EPI supports the development of international standards relating to the establishment of practical and measurable specifications and methods for the testing of degradable and biodegradable products.

Degradation and biodegradation requirements of plastics vary considerably with intended use including disposal compartments and EPI is working with ASTM and European standards to evaluate oxo-biodegradable claims in various environments such as landfill, soil, litter, commercial and home composting.

Unfortunately, at the present time, there are no standards available for the performance of degradable and biodegradable plastics in other disposal environment other than composting. Commonly quoted standards for compostable plastics are ASTM D and EN and are related to the performance of plastics in a commercially managed compost environment and are not biodegradation standards.

Both standards were developed for hydro-biodegradable polymers eg. This does not mean that they will not biodegrade; they just convert the carbon to carbon dioxide in a slightly longer time frame. Many naturally occurring materials, all biodegradable, do not convert in the time frames established by ASTM D and EN , which are explained in the Position Statement. ISO is an international standard that specifies the need for proof of performance in labeling and packaging of products claiming to provide an environmental benefit.

EPI follows this standard and requires its licensees to do so as well. Founding member of OBPF. All rights reserved.

Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More D This enables a laboratory assessment of its disposal performance in, soil, compost, landfill, and water and for use in agricultural products such as mulch film without detriment to that particular environment. However, exposure of a similar material of known outdoor performance, a control, at the same time as the test specimens allows comparison of the durability relative to that of the control under the test conditions. Disposal environments range from exposure in soil, landfill, and compost in which thermal oxidation may occur and land cover and agricultural use in which photooxidation may also occur. The conditions should include a range of humidity or water concentrations based on the application and disposal environment in mind.

Print Email. Please help to explain the difference between biodegradable vs. I have read through several definitions but am still not quite clear on it. Both seem to end up with CO2, H2O and biomass, while biodegradable will be degraded by microorganisms. But some compostable material might be involved with microorganisms as well. Is this right? The definition I was given is that biodegradable usually means that a commercial facility can cause the product in question to breakdown into usable materials.
