The Rise of Plant-Based Chicken: A Sustainable Future
Written on
Chapter 1: The Shift Towards Plant-Based Alternatives
As the popularity of plant-based foods surges, fast-food giants like Burger King are offering Impossible Whoppers, while Dunkin' has introduced the Beyond Sausage breakfast sandwich. Even McDonald's is tapping into the trend with its own line of plant-based products. The driving force behind this shift is the perception that meat derived from plants has a significantly smaller carbon footprint compared to traditional animal products. Companies leading the charge in alternative meats emphasize environmental sustainability as a core part of their marketing strategy. Pat Brown, CEO of Impossible Foods, has openly stated his ambition to capture a larger share of the beef market, aiming to push the conventional meat industry into a "death spiral."
However, the poultry sector isn't exempt from this transformation. Rebellyous Foods, founded by former Boeing engineer Christie Lagally, is focused on developing plant-based chicken products such as breaded tenders, patties, and nuggets—items that dominate the American poultry market. Lagally's assertion is clear: "We must reduce our reliance on chicken."
Chicken has become the most consumed meat in the U.S., accounting for nearly half of all meat consumption. In contrast, beef makes up less than 25%. The environmental impact of raising cattle is significant, requiring more water, land, and energy. While beef consumption has declined since its peak in 1976, chicken consumption has skyrocketed from 50 pounds per person in 1976 to 96 pounds in 2019. Each year, around 9 billion chickens are slaughtered in the U.S., far outpacing the 33 million cows that are processed annually. Despite this, beef often receives more scrutiny due to Americans consuming it at four times the global average.
"Chicken doesn't attract as much attention in environmental discussions because, on a per-pound basis, it generates fewer greenhouse gas emissions than beef," notes Lagally. "Nevertheless, we have to find ways to reduce chicken consumption."
Section 1.1: The Environmental Impact of Chicken Farming
Often overlooked in carbon discussions is the environmental toll of raising chicks. Rebellyous Foods aims to address this gap. The company has already launched plant-based chicken nuggets and is working on patties and tenders. The challenge lies in scaling up production to match conventional meat processing operations. Lagally emphasizes that the high cost of plant-based meat can be attributed to the industry's lack of industrialization.
"Our goal," she explains, "is to create production facilities that can operate at high volumes anywhere in the world, facilitating meat replacement."
In the broader context, animal agriculture is increasingly recognized as a major contributor to environmental degradation. The Intergovernmental Panel on Climate Change has identified a shift towards plant-based diets as essential in combating climate change.

Section 1.2: Transforming Production Processes
Lagally's vision for plant-based chicken production involves a technological breakthrough she refers to as "Mach One." By transitioning from a batch process to a continuous production model, she aims to make plant-based foods as affordable as their animal counterparts.
"To effectively replace meat, we need to industrialize plant-based production," she insists.
The environmental argument against livestock farming is gaining traction. The Food and Agriculture Organization of the United Nations reports that global beef production contributes an astounding 2.9 billion tons of greenhouse gases annually.
"You need to feed cows more than you get out in the end," explains Martin Heller, a research specialist at the University of Michigan, highlighting the inefficiencies in livestock farming.
Raising chickens generates approximately 360 million tons of greenhouse gases each year, equivalent to the weight of 6 billion coffee bags. While chicken is often marketed as a more eco-friendly alternative to beef, the inefficiencies in feed conversion persist.
Subsection 1.2.1: The Dangers of Poultry Farming
The waste generated by chicken farming typically re-enters cropland as fertilizer, leading to air pollution and nitrogen runoff that contaminates waterways. For instance, in 2018, a significant portion of nitrogen pollution from Pennsylvania's poultry operations flowed into the Chesapeake Bay, causing harmful algal blooms detrimental to aquatic ecosystems.
Chapter 2: The Path Forward for Rebellyous Foods
Christie Lagally's journey from leading a Boeing engineering team to founding Rebellyous Foods marks a significant career shift. Her engineering background provides a solid foundation for her new venture. While working at Boeing, Lagally began volunteering with the Good Food Institute, a nonprofit focused on promoting sustainable food alternatives.
"I felt compelled to make agriculture less polluting and more humane," she reflects.
Research indicates that plant-based meats have a lower environmental impact than traditional animal products. While the ingredients for animal feed and plant-based meats are similar, the latter requires less overall input, leading to a smaller carbon footprint.
"Plant-based components in both systems are comparable, but the animal system demands much more plant input," Heller observes.
When researchers evaluated the life cycles of meat substitutes, they found that plant-based products generate significantly fewer greenhouse gas emissions. For instance, a four-ounce Beyond Meat burger patty produces lower emissions than a beef patty. Data from Morningstar Farms confirms that their veggie chicken products emit less than their animal counterparts.
"Reducing emissions is crucial, but we must also consider more effective strategies to achieve this goal," says Robin White, a professor at Virginia Tech.
Lagally is determined to prove that plant-based meats can compete with traditional options in both taste and price. She is set to release an updated plant-based nugget, alongside a tender and patty, all designed to match the quality of popular chicken products.

Lagally is optimistic about the future, noting that the growing popularity of plant-based options signals a shift in consumer preferences. The success of limited-time offerings, like the plant-based chicken at KFC, reinforces her belief in the market's potential.
"Plant-based meats need to be cheaper and as tasty as the real thing to succeed," Lagally concludes.
