Biodegradable, Not Just Biobased

“Biodegradability is an end-of-life option for single-use consumer plastics that harness microbes present in the disposal environment to completely utilize the carbon substrate safely and efficaciously, and remove it from the environment. Biodegradability claims must be supported by verifiable scientific data from independent, third-party testing laboratories using established international (ISO) or national (ASTM, EN) standard test methods and specifications.”*

Not all biobased plastics are biodegradable. The majority of bioplastics and biodegradable plastics are biobased but have limited or no biodegradability. Mirel bioplastic resins are the only non-starch bioplastics certified by Vinçotte for biodegradability in soil, home compost, industrial compost, and natural water environments. Mirel bioplastic resins may help to reduce waste sent to landfills and may increase composting at home or at industrial composting facilities.

The rate and extent of Mirel’s biodegradability will depend on the size and shape of the articles made from it. Mirel is not designed to effectively degrade in landfills. Industrial composting facilities may not be available in your geographic area.
