Cow-free burger hits MITs “Top 10 Breakthrough Technologies” List

MIT Technology Review annually makes their “Top 10 Breakthrough Technologies List”. This year, “Cow-Free Burgers” make it to their list, alongside a carbon dioxide catcher and developments in health and medicine.

Read the exerpt below about the revolutionary burgers, or read the whole article here.

The cow-free burger

Both lab-grown and plant-based alternatives approximate the taste and nutritional value of real meat without the environmental devastation.

  • Why it matters: Livestock production causes catastrophic deforestation, water pollution, and greenhouse-gas emissions
  • Key players: Beyond Meat
    Impossible Foods
  • Availability: Plant-based now; lab-grown around 2020

The UN expects the world to have 9.8 billion people by 2050. And those people are getting richer. Neither trend bodes well for climate change—especially because as people escape poverty, they tend to eat more meat.

By that date, according to the predictions, humans will consume 70% more meat than they did in 2005. And it turns out that raising animals for human consumption is among the worst things we do to the environment.

Depending on the animal, producing a pound of meat protein with Western industrialized methods requires 4 to 25 times more water, 6 to 17 times more land, and 6 to 20 times more fossil fuels than producing a pound of plant protein. 
The problem is that people aren’t likely to stop eating meat anytime soon. Which means lab-grown and plant-based alternatives might be the best way to limit the destruction.

Making lab-grown meat involves extracting muscle tissue from animals and growing it in bioreactors. The end product looks much like what you’d get from an animal, although researchers are still working on the taste. Researchers at Maastricht University in the Netherlands, who are working to produce lab-grown meat at scale, believe that by next year a lab-grown burger could cost no more than a hamburger made from a cow. One drawback of lab-grown meat is that the environmental benefits are still sketchy at best—a recent World Economic Forum report says the emissions from lab-grown meat would be only around 7% less than emissions from beef production.

The better environmental case can be made for plant-based meats from companies like Beyond Meat and Impossible Foods (Bill Gates is an investor in both companies), which use pea proteins, soy, wheat, potatoes, and plant oils to mimic the texture and taste of animal meat.

Beyond Meat has a new 26,000-square-foot (2,400-square-meter) plant in California and has already sold upwards of 25 million burgers from 30,000 stores and restaurants. According to an analysis by the Center for Sustainable Systems at the University of Michigan, a Beyond Meat patty would probably generate 90% less in greenhouse-gas emissions than a conventional burger made from a cow. —Markkus Rovito
