Green waste materials are going to provide nitrogen for the Decomposers in your compost pile. Here's a short list of good sources of green waste material:

Grass clippings that haven’t been treated with chemicals

Yard trimmings

Lawn and garden weeds without seeds

Fruit and vegetable scraps

Kitchen waste (such as egg shells, peelings and plant residues)

Flowers

Coffee grounds

Farm animal manure

Hair - In a family full of girls, we provide a LOT of hair into our compost pile.

As you can see, there's a lot of options for green waste materials. The main thing is to try not to include items that have been treated with chemical or have seeds that will spread and sprout into your compost pile.

Let's talk about the Brown Waste Material next.
