Heritage Cases

Phase 1: Fish Production Greenies Farm aims to establish an agri-business through the development of aquaponics (a combination of aquaculture and hydroponics). Production will be based on Recirculating Aquaculture System (RAS). Water flows between aquaculture fish tanks and plant growing beds in a reticulated and closed system. The fish waste in the water is a key ingredient in the supplying of nutrients to the plant, enabling an unnecessary need for fertilizers, advancing organic fresh produce. The symbiotic relationship is such that fish waste provides nutrients, while the plants clean the water to remove all the harmful ammonia produced by the fish. Further supplements will be done such as aeration to ensure oxygen levels in the water. The facility will grow 100tons of Nile Tilapia and estimated 600tons of vegetables. The facility will have brick and mortar hatchery and nursery, grow-out greenhouse (2100 square meters), brick and mortar processing unit, office, ablution facilities, as well as duckweed greenhouse which is feed. Phase 2: Poultry The second phase of the project will consist of 4 broiler houses (each house to hold 50100 chickens) and 1 layer broiler (80 000 layer chickens). Piggery operation to hold 800 pigs. A snail greenhouse which will feed on green leafy offcuts from the vegetables grow-out. Heating will be initially from electricity and coal, with a standby diesel generator as backup. The plan is to later use methane from biodigester. Organic waste will be used in the following manner:  fish guts fed to Black Soldier Fly larvae that will feed on guts, and dried to be fed to fish, chicken and fish;  vegetable leaves to be fed snails, chicken, pigs and some as manure  fish, chicken and pig poop to be used for biodigester as well as Black Soldier Fly larvae
