LanzaTech Global has announced its strategic expansion into the alternative protein sector, leveraging its proprietary carbon recycling technology. Known for converting industrial waste gases into useful products such as ethanol, LanzaTech now aims to use carbon dioxide (CO2) to create a new type of nutritional protein. This innovation, known as LanzaTech Nutritional Protein (LNP), positions the company as a key player in addressing growing global food demands while promoting sustainability.
The Need for Alternative Proteins
By 2050, the global population is expected to reach 10 billion people, driving the need for an additional 250 million metric tons of protein annually. Conventional protein production methods—whether plant-based like soy or animal-based like beef—place significant strain on land and water resources and can contribute to biodiversity loss. These traditional methods also face challenges like climate variability, which can disrupt food production.
In response to these issues, LanzaTech has developed LNP, a microbial protein derived from CO2. This nutrient-rich protein provides a sustainable alternative to conventional protein sources, using a fraction of the resources required for traditional agriculture. The production of LNP is not reliant on arable land or weather conditions, which makes it a reliable option for addressing global food security.
LanzaTech’s Biorefining Process and Technological Innovation
LanzaTech’s biorefining platform has been transforming carbon emissions from industries into valuable chemicals, fuels, and materials for years. Now, the company is extending this proven gas fermentation technology to produce LNP. This process involves the use of specially engineered microbes that consume CO2 to produce proteins with a complete amino acid profile—making them suitable for human consumption, animal feed, and other applications.
LanzaTech’s approach to protein production represents a shift from its previous focus on ethanol production. Historically, the company has used carbon-rich gases from industries to create ethanol, which serves as a feedstock for other chemicals or as a fuel. By refining this method, LanzaTech can now produce large quantities of protein while minimizing environmental impact. The company's technological development is rooted in nearly two decades of biorefining experience.
Commercialization and Market Potential
The alternative protein market is expected to reach $1 trillion as global demand for sustainable food sources rises. LanzaTech is positioning itself to capitalize on this growing market through its LNP production. The company has already been operating a pilot facility for two years, testing the feasibility of its technology at small scale.
Looking ahead, LanzaTech is in the engineering design phase for pre-commercial facilities expected to be operational by 2026. These sites will initially produce between 0.5 and 1.5 tons of LNP per day. Full commercial-scale production is planned for 2028, with facilities capable of producing over 30,000 metric tons annually. For context, producing 0.5 tons of LNP per day is equivalent to providing the recommended daily protein intake for approximately 9,000 people.
Environmental and Resource Efficiency
LNP production is designed to address the inefficiencies of traditional protein sources. Producing proteins from CO2 requires far fewer natural resources than conventional agriculture, making it a scalable solution that can mitigate environmental damage. In contrast to livestock farming, which contributes significantly to greenhouse gas emissions, LNP is produced using waste carbon, offering a circular approach to resource use. Furthermore, this method circumvents the need for large expanses of farmland or vast amounts of water.
Broad Application and Partnerships
The potential uses of LanzaTech’s LNP extend beyond human nutrition. The company is collaborating with the Center for Aquaculture Technologies to explore the protein's application in fish feed. Additionally, LanzaTech has partnered with Mattson, a food innovation firm, to test LNP in various consumer products, such as smoothies, dairy-free cheese, and bread. These trials are crucial for understanding the versatility of LNP in the food industry.
LanzaTech is also working with the U.S. Navy Research Laboratory to assess the feasibility of producing LNP on military platforms. This collaboration is part of a broader project to create sustainable food supplies for soldiers and sailors, especially in remote locations. Using CO2 extracted from seawater, the Navy hopes to develop a self-sustaining protein source for military operations.
Regulatory Pathway and Future Prospects
One of the key steps for LanzaTech’s LNP to reach the market is obtaining the U.S. Food and Drug Administration’s Generally Recognized as Safe (GRAS) certification. This regulatory approval will allow the company to expand LNP’s use in human food formulations. The GRAS certification process is underway, and its successful completion will open the door for LNP to enter the broader food market.
By 2028, LanzaTech plans to have large-scale LNP production facilities operational, capable of producing tens of thousands of metric tons annually. The company's expansion into the alternative protein sector not only diversifies its revenue streams but also positions it as a leader in sustainable food production. As the world seeks more resilient and environmentally friendly food sources, LanzaTech’s innovative approach offers a promising solution to future food security challenges.
LanzaTech’s expansion into nutritional protein production marks a significant step forward in both sustainable food technology and the broader effort to create a circular carbon economy. By leveraging its proven gas fermentation technology, the company is developing a cost-effective, environmentally friendly protein solution that can help meet the growing global demand for food. With commercial production expected within the next decade, LanzaTech is poised to play a crucial role in shaping the future of food security and sustainability.
This innovation not only reflects the company’s long-term vision but also represents a scalable solution to one of the most pressing challenges of the 21st century: feeding a growing global population without further straining natural resources.
