One of the winners of the 2016 Presidential Green Chemistry Challenge Awards was a process to generate dodecanedioic acid (DDA), a chemical used in making certain nylons. The older process uses chemicals from fossil fuels, uses nitric acid, and produces a greenhouse gas, dinitrogen monoxide. This process also requires high temperatures and pressures. The new process uses a modified yeast strain to manufacture DDA from an acid derived from palm kernel oil or coconut oil, is run near room temperature and pressure, avoids the use of nitric acid, does not generate dinitrogen monoxide, and leads to a higher purity product. Which principles of green chemistry are being followed by this new process compared to the older process?
