Another Calculation
Sorry, I finally found some more information on the Alterrus system. There are 24 growing pots per tray. Each pot is ~ 142 grams (in terms of the microgreens/rooftop blend/vancouver special; as the salad blends are grown all together in one pot). And there are ~ 3000 trays in the rooftop system. Also it takes 18 -24 days for a growth cycle. So lets recalculate:
24 x 3000 trays = 72,000 products at a time. With 365/24 (to be conservative), we get ~15 cycles. So we get 72,000 x 15 = ~1.08 Million products. If each 142 gram product is sold ~ $2 per product, that gives a revenue of ~ $2.1 Million. This coincides with my initial calculation. If each product sells ~ $2.5 per package, then there is 0.5 Million more. Now if Vancouver's facility is able to achieve a large amount of demand, and expand their product to the second level, earnings will achieve $4 - 5 million a year. And I think that may not be too far off as they get the Epcot Center system built and potentially another system in Chicago and selling of a system in China. After another year of increasing revenue, they may be able to attract the necessary funding to expand their Vancouver facility (let alone use funds from a Chinese system to expand as well).
