Palm oil grows best in the regions right around the equator, so palm oil producers chop down rainforest and clear that felled vegetation by burning it, making it a prime target of conservation organizations like the Rainforest Rescue and the World Wildlife Fund. Palm oil trees grow at the Cikasungka palm oil plantation, operated by PT Perkebunan Nusantara VIII, in Bogor Regency in West Java, Indonesia, on Monday, June 20, 2022. To make its palm oil alternative, C16 Biosciences uses a wild yeast microbe that makes a functional equivalent to palm oil with a kind of fermentation process.

However, "it contains the same fatty acids, which are the molecular fingerprints of fats and oils, that palm oil does," Heller told CNBC.
