laboratories are accredited in accordance with international quality standard UNE-EN ISO/IEC 17025 and also by ENAC to carry out biodegradation studies in compost and soil, and disintegration studies at laboratory scale.

We are also recognized by the certifying body TÜV Austria to carry out the complete compostability test scheme to enable companies to obtain the ecolabels OK Compost INDUSTRIAL, OK Compost HOME and the Seedling logo, as well as OK Biodegradable SOIL.
