The betrayal of the mixed prince?

The plastic Industry Technology Development Center (abbreviation: plastic Center) has the only biodegradation laboratory in China that has obtained the three-party certification of BpI in the United States, compostable spoonsDincertco in Germany, and the Environmental protection Agency. In recent years, major domestic and foreign brands have proposed to replace existing plastics with biodegradable plastics. Many suppliers have sent their own raw materials for verification. Huang Yuping, a specialist in the analysis business group of the Analytical Technology Department, said that the plastic center has completed the expansion of the laboratory this year. Currently, about a dozen sets of samples can be inspected, but customers still need to wait in line. After August next year, because the amount of inspection is very large.

Most of the plastic restriction policies proposed by countries around the world allow the use of alternative materials, but they need to pass a complete and rigorous "compostable plastic" (compostable) certification. "Compostable plastic needs to go through the two levels of biodegradable and compostable experiments to get it. Certification." He said, the composition of plastic is multi-molecule polymer, not a single material. Therefore, there are also photodegradable plastics, disintegrable plastics, and oxidative technology biodegradable plastics on the market. "However, these are not Biodegradation is not compostable plastic."

"These three plastics are just traditional plastics plus other materials. They will decompose naturally, but they will not decompose and cannot be composted. The plastic fragments left after the crushing have the same physical properties as the undecomposed plastic, which is easy for users to understand." Decomposition "helps long-term waste and causes environmental pollution.?” Huang Yuping said, just as traditional plastics can be added with some other substances, biodegradable plastics may also have different additives. "Therefore, biodegradable plastics do not necessarily mean that they can be composted. It has to go through testing conditions such as decomposition rate, disintegration degree, plant cytotoxicity, heavy metals, etc., before it can be called compostable plastic."

The "Biodegradable Laboratory" of the plastics Center is the first and only laboratory institution in Taiwan that is certified by Dincertco in Germany, BpI in the United States, and TAF in China. "The laboratory is responsible for performing experiments, issuing reports, and issuing certifications. It is still certified by Dincertco, BpI and other certification units. Therefore, before conducting the test, the manufacturer needs to confirm the required test content with the certification unit."
