濟(jì)南塑料袋;多久才會(huì)無蹤跡？

　　塑料袋降解后的產(chǎn)物主要取決于其材質(zhì)和降解方式。以下是幾種常見的降解塑料袋及其降解后的產(chǎn)物：

　　The products of plastic bag degradation mainly depend on its material and degradation method. The following are several common degradable plastic bags and their products after degradation:

　　物理降解 ：

　　Physical degradation:

　　市場(chǎng)上常見的降解塑料袋通常在原料中添加了淀粉，在填埋后，由于淀粉的發(fā)酵和細(xì)菌的分解，塑料袋會(huì)分解成細(xì)小甚肉眼看不見的碎片。

　　The commonly used biodegradable plastic bags in the market usually add starch to the raw materials. After landfilling, due to the fermentation of starch and the decomposition of bacteria, the plastic bags will decompose into small or even invisible fragments.

　　化學(xué)降解 ：

　　Chemical degradation:

　　可降解塑料在制造過程中加入了添加劑，如淀粉、變性淀粉、纖維素、光敏劑、生物降解劑等，使其在自然環(huán)境中更容易降解。

　　Degradable plastics are manufactured with additives such as starch, modified starch, cellulose, photosensitizers, biodegradable agents, etc., making them easier to degrade in the natural environment.

　　降解后的產(chǎn)物可能包括二氧化碳、水、無機(jī)鹽等，但通常這些塑料在自然環(huán)境中的降解效果并不明顯。

　　The products of degradation may include carbon dioxide, water, inorganic salts, etc., but usually the degradation effect of these plastics in the natural environment is not significant.

　　生物降解 ：

　　biodegradation:

　　完全可生物降解塑料袋的原料來自玉米、木薯、淀粉等，在自然環(huán)境中可以被微生物完全降解，終分解成上述的產(chǎn)物。

　　The raw materials for fully biodegradable plastic bags come from corn, cassava, starch, etc., which can be completely degraded by microorganisms in the natural environment and ultimately decomposed into the above-mentioned products.

　　快速降解技術(shù) ：

　　Rapid degradation technology:

　　采用快速降解技術(shù)，使用易降解的高聚碳?xì)浠衔锖陀袡C(jī)物制造塑料，以減少對(duì)環(huán)境的影響。

　　Adopting rapid degradation technology, using easily degradable high hydrocarbons and organic compounds to manufacture plastics, in order to reduce the impact on the environment.

　　全降解塑料袋 ：

　　Fully biodegradable plastic bags:

　　由PBT（聚對(duì)苯二甲酸丁二醇酯）、PLA（聚乳酸）和玉米淀粉合成的改性原料制成的袋子，在土壤中大約3個(gè)月可以完全降解。

　　A bag made from modified materials synthesized from PBT (polybutylene terephthalate), PLA (polylactic acid), and corn starch can be completely degraded in soil for about 3 months.

　　需要注意的是，盡管這些塑料袋在特定條件下可以降解，但它們通常需要特定的工業(yè)堆肥條件才能完全降解，而在自然環(huán)境中，這些塑料可能不會(huì)完全降解，其降解產(chǎn)物仍可能對(duì)土壤和水源造成影響。因此，減少使用一次性塑料袋和推廣可降解塑料袋仍然非常重要

　　It should be noted that although these plastic bags can degrade under specific conditions, they typically require specific industrial composting conditions to fully degrade, and in the natural environment, these plastics may not fully degrade, and their degradation products may still have an impact on soil and water sources. Therefore, reducing the use of disposable plastic bags and promoting biodegradable plastic bags remain very important
