Biodegradable plastics were first introduced in the late 1980s, and confusion and skepticism have persisted since then about the claims and product performance.

Although such materials are touted as environmentally friendly, some biodegradable plastic products were not biodegradable at first as expected. However, the companies that produce these materials have claimed that they are biodegradable, even though there is no scientifically based test method and standard.

However, today the situation has changed. After 2002, it has been scientifically proven that a material will biodegrade and leave no synthetic residues, and new test methods and certification programs have been developed.

The first published biodegradable material standards were the following standards developed by the American Society for Testing and Materials (ASTM):

• ASTM D6400-19 Standard specification for labeling plastics designed to be composted aerobically in municipal or industrial facilities
• ASTM D6868-21 Standard specification for the labeling of finished products containing plastics and polymers as coatings or additives with paper and other substrates designed to be composted aerobically in municipal or industrial facilities

The ASTM D6400-19 standard covers plastics and products made from plastics designed for composting in municipal and industrial aerobic composting facilities. The specifications contained in this standard are those required to determine whether plastics and products made from plastics will compost satisfactorily, including biodegradation at a rate comparable to known compostable materials.

ASTM D6868-21 describes requirements for labeling materials and products, including packaging, where a biodegradable plastic film or coating is added to compostable substrates and the entire product is designed to be composted. Essentially, this standard requires the product to compost satisfactorily: proper decomposition during composting, adequate natural biodegradation, and no adverse effects on the composts' ability to support plant growth.

Today we have come to the point where biodegradable materials have the functionality of existing products, but will biodegrade completely and safely without leaving any residue when composted in a large facility.

Our organization always follows domestic and foreign standards, applicable legal regulations and generally accepted practices in certification and labeling studies, and also has a trained and experienced staff and advanced technological facilities. In this context, requesting businesses,It also provides compost certification and C-Label (Compost Labeling) compost labeling services.
