nonbiologically

These organic compounds also originated early in the solar system's history, and are considered to have formed nonbiologically.

In a similar way as with synthetic alcohol production, hydrogen can be used on site to directly (nonbiologically) produce greenhouse-neutral gaseous fuels.

The term Bioconversion, also known as biotransformation refers to the use of live organisms often microorganisms to carry out a chemical reaction that is more costly or not feasible nonbiologically.
