The biodegradability More of PHAsPolyhydroxyalkanoates (PHA) or the polyhydroxy fatty acids, are a family of biodegradable polyesters. As in many mammals, including humans, that hold … More has been studied for decades. But what does it mean “biodegradableBiodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. More”? We might imagine a plastic bag slowly disappearing in the ocean, but it is not the whole story. Let’s get more proper picture about the biodegradability More.
The principle of biodegradationBiodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. More is based on the activity of living organisms in the degradation process. The microorganisms are the actors of biodegradability More in the most cases. Here we focus on the biodegradability More of polymers.
If something is biodegradableBiodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. More, it does not mean it can be littered into the environment without regrets. No waste should get into free ecosystems.
The word “biodegradableBiodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. More” should never stand alone. It is meaningless, if not specified WHERE the material is biodegradableBiodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. More.
