Vegeplast 1

VEGEMAT®, the 100 % biodegradable
and compostable material.

 

Most VEGEMAT® formulations are biodegradable by composting that complies with the EN 13432 standard attested by a certified laboratory.
All VEGEMAT® formulations are biodegradable in a few days or a few months depending on the applications.

VEGEMAT® biodegradation

The “bio” prefix is sometimes improperly used as a sales argument to highlight the eco-friendly character of a specific material.

This term should, however, be reserved for degradation processes that imply living organisms through the intervention of different enzymes that stimulate degradation.
It is this point that is emphasized in the various definitions proposed by research institutions.

 

Degradation process:

Nevertheless, although these definitions justify and restrict the use of the term “biodegradation” to certain degradation conditions, they do not always make it possible to reach the conclusion of compatibility between a biodegradable material and the storage in a natural ecosystem such as compost or an aqueous environment for example.

According to some definitions, a material may be subject to biodegradation and, as such, be considered as biodegradable, without having totally disappeared from the environment. It can, therefore, linger in this same environment in the form of fragments that are more or less substantial, without ever disappearing or it may disappear over a period of time that is far too long.

The term “biodegradable” plastic does not really make sense unless it is clearly related to a period of biodegradation time for a given storage environment (compost, ground, sea, etc.).

 

VEGEMAT® composting

The purpose of eliminating biodegradable plastics by composting is to mix end-of-life materials with different organic waste at the beginning or at the end of the composting process.
The material must undergo biodegradation in this type of environment without any toxicity occurring and without any reduction in the quality of the compost. This last point is extremely important because the interest of such a process is to eliminate troublesome waste through a natural process and obtain high-quality compost that may be used as an organic improver for a variety of crops.
If the compost obtained is toxic for the plants or of poor quality, then its market value is nil and, in turn, it becomes unusable waste and leads to problems identical to those related to the storage of non-biodegradable synthetic polymers.

 

VEGEMAT® is a biodegradable plastic complying with the
EN 13432 standard.

This standard is applied for clearly characterizing the biodegradability of plastic packaging through composting.
It stipulates the performances that plastic packaging must reach to be eliminated through industrial composting
without the quality of the end-compost being modified.

It is applicable to shaped material and is divided into three main steps:

 

Step 1 »

  • Assessing the inherent degradation of the material.
    The material, in the form of powder or fine granules is placed in a mature compost. The quantity of carbon, mineralized as CO2 by the compost micro-organisms, contained in the material is assessed. To be validated, the material must be mineralized at 90% in less than 6 months.

Step 2 »

  • Estimating the fragmentation of the packaging in its form of use.
    The end-product is placed with the waste at the beginning of the composting phase, then after 12 weeks of composting, material fragments are collected. For this test to be valid, the total mass of fragments greater than 2 mm must not exceed 10% of the original packaging mass.

Step 3 »

  • Checking the quality of the compost that was used to eliminate biodegradable plastic waste.
    A germination test is carried out to compare the organic improver qualities of the compost in relation to the control compost.
