EnvironmentalGeneralCommercial

Capable of being decomposed by bacteria or other living organisms.

Implies that the material breaks down into natural elements (water, carbon dioxide, biomass) under environmental conditions, though the timeframe and required conditions (e.g., industrial composting) can vary widely.

The story behind the word. Coined in the early 1960s as environmental awareness began to rise, this hybrid word combined the Greek root for life with the Latin root for stepping down. It was created to describe detergents that wouldn't leave permanent foam on rivers, and was later applied to plastics and packaging.

Word relationships

compostable: Compostable materials break down under specific, human-managed conditions into nutrient-rich soil, whereas biodegradable materials break down naturally via biological processes but may take longer or leave residues.
decomposable: Decomposable is a general term for anything that can rot, while biodegradable specifically highlights the role of living organisms (microbes) in the breakdown.

non-biodegradable: Materials, like traditional plastics, that cannot be broken down by biological organisms and persist in the environment for centuries.
persistent: In environmental science, persistent substances resist degradation and remain in the ecosystem indefinitely.

Commonly confused with

degradable: Degradable plastics can break down through physical or chemical processes (like sunlight or heat) into tiny microplastics, but they do not necessarily digest biologically like biodegradable materials.

Word family

biodegradability (noun): The capacity of a material to be decomposed by biological agents.
biodegrade (verb): To decay through biological action.

Collocations

biodegradable packaging
biodegradable plastic
biodegradable materials
fully biodegradable

Example sentences

"The company is committed to using biodegradable packaging materials made from cornstarch to minimize their long-term environmental footprint." Corporate sustainability report

Memory hook

Think of 'Bio' (nature) + 'Degrade' (break down) + 'Able' (can do). Nature is able to break it down. Biodegradable materials go back to the earth, giving nature a brand new birth.

When not to use

Do not use interchangeably with 'compostable' without checking; all compostable items are biodegradable, but not all biodegradable items are compostable in a home garden.

Fun facts

Some biodegradable plastics are made from polylactic acid (PLA), which is derived from fermented plant starch, usually from corn, cassava, or sugarcane.
