Coal - It's what's for dinner!

1. The how

The CAS team's process works something like this: firstly, coal is transformed into methanol via gasification – a technique that can now be executed with near-zero carbon emissions. That methanol is then fed to a special strain of Pichia pastoris yeast, which ferments the methanol to produce a single-cell protein complete with a range of amino acids, vitamins, inorganic salts, fats and carbohydrates. The resulting organism is much richer in protein than plants are, and it can be used to partially replace fish, soybeans, meat and skimmed milk in a range of animal feeds.
