undegraded
Not broken down
Undegraded means not broken down, diminished, or reduced in quality.
The term appears most often in technical contexts: an undegraded signal retains its original strength, undegraded soil hasn't lost its nutrients, undegraded polymers haven't decomposed.
In environmental science, undegraded materials are those that haven't been broken down by natural processes: The plastic remained undegraded after decades in the landfill.
