How Artificial Shrimps Could Change the World (economist.com) 102

Posted by BeauHD from the environmental-destruction dept.
Singaporean company Shiok Meats aims to grow artificial shrimp to combat the negative environmental effects associated with farmed shrimp. An anonymous reader shares an excerpt from The Economist: For a long time, beef has been a target of environmentalists because of cattle farming's contribution to global warming. But what about humble shrimp and prawns? They may seem, well, shrimpy when compared with cows, but it turns out the tasty decapods are just as big an environmental problem. The issue is not so much their life cycle: shrimp (as UN statisticians refer to all commonly eaten species collectively) do not belch planet-cooking methane the way cows do. But shrimp farms tend to occupy coastal land that used to be covered in mangroves. Draining mangrove swamps to make way for aquaculture is even more harmful to the atmosphere than felling rainforest to provide pasture for cattle. A study conducted in 2017 by CIFOR, a research institute, found that in both these instances, by far the biggest contribution to the carbon footprint of the resulting beef or shrimp came from the clearing of the land. As a result, CIFOR concluded, a kilo of farmed shrimp was responsible for almost four times the greenhouse-gas emissions of a kilo of beef. Eating a surf-and-turf dinner of prawn cocktail and steak, the study warned, can be more polluting than driving across America in a petrol-fuelled car.

All this has given one Singaporean company a brain wave. "Farmed shrimps are often bred in overcrowded conditions and literally swimming in sewage water. We want to disrupt that -- to empower farmers with technology that is cleaner and more efficient," says Sandhya Sriram, one of the founders of Shiok Meats. The firm aims to grow artificial shrimp, much as some Western firms are seeking to create beef without cows. The process involves propagating shrimp cells in a nutrient-rich solution. Ms Sriram likens it to a brewery, disdaining the phrase "lab-grown." Since prawn-meat has a simpler structure than beef, it should be easier to replicate in this way. Moreover, shrimp is eaten in lots of forms and textures: whole, minced, as a paste and so on. The firm is already making shrimp mince which it has tested in Chinese dumplings. It hopes the by-product of the meat-growing can be used as a flavoring for prawn crackers and instant noodles. Eventually it plans to grow curved "whole" shrimp -- without the head and shell, that is. While producing shrimp this way currently costs $5,000 a kilo, Shiok Meats thinks it can bring the price down dramatically by using less rarefied ingredients in its growing solution.

      Sure at 60 Euro / KG or roughly $30/pound. Non-sustainably sourced shrimp cost roughly $7-$20 per pound depending on size grade.

      This is the challenge of sustainable agriculture (or in this case aquaculture). I can buy locally sourced, grass fed beef but it's roughly 2x as expensive as grain finished beef shipped across the country. That's actually close enough that there's a market niche for providers, people who will pay a premium for artisinally produced meat. The existence of a market for artisinal beef is not a viable solution to the environmental problems of cattle farming.

      This new process is unlikely to be more efficient at the outset to be competitive in the general market than aquaculture, but there may be an "impossible meat" type market niche. To become a market-driven solution to the general environmental problems of shrimp aquaculture, it would have to be scaled to the point where it is at least comparably efficient from a financial point of view.

        I guess it depends on your locale... I'm eating free-range, grass fed beef sourced directly from a local producer controlling the entire meat lifecycle (from birth to the counter) and they beat supermarket meat prices (3 euro/kg cheaper for filet, 5 euro/kg cheaper for rumsteak, 4 eur/kg for rib steak).
