可生物降解塑料与普通塑料有何不同

Biodegradable plastics break down into water, carbon dioxide, and organic matter under specific conditions.
They’re made from plant starches, cellulose, or polylactic acid (PLA), not petroleum-based polymers.
Industrial composting facilities provide the heat, moisture, and microbes needed for full decomposition.
In contrast, conventional plastics persist for centuries because microbes cannot recognize their molecular bonds.
Home compostable versions exist but require consistent warmth and humidity—not all backyard bins suffice.
Labels like 'compostable' don’t guarantee breakdown in oceans or landfills, where oxygen is limited.
Some bioplastics still release microplastics if degraded incompletely, raising ongoing research questions.
Manufacturers aim to balance durability during use with safe end-of-life behavior for circular economy goals.

Some bioplastics still release microplastics if degraded incompletely, raising ongoing research questions. 部分生物塑料若未完全降解，仍会释放微塑料，引发持续研究关注。
They’re made from plant starches, cellulose, or polylactic acid (PLA), not petroleum-based polymers. 它们由植物淀粉、纤维素或聚乳酸（PLA）制成，而非石油基聚合物。
Industrial composting facilities provide the heat, moisture, and microbes needed for full decomposition. 工业堆肥设施提供充分分解所需的热量、湿度和微生物。
