Australia together with most developed countries produces large amounts of organic food wastes, much of which is disposed of in landfills. The research undertaken in this project considered taking such organic wastes, and converting them to food-stuffs, through the process of vermiculture, hydroponics and aquaculture – the worms acting upon the wastes, the washed vermiliquer from the worm pits used as nutrients for hydroponics, and surplus worms fed to fish.
This RIRDC research demonstrated that such a system of food production is feasible, using either composted paunch (rumen) material from an abattoir or green wastes from an institutional kitchen, resulting in excellent production of the Asian vegetable species Pak Choi and good growth of the fish species Eel Tail Catfish, supplied respectively with fresh vermiliquer and worms.
The content of the report shows in some detail how organic wastes can be converted through vermiculture into resources that underpin the production of fresh horticultural produce and fish.
