Engineering Biology for a Sustainable Future
Imagine a world where jet fuel is brewed from plant waste, plastics are derived from sugar and fully biodegradable, and critical medicines are produced by engineered microbes in vast fermentation tanks.
Explore the FutureThis isn't science fiction; it's the reality being built today through industrial biomanufacturing. This rapidly growing field stands at the forefront of a global shift towards more sustainable and bio-based production methods, promising to redefine how we create the materials, chemicals, and energy that power our world 1 .
At its core, industrial biomanufacturing is the use of biological systems—such as microbes, plant cells, or animal cells—to produce commercially valuable biomolecules 1 . By harnessing and engineering the innate power of living organisms, scientists are learning to build a bioeconomy, an economic model centered on renewable biological resources from agriculture, forestry, and fisheries 6 .
"This emerging model aims to produce a broad range of products, from food and materials to chemicals and bioenergy, offering a more sustainable and circular alternative to fossil-based systems."
Modern biomanufacturing is powered by advanced technologies that accelerate biological engineering
The engine of this new bioeconomy is white biotechnology, also known as industrial biotechnology. This involves using engineered biological systems, typically microbial cell factories like bacteria, yeast, or fungi, for the industrial production of chemicals, materials, and fuels 6 .
The goal is to deliver sustainable, scalable alternatives to petroleum-based processes, offering advantages like lower energy consumption, reduced greenhouse gas emissions, and the creation of biodegradable materials 6 .
The heart of biomanufacturing is the fermentation tank. Innovations in fermentation, including continuous manufacturing and high-throughput screening, are making production processes more scalable and cost-effective 1 .
The TOGLE Project: A Case Study in Innovation
To understand how these concepts come together in a real-world experiment, consider a groundbreaking project underway in 2025. ATCC, a premier biological materials organization, has entered a contract with Capra Biosciences to work on the DARPA Switch program, a strategic initiative to bolster U.S. bioeconomic security 9 .
The challenge is clear: the U.S. Department of Defense relies on petrochemicals for everything from fuels to textiles, creating dependence on vulnerable global supply chains 9 . The goal of the project, named TOGLE (Transcriptomics and OptoGenetics for Lipid Expression), is to engineer a single organism that can flexibly consume a wide variety of feedstocks to synthesize free fatty acids, which are precursors for synthetic aviation fuel and lubricants 9 .
The team selected the yeast Yarrowia lipolytica as their microbial chassis. This yeast is known for its versatility, robustness, and natural ability to handle diverse industrial conditions 9 .
The experimental procedure follows a multi-stage, iterative design:
| Reagent/Tool | Function in the Experiment |
|---|---|
| Yarrowia lipolytica | A robust species of yeast used as the base "chassis" organism to be genetically engineered. |
| ATCC Microbial Library | A comprehensive collection of authenticated microbial strains used to discover genes for feedstock metabolism. |
| Transcriptomics Tools | Computational methods to analyze gene expression data and identify genes active during feedstock consumption. |
| Optogenetics System | A technology using light to control cellular processes, potentially enabling real-time switching of metabolic pathways. |
| Modular Bioreactor | The production environment where the engineered yeast is tested for its ability to switch between feedstocks and produce target molecules. |
While the project is ongoing, its success will be measured by creating a fully functional yeast strain that can dynamically switch feedstocks to efficiently produce free fatty acids 9 . The scientific importance is profound. This project moves beyond optimizing for a single, high-yield product and instead focuses on creating a flexible, resilient, and opportunistic biomanufacturing platform 9 .
This directly supports national security and economic resilience by enabling the production of crucial commodities without relying on long, fragile petrochemical supply chains. As ATCC's Rebecca Bradford stated, this collaboration is about "driving innovation in industrial biomanufacturing" and "catalyzing growth in the U.S. bioeconomy" 9 . The base strains developed will also be made available to the wider scientific community, fostering further innovation 9 .

Despite its immense promise, the path to a bio-based future is not without obstacles
Navigating approval pathways for new bio-based products and genetically modified organisms can be prolonged and uncertain, driving some companies to seek regulatory paths outside the U.S. 2 .
While large firms thrive, smaller biotechs often face hurdles in securing consistent funding for expensive research and scaling operations 2 .
Developing advanced bioprocesses is extraordinarily expensive, with rising regulatory demands amplifying capital risk 2 .
Operating these complex technologies demands a skilled workforce fluent in AI, engineering, and regulatory science, which is in short supply 2 .
The momentum behind industrial biomanufacturing is undeniable
The global biotech market is estimated at $1.744 trillion in 2025 and is projected to rise to over $5 trillion by 2034 2 . This growth will be fueled by continuous innovation.
Emerging trends include the rise of cell-free systems, where biochemical reactions happen without living cells, and the development of "living intelligence systems" that combine biological sensing with computing for dynamic environmental responses 1 2 .
Investment in foundational infrastructure is also accelerating. Facilities like the ExFAB BioFoundry at UC Santa Barbara, opened in 2025, are equipped with state-of-the-art automation and robotics to "speed up the pace of biology" and build a workforce fluent in these transformative technologies 7 .
Industrial biomanufacturing represents a fundamental shift in our relationship with production. It moves us from extracting and processing finite geological resources to cultivating and harnessing boundless biological capabilities.
While challenges around regulation, cost, and scale remain, the trajectory is clear. By programming the inner workings of cells, we are building a more resilient, sustainable, and efficient future—one where the chemicals, materials, and fuels we depend on are grown, not solely mined.
This is not just the future of chemical production; it is a critical step toward a circular bioeconomy, promising to reshape our world from the molecule up.
