shellfish and compost
Submitted by Griffo84 on Sat, 2013-12-07 08:09
good morning ladies and gents,
Just wondering if anyone knows if prawn shell and crab shell is any good for the compost bin? I have heard it's no good - even toxic for your compost. I managed to catch a few blueys in Mandurah yesterday but dont want to throw all the shells in the compost just yet. - BTW it looks like its going to be a good season for the crabs. There are so so many crabs 2-3 mm under sized so around chrissy jobs on!!
Cheers

Shells
Read an article inserted below FYI
Shrimp shells can be problematic for the home composter, because as they decompose they generate an unpleasant odor that attracts pests. Simmer the shells for 20 to 30 minutes in boiling water, then drain them well and toast them until dry. Crush the brittle shells in a food processor, or with your rolling pin. The first step cooks out residual fats from the shells, minimizing odor, while crushing the dried shells to fragments helps speed decomposition by exposing more surface area to beneficial bacteria. (see Reference 1)
- Maybe more trouble than its worth !
Commercially they compost almost anything as the temperature gets really high 80 degrees C +. This reduces the "Odour Time" to a day or 2 after which the product, meat, dairy etc ends up like any compost.
I have started adding a bit of Horse manure to my compost and this has attracted heaps of Earthworms and there is no smell, so I am guessing this will speed up the composting process substantially.
Horse manure is available for free from some rising stables. They have so much that they want to get rid of.
Cheers

Or refeed next time your out
I freeze mine, but the soiled water from cleaning them goes on tomato plants, they love it. The shells etc then get recycled back into the water where they came from. Keeps the system going IMO.
