New York-based start up BrightFarms is to sell year-round ultra-local vegetables directly to US supermarkets by growing them in hydroponic greenhouses on the stores’ roofs.
BrightFarms’ rooftop hydroponic greenhouses offer high yield rates using 14 times less land and ten times less water than conventional farming methods. To further reduce carbon emissions, the greenhouses are warmed using waste heat from the supermarket’s refrigeration systems.
A staff of ten will oversee the production of 227 tonnes of seasonal produce per facility – including lettuces, tomatoes and leafy greens. Once ripe, vegetables will be put on shelves within 24 hours of being harvested.
