The Compostable degradable plastic certification system May 17,2021.


Compostable degradable plastic is a kind of biodegradable material, which refers to a type of material that can be completely converted into carbon dioxide, water and minerals after a certain time span under aerobic composting conditions.

    Biodegradable materials have become one of the effective ways to solve the environmental pollution problem of plastic waste because they can be degraded relatively quickly in the natural environment, which has aroused people's high attention, and countries around the world are racing to develop biodegradable materials.

Biodegradable materials have become one of the effective ways to solve the environmental pollution of plastic waste because they can be degraded relatively quickly in the natural environment, which has aroused people's attention, and countries around the world are racing to develop biodegradable materials. Compostable degradable plastic is a kind of biodegradable material, which refers to a type of material that can be completely converted into carbon dioxide, water and minerals after a certain time span under aerobic composting conditions.

The following are the evaluation standards and certifications of compostable and degradable plastics in major countries for your reference!


European Union

The compostable and degradable plastic standard implemented by the European Union is the standard En 13432 "Requirements for the final evaluation of the packaging materials recovered by composting and biodegradation" established by the European Standards Committee. It is one of the important components of the European Directive 94/62/EC. One. En 13432 puts forward requirements and limits on compostable materials from four aspects:

    A. Chemical substance restriction: stipulate the minimum content of organic substances, heavy metals and fluorine in compostable materials;

    B Biodegradability: For controllable composting materials, more than 90% must be finally converted into carbon dioxide, water and minerals within 6 months under aerobic composting conditions;

    C. Disintegration performance: stipulate the maximum thickness that the controllable compost material can be used. The controllable compost degradation material under this thickness must disintegrate more than 90% of the debris that can pass through the 22mm screen within 12 weeks of aerobic composting conditions;

    D Eco-toxicological performance: after specially selected plants are introduced into compost decomposable materials of compostable degradable materials, the original survival rate and biological characteristics of more than 90% can be achieved;

United States

    The United States is engaged in biodegradable material standards, promotion and technology development work is the Biodegradable Products Institute (abbreviated as BPI). The standard for compostable and degradable plastics currently implemented in the United States is ASTM D6400 "Specifications for Composting Plastics."

    A. Biodegradability: For a single polymer, it is stipulated that more than 60% of the controllable compost material must be finally converted into carbon dioxide, water and minerals within a maximum of 12 months under aerobic composting conditions. For blends, it is stipulated that more than 90% of the controllable composting materials must be finally converted into carbon dioxide, water and minerals within a maximum of 12 months under aerobic composting conditions;

    B. Disintegration performance: For the maximum thickness of the controllable compost material that can be used, the remaining controllable compost degradation material must be disintegrated into more than 90% of the fragments that can pass through the 22mm screen within 12 weeks under aerobic composting conditions;

    C. Eco-toxicological performance: After the selected plants are introduced into the compost decomposing materials of the controllable compost degradation material, the original survival rate and biological characteristics of more than 90% can be achieved.

Australia

    The corresponding standard established by the Australian Standards Committee to regulate the controllable compost degradation materials entering the Australian market is AS 4736 "Biodegradable Plastics-Biodegradable Plastics Suitable for Composting or Other Biological Treatment Methods"

This standard is based on the European standard En 13432, and in addition to the eco-toxicological performance requirements, an earthworm eco-toxicological test has been added.

The specific requirements are;

    A. Chemical substance restriction: stipulate the minimum content of organic substances, heavy metals and fluorine in controllable composting materials;

    B Biodegradability: It is stipulated that more than 90% of controllable composting materials must be finally converted into carbon dioxide, water and minerals within the longest month under aerobic composting conditions;

    C. Disintegration performance: It is stipulated that the controllable composting degradation material must be disintegrated into more than 90% of the fragments that can pass through the 22mm screen within 12 weeks under aerobic composting conditions;

    D. Eco-toxicological performance: After introducing the compost decomposition material of the controllable compost degradation material, the selected plants can achieve more than 90% of the original survival rate and biological characteristics, and at the same time, it must meet the requirements of the earthworm in the introduction of the compost decomposition material of the controllable compost degradation material. After reaching more than 90% of the original survival rate and biological characteristics.

Japan

    Japan's biodegradable plastic certification is called "GreenPla Certification", which was initiated by the Japan Biodegradable Plastics Association (BPS).

    From June 2000, BPS began to implement biodegradable plastic product certification standards, namely "GreenPla" logo certification, the certification standards are OECD 301C, and JIS K 6950, JIS K 6951, and JIS K 6953.

    Japan’s current standard for degradable plastics with controlled composting is JIS K 6950 formulated by BPS.

    A. Chemical substance restriction: stipulate the minimum content of organic substances and heavy metals in controllable composting materials;

    B. Biodegradability: It is stipulated that more than 60% of controllable composting materials must be finally converted into carbon dioxide, water and minerals under aerobic composting conditions, and the specific time span is not clearly specified;

    C. Disintegration performance: stipulate the maximum thickness of the controllable compost material that can be used. The controllable compost degradation material under this thickness must disintegrate into more than 90% of the fragments that can pass through the 22mm screen within 12 weeks under aerobic composting conditions;

    D. Eco-toxicological properties: Selected plants can achieve more than 90% of the original survival rate and biological characteristics after introducing the compost decomposition material of the controllable compost degradation material, or the earthworm can reach 90% after the introduction of the compost decomposition material of the controllable compost degradation material. % Of the original survival rate and biological characteristics.

China

    In 2006, my country promulgated the "Degradable Plastics Definition, Classification, Marking, and Degradability Requirements" standard. As a category of degradable plastics, controllable composting materials are clearly defined in the standard, and their biodegradability and collapse The solution performance is stipulated, and the specific stipulations are

    A. Biodegradability: It is stipulated that the controllable composting materials must be converted into carbon dioxide, water and minerals at a maximum of 60 months under aerobic composting conditions;

    B. Disintegration performance: stipulate the maximum thickness that the controllable compost material can be used. The controllable compost degradation material under this thickness must disintegrate into more than 90% of the fragments that can pass through the 22mm screen within 12 weeks under aerobic composting conditions;

    At present, the relevant test standards that my country has announced are as follows:

GB18006.1-1999 "General Technical Requirements for Disposable Degradable Tableware",

GB/T18006.2-1999 "Test Method for Degradability of Disposable Degradable Tableware",
