Organic Farming Facility

This vision for an organic farming facility has 4 functions: Greenhouse, Livestock, Composting, and Mushrooms.  Only the Greenhouse functions requires sunlight, so the majority of this facility could conceivably be underground to promote geothermal regulation.

The first function is as a Greenhouse facility that requires open sunlight.  This could be any fashion of greenhouse, but a hybrid aquaponics/hydroponics facility has the most appeal and could interconnect with the other functions as well as being very efficient from a water usage perspective.  Outputs of this would be all manner of vegetables, herbs, spices, fruits, etc. as well as fish if aquaponics is leveraged.

The second function is as housing for some amount of Livestock.  Chickens (eggs) and sheep/goats (wool, milk) have the advantage of producing secondary products as well as meat.  Waste from this function is a primary input into the Composting function.  A primary source of food could be various forms of seaweed, which should be pretty easily produced along the coast or in sea channels.

The Composting function allows for the waste from other areas to be recycled and reused.  Composting would include the use of black soldier fly larvae, which serves to break down waste more quickly.  Excess larvae from this would be used as food for chickens in the Livestock area as well as fish in the Greenhouse facility.  Liquid output from composting (worm tea) could be used in the Greenhouse hydroponics area.  Both liquid and solid outputs could then be leveraged as fertilizer in additional agricultural ventures or sold.

 Mushrooms grow very well in compost and provide excellent nutritional value for both humans and livestock as well as being a potential commercial export.

Air circulation through the facility would be key.  Air would be moved from the Greenhouse/Mushroom functions, into the Livestock area to provide oxygen, and then into the Compost section.  After the Compost section, the air should be filtered, especially for ammonia and methane before being returned to the Greenhouse/Mushrooms areas with plenty of carbon dioxide to promote growth.  Ammonia could be dissolved in water and transferred into the Greenhouse to provide nutrients to the plants in the form of nitrates.  The methane could potentially be used as a fuel source to produce additional energy as needed.
