When I first ventured into composting, I found that nut waste was one of the most difficult things to deal with. After some research, I found that chemically it can take 2 to 3 years for the shells to decompose. My recommendation would be to grind up the shells if you are adding them to your compost pile. They will still take time to break down, but it adds a nice bulk to your compost.
Decomposition of organic material in the compost pile depends on maintaining microbial activity. Any factor which slows or halts microbial growth also impedes the composting process. Efficient decomposition occurs if aeration, moisture, particle size, and a sufficient source of carbon and nitrogen are in evidence.
