生物降解顆粒：“全生（shēng）物降解塑料”與“可降解塑料（liào）”的區別

　“全（quán）生物降解塑料”與“可降解塑料”的區別

The difference between "fully biodegradable plastics" and "degradable plastics"

　　近年來，環境保護已成為全球關注的主題，我國也出台了一係列諸如“限（xiàn）塑令”的政策，既有政策扶持又有技術發展，降解塑料製品在當今社會被大（dà）量使用。降解塑料被分為“可降解”和（hé）“全降解”兩類。下麵我（wǒ）們將區分“可降解”和“全降（jiàng）解”塑料。

In recent years, environmental protection has become a global concern, and China has also introduced a series of policies such as "plastic restriction orders", which provide both policy support and technological development. Degradable plastic products are widely used in today's society. Degradable plastics are divided into two categories: "degradable" and "fully degradable". Below, we will distinguish between "degradable" and "fully degradable" plastics.

　　什麽是“可降（jiàng）解”塑料：

What is "biodegradable" plastic:

　　“可（kě）降解”塑料是在聚（jù）乙烯（xī）中加入一定量的生物材（cái）料（如玉米（mǐ）澱粉、甘油及其他生產助（zhù）劑），使得塑料袋穩定性下降，較容易（yì）在自（zì）然環（huán）境（jìng）或（huò）符合一定的條件下的環境中碎化。

"Degradable" plastic refers to the addition of a certain amount of biomaterials (such as corn starch, glycerol, and other production additives) to polyethylene, which reduces the stability of plastic bags and makes them easier to break in natural environments or environments that meet certain conditions.

　　什麽是“全生物降解”塑料：

What is "fully biodegradable" plastic:

　　在自然條件下，受溫度、水、光和（hé）氧氣等因素的影響，不同於生物破壞性塑料，全（quán）生物降解塑料不含生（shēng）物無法降解的成分，因此可以被（bèi）微生（shēng）物（wù）完全分解而沒有（yǒu）殘留，這就就是全生物降解（jiě）塑料。

Under natural conditions, influenced by factors such as temperature, water, light, and oxygen, unlike biodegradable plastics, fully biodegradable plastics do not contain components that cannot be biodegraded. Therefore, they can be completely decomposed by microorganisms without residue, which is called fully biodegradable plastics.

　　“全（quán）生物降解（jiě）塑料”與“可降解塑（sù）料”兩者有什麽區別（bié）：

What is the difference between "fully biodegradable plastics" and "biodegradable plastics"

　　可降解塑料裏（lǐ）麵添加了一定量的可降（jiàng）解的生物材料，但是裏麵原有（yǒu）的不可降解塑料（liào）成分依然不可降解，產生的微塑料顆粒對日後環境，尤其是水體和土質影響是非可視化的，且影響深遠。而全生（shēng）物降解塑料在自然界，如（rú）土壤、沙土等條件下，或特定條件如堆（duī）肥條件下或厭氧消化條件下或水性培養（yǎng）液中，由自然界存在的微生物如細菌、黴菌和海藻等作用引起降解，並終完全（quán）降解變（biàn）成二氧化（huà）碳、水及其所含（hán）元素的礦化無機鹽以（yǐ）及新的生物質的塑（sù）料，不汙染空氣和土壤。

A certain amount of biodegradable biomaterials are added to degradable plastics, but the original non degradable plastic components inside are still non degradable. The resulting microplastic particles have a non visual and far-reaching impact on the future environment, especially on water and soil quality. And fully biodegradable plastics are degraded in nature, such as soil, sandy soil, or under specific conditions such as composting, anaerobic digestion, or water-based culture media, by the action of microorganisms such as bacteria, fungi, and seaweed that exist in nature, and ultimately completely degrade into carbon dioxide, water, and the mineralized inorganic salts of the elements it contains, as well as new biomass plastics, without polluting the air and soil.

　　所以“全生物降解塑料”才是真正的環保塑料！

So "fully biodegradable plastics" are truly environmentally friendly plastics!
