I've been involved in compost discussions in the gardening forums since 2002. That info graphic promotes the superstition and ignorance held over since the 1930s when Rodale first came to the public forefront. For example...

Dairy and eggs are the greenest greens you can put into compost short of meat. If you cannot create a hot compost pile in a few days, then skip the animal products, but for experienced composters, anything that was once alive should go into the compost. Disease and insect ridden plants should be composted because as the microbes process the diseased material, it will literally develop "antibodies" to the disease. Chemical pesticides should be composted simply to deactivate the pesticides. Pet waste is excellent in compost. The only reason not to is the "eiuuuuuu" factor. You decide but the graphic is wrong. If you don't compost pet waste you're wasting valuable nutrients. Black walnut? What? Superstition. Fats and grease take much longer to compost. I would suggest beginners leave this for much later when you are confident you can create a hot compost pile at will. You can compost coffee grounds, but coffee grounds are already a much better fertilizer than the resulting compost. If I was to move the list around, I'd take the sawdust and wood chips out of the compost simply because they will not decompose buried in compost. Wood dust and chips must be exposed to the air or they will just sit there. Vegetable waste and fruit scraps are not greens. With virtually zero nitrogen they are about as brown as you can get.

Compost is NOT worth $150 in fertilizer value. Compost is applied at a rate of 1 cubic yard per 1,000 square feet of garden. Cost for the compost ranges from $30 to the more reasonable $70 when delivered. The modern organic fertilizers are applied at 20 pounds per 1,000 square feet. Cost to cover the same 1,000 square feet is $5. And the fertilizer does a better job feeding the soil and plants. In my humble opinion compost is worth about 1/3 what organic fertilizer is worth.

Compost has its place in the garden but not as a fertilizer. I have had a compost pile for 12 years and wouldn't be without it.
