Re-Nuble Helps Soilless Farms Grow Net Income By Going Closed Loop
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
New York, NY | July 1, 2020
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. While others with the same vision have found themselves burdened with the obstacle of building an organic fertilizer that is both cost and yield-production competitive with synthetics, Re-Nuble has succeeded.
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.
From a net income perspective, Re-Nuble fertilizers are far more cost-effective than mineral salts and deliver a wider micronutrient and microbial profile. These fertilizers align with crop growth at the speed and year-round sowing or harvesting cycles of mineral salt-fertilized soilless farms. Since they are 2x more cost-effective than mineral salts, client farms receive immediate net income improvements. Furthermore, Re-Nuble’s fertilizers unlock organic food production that fetches a long-term, far greater
gross margin increase (at least 20% or more). Combined, the significant savings on the cost side and enhanced earnings enable client farms to become significantly more profitable and viable businesses.
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.

ABOUT RE-NUBLE
Re-Nuble is an agriculture technology company that uses organic cycling science to unlock the conversion of food waste into industrial-grade organic fertilizer for soilless farms. We are the world’s enabler of closed loop food, recirculating natural resources from participant waste streams and the greater food system. We divert the valuable resource of food waste from entering landfills, eliminating methane emissions that would have been circulating in our ecosystem. Through our pelletized fertilizer and proprietary “nutrient delivery system”, farms rapidly convert waste streams into soluble nitrates, amongst other nutrients, for quicker plant uptake and yields. The results are comparable to the nitrate availability of industry-dominant fertilizers, synthetic mineral salts, allowing farms to increase their bottom line. Our recirculating nutrient technology enables soilless farms to more competitively grow soil-quality, organic produce with sustainable best practices.

A New York City startup is using potato peels, apple cores, and rotten tomatoes to help farmers grow fresh fruits and vegetables.
“We take produce waste from food distributors and food processors – anything that can’t go to a food bank or farm,” says Tinia Pina, founder, and CEO of Re-Nuble.
The company converts food waste into organic fertilizer pellets that can be used in indoor, hydroponic farms.
Pina says when dissolved in water, the pellets make the nutrients immediately available to the plant, mimicking the biological nutrient systems found outdoors.
So she says the technology can help make it easier to grow organic food indoors in urban areas, where fresh local food is often scarce.
And it helps the climate. It keeps food out of landfills, where it would otherwise decompose and release methane, a potent greenhouse gas.
It also reduces the need for synthetic fertilizers, which create a lot of carbon pollution when they’re manufactured.
So far, the company has facilities in New York City and Rochester, New York, and plans to expand to the West Coast. Pina hopes to eventually help cities across the country use their food scraps to grow local, organic food.

This Urban Pop-Up Farm is Powered by Coffee Grounds
Melbourne roaster Cirrus Fine Coffee grows vegetables and herbs in a tiny garden, thanks to the help of coffee waste.

The pop-up farm on Cirrus Fine Coffee’s parking lot is a little green oasis in the industrial area of Port Melbourne.
“We have heritage varieties of tomatoes, corn, zucchini, pumpkin, spring onion, beetroot, rainbow chard, spinach, silverbeet, flowers to attract beneficial insects and also a range of herbs like chives, basil, oregano and coriander,” says Brendan Condon. And all of this only takes up two parking spaces.
Condon is the director of sister companies Cirrus Fine Coffee, Biofilta and Australian Ecosystems, which have collaborated to develop super-efficient compact pop-up farms. “We often think that we have overcrowded cities, but if you look at them from the lens of urban farming, we have huge amounts of space. We can flip cities into becoming super-efficient food growers,” he says.
These beans deliver more than a caffeine hit.
From landfill to compost
Each year, caffeine-loving Aussies produce around 75 000 tonnes of coffee waste, most of it ending up in landfill where it contributes to the production of methane, a greenhouse gas. But coffee grounds don’t have to end up there; they can be composted and used to produce food.
Cirrus Fine Coffee’s own pop-up garden uses a mix of composted coffee grounds (rich in minerals and nitrogen), husks from the roastery (a good source of carbon), food scraps and a small amount of manure, to help produce around 300 kilos of food per year. With the World Health Organisation recommending adults consume a minimum of 146 kilos of fresh fruits and veggies per year, it means that one of these pop-up farms could provide enough for two people for a whole year.
The Biofilta wicking (self-watering) garden beds are easy to install and low maintenance. The design holds enough liquid to water the garden for a week in summer and a month in winter.
“We want people to take advantage of the abundant resources for urban farming and to engage with it, so we improve nutrition and health, and divert waste from landfill,” says Condon.
Cirrus Fine Coffee is committed to sustainability in more ways than one. Its coffee beans are ethically sourced, the brand's packaging is biodegradable and its offices run on clean energy.
It's also partnered with Reground, an organisation that goes to cafes to pick up coffee grounds and transport them to community gardens and pop-up farms.
“We all need to work together,” says Ninna K. Larsen, founder of Reground. “We work at changing the system rather than just collecting coffee. Coffee is just a great conversation starter. It’s about getting people talking about what organic waste can do, instead of going to landfill. We can grow food with it.”
Condon would like to see cafes and people around Australia embrace urban farming. “If you have a cafe where you recycle coffee grounds to grow food, people will want to go there and support that business,” he says. “Hopefully, in a few years, it will be common practice.”
Growponics Wins EU Seal of Excellence For Developing Organic Fertilizer
Growponics’ R&D project for nitrogen fixation has been granted the Seal of Excellence and has passed Phase 1 of the EIC SME Instrument, with a grant of €50,000.

Growponics’ R&D project for nitrogen fixation has been granted the Seal of Excellence and has passed Phase 1 of the EIC SME Instrument, with a grant of €50,000. The SME Instrument is a part of the EU program Horizon 2020, aimed at small and medium sized enterprises (SMEs) with ground-breaking ideas and innovations.
Our project is focused on developing a process for the production of a sustainable organic hydroponic fertilizer, utilizing nitrogen fixed by cyanobacteria. Nitrogen is one of the key elements required for the growth of any living organism, used for the production of proteins. The majority of organisms cannot use nitrogen from the air. The few organisms who can perform this task, transform nitrogen from air into organic compounds (like ammonia and nitrates), that can be metabolized by the organisms who need it but cannot make these by themselves. Most plants cannot fix nitrogen, and this is why they rely on obtaining it through nutrients found in ground and water. Hydroponically grown plants rely on supplemented fixed nitrogen – fertilizers.
What kind of nitrogen fertilizers are available now?
Current synthetic fertilizers use nitrogen produced in the Haber process. This process requires a large amount of energy, and also emits undesired greenhouse gases. Organic fertilizers that are currently available are expensive, or their nitrogen is of low availability to plants, or they are high in sodium – all are disadvantages which prevent commercial use.
What is our project all about?
We are developing a method for production of nitrogen in-situ by cyanobacteria, from air and water, using the sun as a source of energy. The entire process is efficient and ecologically sustainable, and will allow hydroponic growers to provide their crops with the necessary nitrogen in an environmentally friendly way.
The grant of €50,000 awarded in Phase I will allow us to complete our feasibility study and prepare a business plan ready for scale up. We intend to proceed to Phase II (scale-up and commercial readiness) and Phase III (business acceleration). Hopefully, in ~3 years time we can be in the market with a commercial solution, to be used by our partner greenhouses and proceeding to other projects internationally.
