We are reaching the limits of how we make things.<br>For over a century, industry has relied on heat, chemicals, and fossil fuels. But what if we could manufacture materials the same way we brew beer?<br>Thanks for reading! Subscribe for free to receive new posts and support my work.

That is the promise of biomanufacturing. By treating biology as an engineering discipline, scientists are programming cells to produce chemicals, medicines, foods, and materials more efficiently—and sometimes create entirely new ones.<br>This shift is already underway. McKinsey estimates the bioeconomy could generate up to $4 trillion in annual economic impact, and the rapid scale-up of mRNA vaccines showed what biological manufacturing can achieve.<br>But scaling biology is hard.<br>Moving an engineered microbe from a lab bench to a 100,000-liter bioreactor remains one of the toughest challenges in modern engineering. The industry faces major bottlenecks in fermentation capacity, and many highly funded startups have failed to make the economics work.<br>To understand where biomanufacturing is actually headed, we need to look beyond the hype and examine the science, economics, and infrastructure driving the field.<br>In this deep dive, we’ll cover:<br>• How humanity evolved from ancient fermentation to modern synthetic biology.<br>• Why fermentation is only one piece of the biomanufacturing landscape, alongside pharming and chemoenzymatic processes.<br>• The lessons of the 2010s biofuels boom and bust.<br>• The companies turning biological manufacturing into products people can buy today.<br>\(\begin{array}{ll}<br>\text{Table of Contents} & \\<br>\hline \\<br>\mathbf{01} & \text{History & Origins} \\<br>\mathbf{02} & \text{How it works} \\<br>\mathbf{03} & \text{Past Failures} \\<br>\mathbf{04} & \text{Industry Innovators} \\<br>\mathbf{06} & \text{Future Outlook} \\<br>\mathbf{07} & \text{Conclusion}<br>\end{array}\)
How we got to modern biomanufacturing
Long before humans understood the concept of a cell, let alone DNA, we were already running biomanufacturing plants.<br>Every time an ancient civilization brewed beer, baked leavened bread, or fermented cheese, they were using living organisms as biological factories.<br>We can consider this the 0th stage of biomanufacturing.
The transition from kitchen craft to industrial science began in the late 19th and early 20th centuries.<br>Louis Pasteur demonstrated that fermentation was caused by living microbes, not chemical decay. This shifted the industry from guesswork to controlled microbiology.
during the 1940s, scientists realized they could use fermentation to produce penicillin and acetone, driven by huge demand, these were the first industrial scale bioreactors (basically tanks filled with bacteria)<br>This design choice still influences modern biomanufacturing (not always in a good way)
This was the 1st phase of biomanufacturing.
The real paradigm shift occurred in 1973, when Herbert Boyer and Stanley Cohen successfully transferred a gene from one bacterium to another, inventing recombinant DNA technology .<br>In 1978, Genentech used this breakthrough to produce synthetic human insulin. Before this, insulin had to be painstakingly extracted from the pancreas glands of millions of slaughtered pigs and cows, which frequently caused allergic reactions in patients. By turning bacteria into insulin factories, Genentech proved that programmed biology could outscale and outperform traditional chemical and agricultural extraction. Again, using bioreactors to grow and produce the insulin.<br>We can consider this phase the 2nd phase of biomanufacturing.
We are now entering the 3rd jump, which is very similar to how computing exploded in the 80s and 90s. This phase started roughly 20 years ago, Technologies critical to biomanufacturing will collapse, and the cost curve for starting a biomanufacturing company will rapidly slope downwards.<br>At the same time, we will shift away from big steel tanks to alternative hardware for manufacturing. In this phase biomanufacturing will explode from a method used to make niche products, to a broad manufacturing method.<br>How the 3rd generation of biomanufacturing will work
the third generation of biomanufacturing will ultimately have 2 major characteristics.<br>it will be accelerated by crashing costs for biotech
it will involve a diversification of the manufacturing hardware away from big tanks
In this section we will look at which technologies are reducing in cost and how it will help, and what will be used in replacement of traditional bioreactors.<br>cost curves
AI driven design
Lets imagine you are attempting to manufacture chemical A, and so you are trying to find a protein B that will stick to the precursor of Chemical A (we will call this precursor...
