Biodegradation Testing

In recent years, ubiquitous plastic products have made environmental pollution more and more serious.Europe, the United States, and China have successively introduced "plastic restriction orders" to prohibit the production and sale of certain plastic products and promote green plastic products.
CTI provides professional biodegradable testing services.Applicable products include disposable tableware, postal express packaging products, hotel supplies, resin and starch products, and plant fiber molded products.

Biodegradation Testing

◉    Service Background

At the beginning of this year, the strongest plastic limit order has been issued, which caused a heated debate. Plastic products can no longer be used "willfully". According to incomplete statistics, up to now, 24 provinces in China have successively issued implementation plans of the "plastic restriction orders". China, EU, USA and other countries have issued "plastic ban", banning the use of certain non-degradable plastic products. So in this context, the research and development of highly efficient degradable plastics has become an important topic in the field of plastics and packaging, and has become a global hot spot. CTI can provide professional biodegradability testing services according to different products and testing standards to help enterprises control the quality and safety of materials.

◉    Common Problem

Q: What’s the meaning for Biodegradability?

A: Biodegradability, also known as biolysis, refers to degradation caused by biological activity. As the material is gradually digested by microorganisms as a nutrient source, it will lead to mass loss and degradation of properties such as physical properties, etc., and eventually decompose the material into CO2, H2O, methane, mineral salts and other substances.

Q: Which are common biodegradable plastics?

A: The most common biodegradable plastic is PLA. Others such as PBS, PBAT, PBSA, PCL, PCL, Starch, PGA, PVA, PHA, etc.
