The Plant is a new kind of organization in a very old building. It’s
part vertical farm, part food-business incubator, part research and
education space – and it will be entirely off the grid. Read on to learn
more about what we’re doing – and welcome!
What is The Plant? A Farm for the Future.
From its beginnings as a 93,500 s.f. meatpacking facility, The Plant is being repurposed into a net-zero energy vertical farm and food business operation. A complex and highly interrelated system, one-third of The Plant will hold aquaponic growing systems and the other two-thirds will incubate sustainable food businesses by offering low rent, low energy costs, and a licensed shared kitchen. The Plant will create 125 jobs in Chicago’s economically distressed Back of the Yards neighborhood – but, remarkably, these jobs will require no fossil fuel use. Instead, The Plant will eventually divert over 10,000 tons of food waste from landfills each year to meet all of its heat and power needs.
A Net-Zero Energy System
Funded in part by $1.5 million in grant money from the Illinois
Department of Commerce and Economic Opportunity, The Plant will install
an anaerobic digester and a combined heat and power system to operate
completely off the grid. By 2015, the completely enclosed, odorless
anaerobic digester will consume 27 tons of food waste a day (~10,000
tons annually), including all of the waste produced in the facility and
by neighboring food manufacturers. The digester will capture all of the
methane from that waste, and the methane will be burned in a combined
heat and power system to produce 400 kWh of electricity, plus all the
process heat needed for New Chicago Beer Company’s 12,000 sq. ft.
brewery. Excess heat will be used in an absorption chiller to regulate
the building’s temperature. The Plant will also be energy efficient:
while the building is already heavily insulated, we are improving the
efficiency of existing mechanicals using recycled and locally
manufactured materials.
Growing Vegetables with Fish
Recycling will also take place in the aquaponic farm systems.
Aquaponics is a closed-loop growing system that creates a symbiotic
relationship between tilapia and vegetables. The tilapia produce
ammonia-based waste that is sent through a biofilter where solids settle
out and the rest is broken down into nitrates. Those nitrates are then
fed to plants growing in hydroponic beds. By absorbing the nitrates, the
plants clean the water, which is returned to the fish. The Plant will
sell both the fish and the vegetables to local food markets and
restaurants, and will do so at a profit.
