Lab-Grown Alternatives Aim To Cut Palm Oil Dependence

An anonymous reader quotes a report from the BBC: It was landing at Singapore's international airport a decade ago that sparked Shara Ticku's idea to create a lab-grown alternative to palm oil. "In 2013 I flew to Singapore, and when I landed I had to wear a mask," says the boss of US tech firm C16 Biosciences. "The air was toxic because they were burning the rainforest in Indonesia." Indonesian farmers, who were clearing land for palm oil and other crops, were blamed for the fires and the smoke that drifted across the sea to Singapore. Fast forward to today, and her business has just commercially released an alternative to palm oil that is created from yeast cells. Palm oil remains the world's most-produced vegetable oil, accounting for 40% of the total, according to the World Wide Fund for Nature (WWF). [...] The widely-documented problem with this usage is that this demand for palm oil has led to significant deforestation in areas where oil palm trees can grow -- low-lying, hot, wet areas near the equator. The use of this land for palm oil cultivation, 85% of which is in Indonesia and Malaysia, has increased almost nine-fold from 3.3 million hectares (eight million acres) in 1970 to 28.7 million hectares in 2020. In financial terms, one report valued the worldwide palm oil industry at $62.3 billion in 2021. And such is the continuing growth in demand, this figure is expected to increase to $75.7 billion by 2028. To try to reduce the world's reliance on palm oil, Ms Ticku, who was formerly an investment banker, and her co-founders set up C16 Biosciences in New York City in 2018. Backed by multi-million dollar funding from Microsoft founder Bill Gates, the company has spent the past four years developing and finessing their product, which is called Palmless. They grow a strain of yeast that naturally produces an oil with very similar properties to palm, which they harvest. The yeast is fed on sugars from sugar cane plants grown on land already used for arable farming. "Our process takes less than seven days from start to finish," says a spokeswoman for C16 Biosciences. "For a traditional oil palm tree, the oil wouldn't be ready to harvest until years after the seed is planted, and most trees don't reach peak production until seven years later." She adds that the company is now "actively collaborating on partnerships in the beauty and home categories -- for example, moisturizers, nourishing oils, soaps and cancels". "[And] we plan to enter into food in 2024." Chris Chuck, professor of bioprocess engineering at the University of Bath, leads another team that has created its own yeast-sourced alternative. "After hundreds of generations of yeast, and years of trial and error, they arrived at a unique strain called metschnikowia pulcherrima, or MP for short," reports the BBC. "MP is said to be hardy and not fussy what it eats. It can be fed on grass and food waste. And at the point of harvesting, its cells are full of oil. Even the leftover yeast cell biomass need not go to waste. It can be used for other products, for example creating a substitute for soya protein." Prof Chuck says the aim is for the oil to be as sustainable as possible. "In the best case scenarios we've modeled," he says, "it could be even just a couple of percent of the greenhouse gas emissions from palm oil grown in Indonesia or Malaysia."
