Methane to Protein

Could you swap your steak for a protein converted from methane?

Turning greenhouse gases into food. Yes. That is possible.

String Bio are a company in the business of solving problems. With their award-winning blend of biology, chemistry, and engineering, String Bio are working to tackle both climate change and food scarcity.

With sustainable solutions across human and animal food, agriculture and emerging markets, String Bio’s claim to fame could be world changing; A proprietary fermentation process converting methane into a single-cell protein.

That protein could provide an alternative for both human and animal nutrition, with significant applications to agriculture. Reducing reliance on plant and animal proteins, driving sustainable outcomes.

In simple terms, we’re talking about turning greenhouse gases into food.

Game. Changing.

In the future, your burger might swap beef patties for a protein converted from methane

What impact could that have? Other than abating those greenhouse gases, of course.

Let’s look at the potential benefits in the animal nutrition world, for example.

To feed livestock and pets, 1.1bn tonnes of animal feed are produced yearly. The demand this puts on natural resources is significant. The feed industry uses 75% of the soy and 65% of the fish harvested globally to maintain its output.

The methane, converted to protein by String’s process, offers a sustainable replacement for animal macronutrients. Every member of the supply chain from animal, farmer, feed manufacturer and customer stand to benefit.

The potential is so high, WA based Woodside Energy has announced a US$9.9 million investment into String Bio. The intention is to explore the opportunities for String’s technology, and scale it up to commercial levels. All part of a Woodside target to spend $US5 billion on new energy products and lower-carbon services by 2030.

Woodside CEO Meg O’Neill said the company aimed to thrive through the energy transition with a resilient and diversified portfolio.

“Our investment in String Bio builds on our ability to potentially abate greenhouse gases through the conversion of carbon into useful products.

We believe String Bio’s technology could eventually be used to recycle methane at Woodside facilities. It could also be deployed at third-party sites with available biomethane such as landfill facilities and farms,” she said.

So, the question stands, would you eat protein that used to be methane?
