Re-Nuble Aims to Use Food Waste To Make Indoor Agriculture More Sustainable

The role of indoor growing, ranging from small indoor vertical farms to large greenhouses, is vital to sustaining the world’s food supply. Controlled Environmental Agriculture is essential for growing crops in underused spaces, rooftops, and rows of vertical gardens. Seizing upon this vital resource, Tinia Pina, Founder & CEO of ReNuble, has taken up the challenge to help this idea scale. With a best-in-class nutrient and growing medium, Pina’s company has created organic compounds sourced from food waste for sterile, technology-driven hydroponic and soilless systems.

For the dynamic Pina, her vision for what became Re-Nuble started more than six years ago in the New York school system. “I also saw our outreach educational classes for this program were from 8 a.m. until 3 p.m.,” she recalled in an interview with The Spoon. “I noticed what the kids were bringing for class for lunch, and those options were very processed. With that diet, you see a direct impact on their level of attention. And I felt, from a systemic perspective, that will immediately impact the type of productivity and retention of the information we’re teaching. So overall, I always felt that people with better access to nutrition are spending more time being able to be fully immersed and retaining the information. And they are calling less out of work with fewer sick days.”

The genesis of Re-Nuble’s solution, Pina goes on to explain, came from her observation of how food waste was disposed of. “At that time, New York was spending $77 million to export its food waste to China, Pennsylvania, and Virginia. And that’s simply because we don’t have the composting infrastructure to handle it,” Pina said.” I wondered how we could make food waste a consistent alternative for conventional synthetic fertilizers by doing it for soils or hydroponic systems. So, we focused on using food waste as a viable alternative for chemical fertilizers in indoor grow environments.”

Specific to its product lines, Re-Nuble’s Head of Business Development & Strategy, Riyana Razalee, said in a company press release, “CEA is a large part of the future of farming, and so, we have to prioritize its role in decarbonization. Solutions need to address the gamut of the food supply chain, decarbonizing as many parts of it as possible. This vital issue is what our team is focused on”. The company states that for every acre of an indoor farm that uses Re-Nuble’s organic hydroponic nutrient, Away We Grow, the company can remove up to 5 metric tons of carbon emissions annually. That’s approximately one home’s energy use for a year.

In addition, its grow medium, ReNu Terra, supports the anti-peat movement. Companies, activists, and governments are demanding the reduction of drained peatlands. When farmed for agriculture needs, peat changes from a carbon sink to a greenhouse gas emitter, releasing approximately 1.9 gigatonnes of CO2e annually. This amounts to 0.4 billion gasoline-powered passenger vehicles driven for a year.

Pina said Re-Nuble has three customer segments now. First is the consumer market. Away We Grow could be part of a kit offered for an indoor growing system. “Consumers are eager to find more environmentally and people and animal-friendly solutions,” Re-Nuble’s CEO noted. The second segment is commercial farms such as Gotham Greens. The third, she said, is “disruptive farms.” For the last group, she stated, “There are severe supply shortages globally, and so there’s a lot of urgencies to find something that could be more sustainable, but even more importantly, something that they can afford.”

Oishii is Bringing its Specialty Indoor Strawberries to Los Angeles

The Omakase Berry is a varietal of strawberry grown in Japan known for its creamy texture, level of sweetness, and aromatic qualities. Courtesy of Oishii, a controlled environment agriculture (CEA) company that grows strawberries, Omakase Berries are coming to Los Angeles.

Oishii currently has two indoor farm locations on the East Coast in New York and New Jersey, and the new Los Angeles facility will be the first on the West Coast. According to the press release sent to The Spoon, Oishii is the “only vertical farming company to have perfected the strawberry at commercial scale”. Its indoor farms use zero pesticides, and its strawberries are a carbon-neutral crop.

When we last wrote about Oishii in April 2021, an eight-pack of the Omakase Berries cost $50. Unfortunately, heading west hasn’t resulted in lower prices, despite the company’s stated plans that it had plans to start growing an “everyday berry” that would be offered at a more affordable price. If you want to order the berries in Los Angeles, they are still set at the same expensive price.

With its focus on strawberries and other fruits and vegetables, Oishii stands apart from other indoor farm companies which mainly grow leafy greens and herbs. In October 2020, Driscoll and indoor farm company, Plenty, announced their partnership to start growing strawberries indoors. Hopefully, once Plenty makes it berries commercially available and Oishii develops an “every day” strawberry, consumers will have access to a more affordable indoor-grown strawberry.

The Omakase Berries are available for pre-order on Oishii’s website. The berries are available at a restaurant called Destroyer in Los Angeles.

InFarm Plots a Major Retail Expansion Across Canada

InFarm is partnering with Sobeys, one of the largest food retailers in Canada, to sell its vertically grown greens in grocery stores across the country. The Berlin, Germany-based indoor agriculture company plans to be in an additional four of 10 Canadian provinces by 2023. The deal will place InFarm in over 1,000 retail locations across Canada.

InFarm’s original entry into Canada happened in March 2020, when the company brought its small, pod-like modular farms to Sobeys stores, Thrifty Foods, and Safeway Canada, all subsidiaries of the Empire Company. These smaller farms can be placed directly in the produce section of a grocery store or nearby, making it possible for retailers to harvest greens onsite and sell them directly to consumers faster.  

For InFarm, this most recently announced expansion also means constructing more of its InFarm Growing Centers, which the company says are “growth, production and distribution hubs” that also hold high-capacity vertical farms. The company first announced these centers at the beginning of 2021, saying it had 15 of them either planned or under construction across major urban centers.

Modularity is the underlying principle behind both the pod farms in produce sections and the larger Growing Centers. The size of these farms can change depending on where they are located. As InFarm CEO Erez Galonska told The Spoon earlier this month, this modularity allows the company to respond to demand faster in any given area since it takes less time to launch a smaller farm compared to some of the industrial-sized operations out there. “If you think of larger-scale farms, they require a lot of upfront investment and can take some time to set up,” he said. “We took a modular approach to help address this, reducing the amount of cash needed to start operations and speeding up the process.”

In today’s announcement, InFarm said that its new deal with Sobeys comes in response to demand, and that it will increase production volume in Canada by sevenfold. New Growing Centers are planned for Calgary, Halifax, and Winnipeg. A site in Hamilton, Ontario will eventually host InFarm’s largest Growing Center in North America.  

Over the next five years, InFarm plans to expand its selection of produce to include tomatoes, strawberries, peppers, mushrooms, salads and potted plants. The company plans to have 100 growing centers in operation by 2025.

AeroFarms Talks R&D in the UAE for Vertical Farming

One place that gets a lot of attention these days when it comes to food tech initiatives is the United Arab Emirates. Like Singapore, the country is aggressively pursuing food and ag tech initiatives as a way to improve food security and quality within its own borders and in doing so become a more self-sufficient food producer.

The UAE got another big agrifood boost recently when New Jersey-based vertical farming company AeroFarms announced that its UAE-based subsidiary AeroFarms AgX LTD had started construction on an R&D facility in Abu Dhabi. The center will focus on new developments for indoor ag and controlled environment farming, and is expected to be operational in the first quarter of 2022.

“The region aligns very well with our value proposition,” Aerofarms cofounder and CEO David Rosenberg explained to The Spoon recently. “The UAE imports 90 percent of their crops, so there’s a food security issue. They also have relatively cheap energy.” He added that a facility for R&D in the country gives Aerofarms a “strong regional presence” from which it can expand to other areas in the Middle East and beyond. 

There’s certainly enough opportunity for indoor agriculture in this part of the world. Because of the desert climate, the UAE and other countries in the Middle East deal with a lack of arable land as well as water scarcity. Vertical farming operations like those of AeroFarms or another player, Vertical Field, claim to use significantly less water than traditional outdoor agriculture. And because of the vertical nature of the grow systems (plant trays are literally stacked inside a giant warehouse-like setting), companies can pack more plants into less space than would be possible on a horizontal field.

According to Rosenberg, the R&D center isn’t really to figure out how to grow food in the desert (“We could grow anywhere in the world”) so much as it is about growing plants specific to Middle Eastern eating habits in general. He cites mint and parsley, two popular foods in the region, as examples. Having an R&D center that focused on optimizing the grow cycle for these plants could increase quality, yield, and nutritional profile. 

The other goal of the forthcoming new center will be to apply the learnings discovered there to other parts of the region in the future. That includes research in areas like plant science, vertical farming and automation, accelerating innovation cycles and commercializing products.

Rosenberg says that versus a greenhouse, his company’s vertical farms can grow plants faster, producing around 26 harvests per year instead of 12 to 16. Right now, Aerofarms is best known for leafy greens, but the company has its sights set on other crops, too. In April of this year it announced a deal with Chile-based berry producer and distributor Hortifrut to research and develop blueberry and caneberry production. 

“Today we’re most known for leafy greens, but behind the scenes, we’re working with some of the biggest ag tech companies in the world to improve their genetics,” says Rosenberg. He adds that AeroFarms has grown 70 different varieties of berries, and that of the 550 different plants the company has grown, “probably 350 of them are in the leafy greens category.” He declined to elaborate on other crops, but suggested that information might surface soon to the public.

Last year, the Abu Dhabi Investment Office (ADIO) invested $150 million in a few ag tech companies, AeroFarms being one of them. The forthcoming R&D facility will be one tangible result of that investment. 

AeroFarms announced in March its intention to go public via SPAC with Spring Valley Acquisition Corp. 

Farm.One Launches a New Vertical Farming Facility in Brooklyn

NYC-based indoor ag company Farm.One cut the ribbon on its new urban vertical farm recently, this one located in Brooklyn, New York. According to the Brooklyn Reader, the 10,000-square-foot facility and will start planting seeds in the coming weeks. The Brooklyn farm is the company’s second large-scale farm, following its existing one in Manhattan’s Tribeca neighborhood.

Farm.One started out supplying its vertically grown greens to New York City’s high-end restaurant scene. The original goal was to grow rare, unusual plants restaurant chefs could then use in their dishes, a plan that worked until the COVID-19 pandemic started shutting down restaurants last year. 

In response, Farm.One took the same direct-to-consumer route many companies shifted to in 2020. NYC-based consumers can now sign up for a Farm.One subscription and receive greens and a few other local goods delivered to their doorsteps. The company has also teamed up with Brooklyn-based indoor farming company Smallhold to sell “local luxury mushrooms.” An additional collaborations with Rawsome Treats provides smoothies and plant-based bottled milks. Farm.One uses bikes for all deliveries and packages all items in reusable containers the company retrieves once they are empty. The shift to this model proved so popular that there is currently a waitlist to even get products. 

Hence the new farm space in Brooklyn’s Prospect Heights neighborhood, which opened at the end of last week. The space will grow various microgreens as well as herbs and some flowers. All crops are grown using the hydroponic method and artificial lighting, with plants harvested “hours before delivery,” according to the company. 

The Brooklyn farm will also include an event space where attendees can sample plants on “tasting tours” and attend lectures on food and agriculture. In future there may also be a daytime cafe as well as a cocktail menu.

Farm.One also licenses its technology out and currently has locations at the EATALY NYC Flatiron location and a Whole Foods in Manhattan. 

All of these offerings would classify as premium, targeting higher-end consumers. It remains to be seen if Farm.One’s demographic reach will widen as it adds more farms and is able to serve more parts of NYC and beyond. 

Survey: Indoor Ag to Expand, Add More Tech in 2021

Growers expect to add more technology to various forms of indoor farming for the rest of this year and into the next, according to indoor farm analytics company Artemis’ 2020 State of Indoor Farming report released yesterday.

The report, done in partnership with Startle, is based on a survey of 205 enterprise horticulture facilities, including those with high- and mid-tech greenhouses, indoor vertical farms, and container farms. Respondents answered a number of questions related to crop yields, labor, suppliers, and input. Underlying all of these things is the continued march of technology into the indoor farming space.

A commonly known point the report notes is that indoor ag typically requires more technology than traditional agriculture. For example, while glass greenhouses still use natural sunlight, the addition of LEDs can speed up the grow process for plants or provide more light in parts of the world where sunlight isn’t abundant. Meanwhile, more indoor ag companies these days are turning to tech that can help workers manage operations — an especially important point as farms get bigger and bigger.

To that end, survey respondents’ number one reason for implementing tech is “managing operations more efficiently” (39 percent of respondents). Lowering the cost of production (20 percent) and increasing yield (19 percent) were next. Getting better-quality crops, interacting with customers more effectively, and meeting food safety and compliance standards were also on the list.

In the next year, 19 percent of respondents said they plan to implement data and analytics, while 18 percent will add climate control systems and 17 percent will add labor tracking and cultivation management software. Following those items, growers plan to add more LEDs as well as post-harvest automation equipment and organic nutrients. Remote monitoring and automated scales for weight measurements were also mentioned.

The majority of growers, 73 percent, also plan to expand significantly over the next five years, with a combined expansion of 544 acres total. Mid-tech greenhouse companies — glass or polycarbonate greenhouses that use some tech but not “to the full extent possible” — will expand the most, at 206 acres, followed by container farms at 156 acres and indoor vertical farms at 84 acres.

Echoing this, numerous companies in the space have announced expansion plans in the last few months, from vertical farm company Kalera’s ongoing trek west across the U.S. to Square Roots’ expansion of its container farm network and a second 60-acre greenhouse from AppHarvest. In terms of acreage, greenhouses are likely to grow the most, since they typically don’t use vertical farming technology and often grow crops that require more space than the compact leafy greens that are so popular.  

And speaking of leafy greens, those along with herbs still account for almost half of all crops grown via indoor ag right now (26 percent and 20 percent, respectively). Microgreens (16 percent) are next, followed by tomatoes (10 percent). Other crops, such as strawberries, may become more prevalent as companies leverage new technologies and methods for growing indoors.

Meet HECTAR, an Open-Source Project for At-Home Vertical Farming

When it comes to at-home vertical farming, who will be first to grow a watermelon?

That’s a question posed by HECTAR Hydroponics, a project that wants to open-source the at-home vertical farm concept. Rather than mass-producing a whole farm and selling it to consumers, the project’s creators have instead made a manual and documentation available for free download, so that any DIY enthusiast can build their very own HECTAR.

Felix Wieberneit of the Royal College of Art and the Imperial College of London conceptualized HECTAR, which eventually became part of Imperial College’s Venture Catalyst accelerator program, a competition for entrepreneurs sponsored by Huawei. The HECTAR vertical farm is the size of a regular bookshelf and can grow up to 128 plants, according to the project’s website. So far, users have grown kale, spinach, and other leafy greens, as well as green beans.

According to the publication Springwise, HECTAR was partly inspired by what Wieberneit saw as a need for more affordability and versatility with at-home vertical farming: “Wieberneit wants to change the market for hydroponic systems from ‘overpriced smart planters and costly seed subscriptions’, to systems that people design to meet their own needs, which use local materials.” 

Thus far, most large-scale vertical farming companies use either proprietary tech developed in-house or a proprietary mix of off-the-shelf technologies. Information on what works and what doesn’t in terms of the technology is few and far between right now, a situation that also applies to at-home versions of vertical farms.

Hence, Hectar. The plans, released under the Creative Commons Attribution 4.0 International, include a step-by-step guide, an instructional video, and a list of materials, all of which can be purchased from the average hardware store.

A few questions come to mind when thinking of HECTAR in the larger context of at-home vertical farming. For instance, how much does it cost? Do all the materials listed add up to something cheaper than, say, a complete farm from Rise Gardens ($549+) or Gardyn? ($899 for a starter kit). What will the quality of the produce be like compared to those or even compared to what you could buy at the store? 

Those questions will no doubt be answered in time on the project’s community forum, where growers can share tips and advice as well as any improvements and/or changes made to the design. No one’s reported any watermelons yet, but open-sourcing the vertical farming concept might just be the way to get there.

Plenty Expands to More Stores in Northern California, Launches Text-a-Farmer Feature

Vertical farming company Plenty today announced an expansion to 17 more Safeway stores across Northern California, as well as a new tech feature that lets shoppers text Plenty’s farmers directly.

According to a press release sent to The Spoon, the Northern California expansion is part of the multi-year deal between Plenty and Safeway parent company Albertsons. Through that deal, leafy greens grown in Plenty’s controlled-environment vertical farming facility in the San Francisco Bay Area get shipped to Albertsons stores up and down California. The goal is to eventually get plenty’s produce into more than 430 Albertsons stores, including those under the Safeway and Vons brands.

Simultaneous to this expansion is the launch of what Plenty calls its Text-a-Farmer feature. The tool functions much like its name suggests. A sign in the grocery store’s produce section will display a number users can text questions to. Those questions can be about anything related to Plenty’s produce, from “How should I store my greens?” to “Is your packaging recyclable?” Plenty farmers answer the questions in real time via text with the customer.

The Text-a-Farmer feature will be available at stores selling Plenty’s produce. The idea is to give shoppers more information about their food while they are still in the store.

Commercial-scale vertical farming as a whole, meanwhile, continues to expand, raking in the investment dollars in the process. Bowery, based on the East Coast U.S., recently announced its most “technologically advanced” farm to date, while Orlando, Florida-based Kalera is building out facilities across the U.S., including Colorado and Texas. On the investment front, GoodLeaf just raised $65 million to expand across Canada, Stockholm, Sweden-based Urban Oasis raised $1.2 million, and Plenty itself nabbed $140 million. The latter happened this past October.

Around the time of that investment, Plenty also announced a partnership with Driscoll’s to grow strawberries via vertical farming. Plenty also operates a farm in Compton, California, to service southern parts of the state. 

iUNU Raises $7M Series A for Computer Vision Approach to Indoor Growing

IUNU, which builds computer vision and machine learning systems to add more precision to indoor farming, announced today that it has raised a $7 million Series A round of funding led by S2G Ventures and Ceres Partners.

IUNU (pronounced “yoo-noo”) makes Luna, a robotic system of cameras both fixed and mounted on rails that go on the ceilings of commercial greenhouses. Using these cameras, environmental sensors, computer vision and machine learning, iUNU can measure everything about plants being grown down to the growth rate of each individual plant. If Luna detects changes in the health of plants, it can alert growers so they can take action to improve product quality and yields.

The indoor agriculture space is certainly hot right now, and has seen downright frothy amounts of investment. BrightFarms raised a $100M Series E round in October, Plenty raised a $100M Series D round that same month, and Urban Oasis raised $1.2 million just last month. And just today, Gotham Greens raised $87 million for its high-tech greenhouses.

Beyond straight up fundraising, the indoor farming is also in the midst of a growth boom. AppHarvest is building out the world’s largest greenhouse in Kentucky, and YesHealth Group and Nordic Harvest are building “Europe’s largest” vertical farm.

It’s not hard to understand why there is so much going on in indoor ag right now. The population of our planet is expected to hit 11.2 billion by the end of the century, up from 7.7 billion in 2019. All of those people need to be fed, and more importantly, fed in a way that doesn’t exacerbate environmental problems. With its precision technology, and the ability to move food production closer to consumers, indoor farms hold the promise of creating a more equitable food system.

Unlike the other players mentioned above, iUNU is not a full-stack solution. It’s not in the business of growing its own greens. The Luna system can be used to help make existing greenhouses more productive and could presumably be built into these new indoor farms coming online.
