nonchemical
Free of substances
Nonchemical describes methods, treatments, or approaches that don't rely on synthetic chemicals or pesticides.
The term appears most often in contexts of pest control, agriculture, and cleaning: nonchemical weed removal, nonchemical alternatives to traditional pesticides.
Since technically everything is made of chemicals, the word really means without added artificial or industrial compounds.
