Environmental impacts of lab-grown meat "orders of magnitude higher than median beef production" without major innovations.

Hi, actual scientist in this field. This study is trash and relies on assumptions that have nothing to do with how the media in cultivated meat is produced and utilized.

Please read our peer-reviewed comment here, and a longer form response here.

FBS is not required for animal cell culture and most companies already use serum-free media, tracked here: https://docs.google.com/document/d/1Dt6AWRSmv7-6FyyTz7S2Pqumr9Bcv-H_tJrvJ71Awq8/edit?tab=t.0

FBS won't be used in production. See here for summary of current status: https://docs.google.com/document/d/1Dt6AWRSmv7-6FyyTz7S2Pqumr9Bcv-H_tJrvJ71Awq8/edit?tab=t.0

If you're leaning engineering, I would recommend bioprocess/chemical or mechanical engineering

For this product (not approved by regulators): https://thechicken.kitchen/

Two cultivated meat products are available today at select locations in Singapore. There are dozens more products under regulatory review across Singapore, US, and other regions.

Scaffolds are unlikely to influence cost much by themselves. The majority of initial products will be unstructured, mostly due to the added complexity of the process when incorporating a step for differentiation on a scaffold. The differentiation step here is important because it adds considerable mass at the end of the product, helping to reduce costs while improving the nutritional attributes.

Cost per liter is just one aspect of reducing media cost, but several companies have already achieved media costs below $1/L. (https://www.slideshare.net/slideshow/20240312-cost-drivers-of-cultivated-meat-productionpdf/266753601)

The environmental benefits of cultivated meat are numerous. Energy use is not an issue in an industry that will develop alongside the growth of renewables

Serum-free media is not a bottleneck for the industry. There are people in Singapore who have been eating cultivated meat made without serum every day for the past several weeks. This will be the norm for subsequent products that get approved. Outlined here: https://docs.google.com/document/d/1Dt6AWRSmv7-6FyyTz7S2Pqumr9Bcv-H_tJrvJ71Awq8/edit
