how to make seafood waste material as fertilizer & removing any plant harmful salts #321692

Asked May 15, 2016, 4:11 AM EDT

I would like to know how to best utilize waste sea scallops/shrimps complete with clam like shells, prawn/shrimp & unwanted offal & damaged fleshy bits.As all these materials complete with seawater are combined in the disposed waste, I need to know how to best prepare this waste into a usable fertilizer and not have any  salts in the finished product that will harm the plants when applied.
I am open to a dry or wet end product.
There is a heat treatment method for an end dry product & some wet treatments.
Do either display more benefits for better plant growth?
Currently the quantity I have access to in its raw state is equivalent to approx 4-6 tonnes per week.
I am in Australia.
Also can I bulk it up with other materials to end up with more of the final product to sell?
