Dairy and tofu waste can become powerful carbon traps, Swiss scientists find
Protein-rich waste liquid from tofu or dairy production could be made into beads that capture carbon dioxide from the atmosphere, researchers have found. Researchers at ETH Zurich extracted proteins from dairy waste byproducts and combined them with potassium hydroxide in an elaborate process to produce porous beads. Protein-rich liquid is generated during dairy and tofu production.
