Can You Compost Old Protein Powder?

Maybe a silly question, but I have pounds of this stuff that has been sitting around forever, and would like to do something useful with it. Can I compost it? Thanks!

I think it could be composted resulting in good compost. An orchardist might be interested in using whey in a nutritional and disease preventing foliar spray.

Easily, you might even consider it a compost activator. An expensive one but the protein will be quite the organism boost equal to hair and feathers.

Absolutely. Especially if you run it through a bokashi bucket first. I would personally feed it to my worms if it didn't have artificial dyes or flavors.

the earthworms would love it

Check with your local health food store for outdated protein powders. They throw these out when they are too old to sell. If no one at the store takes them, you might be able to take it for free (you can recycle the containers or use them to store stuff). Also check to see what they do with spoiled organic produce and cardboard boxes they receive shipments in...often this all goes in the trash too - but if you ask nice the manager might be willing to set it aside for you. Free is good! - and recycling is good for the planet.
