HISTORY The firstknown use of the word in biological text was in 1961 when employed to describe the breakdown of material into the base components of carbon, hydrogen, and oxygen by microorganisms . Now biodegradable is commonly associated with environmentally friendly products that are part of the earth’s innate cycle and capable of decomposing back into natural elements. 6 Etymology of "biodegradable“
