Check with your local health food store for outdated protein powders.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.
