Re-Nuble has cracked the code on how to help soilless farms grow their net income by going 100% closed loop, through the utilization of food waste. Over the past 5 years, the company has developed technologies that unlock water soluble nitrates from plant-based food waste streams, producing industrial-grade organic fertilizer for soilless farms.
The business of food production has produced enormous food waste in its wake. 20.2 million tons in the USA alone go unharvested each year, often left to rot or sent to landfills where valuable nutrients are locked away from ever hoping to rejoin the ecosystem. Re-Nuble’s goal is to reintegrate food waste as an industrial grade, closed loop fertilizer that is both price and yield competitive with the standard synthetic fertilizers for soilless farms. Their fertilizers are shown, on a grow cost per plant basis, to be 2X more cost effective than the current dominant market standard, mineral salts.
Re-Nuble selects a proprietary mix of food waste streams which are then processed using similarly proprietary methods in order to kill any pathogens. The food waste is then prepared to become a plug-and-play fertilizer. Re-Nuble funnels this fertilizer through their patent-pending Nutrient Delivery System, an on-site hardware technology suite that rapidly solubilizes provided fertilizers, monitors pH levels, manages EC control, and ensures the long-term recirculation of the same nutrient-rich water for years to come. Part of this technology is available immediately to solubilize products, and the full suite will be available in early 2021.
As an added value, the company also offers client waste integration through an on-site hardware technology suite. The client’s own food waste stream is used as input and converted into a yield-enhancing fertilizer supplement. This enables farms to decrease water loss, enhance food supply chain security, and further decrease their operation’s GHG emissions. This has been of particular interest to farms operating at least 4 acres of production space.
It is Re-Nuble’s philosophy to mirror the processes of our natural food ecosystem, infinitely more complex than human-built food production methods that have hundreds, if not thousands, of discrete, often-invisible ways to re-integrate food waste back into nature. Wind and birds carrying seeds, small mammals burying acorns, yeast protecting the outer layers of fruits for longevity, and so on. Closing the loop on food production is an attempt to industrialize this natural re-integration process. The benefits include net income growth, emission reduction, and enhanced food security.
