Scale-up economics for cultured meat

Area of Science:

• Biotechnology and Food Science
• Industrial Fermentation
• Biopharmaceutical Manufacturing

Background:

• Cultured meat, derived from animal cell culture, presents a potential alternative to conventional meat production.
• Scalability of cultured meat hinges on efficient and cost-effective animal cell production.

Purpose of the Study:

• To assess the technoeconomic feasibility of scaling animal cell culture for mass production.
• To identify key limitations and cost drivers in cultured meat production.

Main Methods:

• Technoeconomic analysis applied to industrial fermentation and biopharmaceutical processes.
• Evaluation of factors limiting bioreactor scale and cell density.
• Analysis of capital and operating costs for conceptual cell-mass production facilities.

Main Results:

• Low cell growth rates, metabolic inefficiencies, and shear sensitivity limit bioreactor performance.
• High capital costs for sterile equipment and expensive growth media components.
• Projected production costs likely make cultured meat unaffordable as a food source.

Conclusions:

• Significant metabolic efficiency improvements are required for cultured meat production.
• Development of low-cost media, potentially from plant hydrolysates, is crucial but insufficient alone.
• Current economic and technical barriers suggest cultured meat is unlikely to displace conventional meat without substantial innovation.
