The general definition of recycling is "to reduce the environmental burden by recycling". It is true that you can recycle a lot of times, but it also results in a lot of energy loss and remains as garbage. On the other hand, biodegradation is "COMPOSTABLE" and does not produce waste.
It is said that it takes several hundred years (6-7 hundred years) for so-called "synthetic fibers" to decompose naturally without any action. The "biodegradable synthetic fibers" we have developed are decomposed by specific microorganisms into a small amount of water (H2O) and carbon dioxide (CO2) in a very short period of time.
Therefore, they do not decompose naturally even if they are left in the back of the closet or outdoors, and their carbon dioxide emissions are about 40% less than those of burning waste or recycling. This microbial disposal process is already widely used in organic waste disposal as "COMPOSTABLE".
