9 Startups Taking a Bite Out of Food Waste

We love our food here at Nanalyze. Globalization means that all of our favorite cuisines can be sandwiched onto one urban foodie block. It’s possible to buy tropical fruits like mangosteens in wintry Vancouver or navel oranges in an open-air food market in Thailand. All that food comes with a price, and we’re not just talking the markup in hipster whole food co-ops. Food waste is a trillion-dollar by-product. Or, more accurately, food waste costs the world about $1 trillion per year, according to the Food and Agriculture Organization of the United Nations. In the United States, food waste is estimated at between 30 to 40 percent of the food supply. That’s more than $200 billion ending up in the compost heap (though only about 25 percent of Americans actually compost).

You would think that with a trillion dollars on the table there would be a million startups clamoring for a piece of that molding pie. But investors only poured a miserly $93 million into food waste tech startups in 2015, according to AgFunder, which said the following year was no better. In the first half of 2016, food waste tech startups had only $29 million to pick over. At least by the end of the year, biotechnology startup Apeel Sciences took in $33 million, and as of September 2017 sat at No. 13 on our list of top 14 funded agtech startups. As you may recall, the Santa Barbara startup has developed a coating using natural plant extracts taken from recycled agricultural byproducts to extend the shelf life of produce after it’s been harvested.

As we started to dig through food waste tech—not as gross as it sounds—we found that the space is extremely diverse. There are companies turning banana peels into fertilizer and fuel (flux capacitor, anyone?) and countless apps that promise to keep homely, unwanted fruit out of the trash bin. Below, we highlight some of the interesting markets and opportunities that startups are creating out of food waste tech. As always, this list isn’t meant to be exhaustive.

The Fertile Crescent

Click for company websiteFounded in 2010, waste tech startup WISErg Corporation out of Washington State has raised $56.6 million to date, with a $19.2 million Series C last month boosting that total. The company produces fertilizer, mainly through food waste such as meats and produce sourced from grocery stores and restaurants. Its clients use the company’s Harvester, which grinds food waste into a slurry that retains more than 90 percent of the nutrients versus 40 percent from traditional composting. The machine even provides actionable data to WISErg customers, such as the types and amounts of waste being ingested to help guide future purchasing decisions. WISErg then collects the stabilized stew of food waste and processes it in a liquid fertilizer, which is certified for use on organic farms. In one study, when WISErganic was applied to sweet corn, total yield increased by 16 percent per acre over the control. The new funds will help the company build a second facility in California, where it will bring food waste for both liquification and processing, with hopes of pushing eventually into markets south of the border, according to AgFunder News.

It has raised about $13 million, including a $3 million round last August. A second company, called KDC Agribusiness, was founded specifically to commercialize the technology. Like WISErg, California Safe Soil converts supermarket waste into liquid fertilizer, as well as feed pellets for chickens and pigs. The company claims its trademarked Harvest-to-Harvest fertilizer can increase organic yields by 10 to 40 percent per acre with 25 percent less water.

Founded in 2014, Industrial/Organic (with the sort of name you would expect from a company out of Brooklyn) got about $1.3 million last year in Seed money to prove its food waste tech. Its fermentation process is reputedly six times faster than traditional anaerobic methods, churning out products like organic fertilizer, animal feed, and even surface cleaners. Its model is to locate small facilities throughout an urban area, without emitting greenhouse gases or food waste funk.

Hard Alcohol

Click for company websiteIf all this sounds familiar, then you might remember our feature on Harvest Power. In addition to creating high-powered fertilizers, however, Harvest Power is also attempting to turn waste food into fuel. In the course of our research, we came across Blume Distillation out of California, which was founded in 2009 and has raised about $3.2 million to date. Unlike Harvest Power, which produces biogas that can be converted into natural gas for electricity, Blue Distillation manufactures large-scale systems for converting food waste and other bio waste into alcohol. Blume uses two basic system models to provide production capacity in the range of 20,000 to 500,000 gallons of bio-ethanol per system per year.

Its products are used in everything from flex-fuel vehicles to fuel stoves in third-world countries to replace dirtier cooking technologies.

Weighing Your Options

Click for company websiteOf course, it would be great if we could avoid wasting all that food in the first place. London-based Winnow Solutions, founded in 2013, has taken in $11.5 million toward that goal, including a $7.4 million Series B last October. Its “smart scale” helps restaurants calculate how much food—in both quantity and cash—the kitchen wastes on a daily basis. Reports help management analyze food waste in near real-time and offer suggestions on how to do it better. One of its biggest clients is IKEA. In one store, the restaurant reduced food waste by 40 percent, saving about $120,000 in one year. That’s a lot of Swedish meatballs.

Update 10/16/2019: Winnow has raised $12 million in Series B funding to further improve its technology and “double down” on product development. This brings the company’s total funding to $31.6 million to date.

Click for company websiteWinnow isn’t the food waste tech startup competing in this space. Others include LeanPath out of Oregon. Founded in 2004, the company offers several products including its all-in-one LeanPath Tracker 2.2, which includes a built-in scale, camera, and touchscreen user interface. Before throwing away any food waste, a worker places the food on the scale, the camera snaps a photo, and the user inputs a few pieces of info, which generates an online report. LeanPath says its system has been installed in more than 1,000 kitchens across more than 20 countries. In one case, at Boston College, the kitchen reduced food waste by 60 percent.

Meanwhile, a California company called MintScraps, founded in 2013, offers a cloud-based analytics platform for tracking food waste. New York City offered the app to restaurants, supermarkets, cafes, and other businesses to track and visualize their waste streams as part of the city’s efforts to divert food waste from landfills. The program saved 2,500 tons in its first six months. The app also provides a marketplace where businesses can post leftover food for pickup and non-profits and food banks can search for food to pick up.

An App for That

Click for company websiteTurns out there are a ton of such marketplaces and apps that find a home for unwanted food.  For example, Australian-based Yume, founded in 2014, has raised about $2 million for its online platform where vendors can offload surplus food before it spoils at deeply discounted prices:

Mega food company Unilever is among the list of suppliers. Yume also helps donate unsold surpluses to charity. Food+Tech lists several more variations of these types of companies here.

Keeping It Fresh

Click for company websiteWhile leftover fast-food burgers may seem as immortal as a Greek god, most food will eventually rot. Another way to stave off food waste is to find better ways to keep it fresh. Founded in 2006, San Francisco-based BluWrap has raised $12.6 million for fuel cell technology that helps extend shelf life of protein while in transit aboard container ships.

BluWrap uses fuel cells to manage oxygen levels in refrigerated containers, extending the shelf life of fresh proteins well beyond 40 days. Sensors continually monitor oxygen and temperature levels throughout the journey. So that means a shipment of pork from Europe to Australia doesn’t need to be frozen or vacuum-sealed to survive the ride overseas.


Unlike other sectors of tech, food waste is a problem in search of a solution—and there are plenty on offer. Of course, we’re not seeing the sort of money that’s being dumped into other areas, but as we noted in our feature on Sadako Technologies, there’s money to be made in garbage. The strongest contenders for an IPO or M&A in the future are probably those startups turning food waste into fertilizer or fuel, which are attractive technologies for companies like Monsanto, Cargill or Waste Management. Otherwise, while there are some interesting solutions emerging, most seem quite niche at this point.
