biodegradable
含义: Capable of being decomposed by bacteria or other living organisms, thereby avoiding pollution.
Biodegradable materials break down naturally into harmless substances through the action of microorganisms. The term is widely used in marketing and packaging to indicate environmental friendliness, though the speed and conditions of degradation vary enormously. Some materials labelled biodegradable only break down in industrial composting facilities, not in landfill or the ocean.
