With the planet in crisis, some of the most impactful technological advancements today are focused on lessening humanity’s impact on the planet. The Sustainability winners of Fast Company’s inaugural Next Big Things in Tech awards are creating batteries that can power a renewable future. They’re reducing food waste (or turning it into fertilizer), making our appliances more efficient, and recycling everything from wood scraps and shingles to lithium-ion batteries.
See a full list of the Next Big Things in Tech across all categories here.
For producing fertilizer from food waste
Traditional fertilizer comes from gas. Anuvia provides a sustainable alternative by turning food and farm waste into nutrients that can improve soil health and help plants grow. The treatment can boost agricultural yield up to five times, while reducing the emissions from traditional fertilizer production by nearly a third.
For helping cities understand—and monetize—vehicle traffic
Using video cameras mounted to light poles, Automotus automates the process of charging drivers for parking and enforcing no-parking zones. It also provides cities with valuable (and anonymized) insight about how their streets are being used—and gives companies doing deliveries real-time information about where to park, reducing congestion.
For designing an operating system for crops
Inside Bowery’s vertical indoor farms, cameras and sensors capture 100,000 images every day. The resulting data helps the company track how quickly crops are growing, accurately predict harvests, and automatically adjust conditions such as lighting and humidity if even a single leaf is wilted or the wrong color.
For saving trees through 3D printing
Working with wood results in lots of waste in the form of sawdust and odd-shaped scraps. Desktop Metal’s Forust grinds up these leftovers and 3D prints them into new pieces that can be used in home goods, accent work, and architectural detailing. Its software can now digitally reproduce nearly any wood grain and texture.
For fighting food waste with CO2
By pasteurizing food with high-pressure carbon dioxide, Farther Farms is able to transform produce, dairy, and meat so that they can last months without refrigeration. The technology could be especially useful in the developing world, where the limited cold chain leads to more food waste.
For creating the battery of tomorrow
Using iron and air instead of lithium, Form developed a prototype for an ultra-affordable battery that’s designed for long-term storage of renewable energy; the battery could be available as early as 2025. The technology’s use of iron is designed to bring down the cost of materials to less than $20 per kilowatt-hour—far less than any currently available battery on the market.
For cleaning up our roofs
Asphalt shingles are on more than 75% of U.S. roofs—and end up in landfills when roofs are redone. Shingle maker GAF—part of Standard Industries—has pioneered a process that reclaims 90% of the materials from old roofing. The new technology allows shingles to contain up to 15% recycled material, adding some welcome circularity to the roofing economy.
For creating a practical—and scalable—electric-vehicle battery
Instead of designing the battery systems for each new electric car from scratch, GM created the Ultium platform to allow for a single battery architecture to be used in all its vehicles. Debuting in the 2022 Hummer EV, the technology will reduce costs and smooth the carmaker’s transition to an all-electric fleet.
For keeping batteries out of landfills
The lithium-ion batteries that power our phones and computers are made from precious, hard-to-mine metals, but when we’re done with the devices their batteries usually end up in the landfill. This startup’s low-cost, low-emissions recycling method is able to save up to 95% of the components from these batteries for future use.
For electrifying short flights
This electric propulsion system for planes has powered real zero-emission flights, taking aircraft as high as 8,000 feet. The company expects FAA approval soon. When that comes, flights under 500 miles could be completed with zero emissions—and no noise.
For growing a sustainable leather alternative
The company’s fungus-based Fine Mycelium material is made to replace leather in the fashion industry. More sustainable than cow skin, it can be grown to customer specifications (including size and appearance) in six weeks, then tanned for use in jackets, shoes, and bags.
For turning school buses into batteries
When you charge an electric car, energy flows from the grid into your auto’s battery. Nuvve’s technology reverses that process, allowing the energy in an unused vehicle’s battery to flow back into the grid, adding capacity to the system. It’s being piloted in school buses, which only get used for a few hours each day.
For getting smart about water consumption
Wint’s Water Intelligence technology detects anomalies in water flows, allowing food and beverage plants to operate more efficiently and cut water consumption. A pilot program with PepsiCo cut water consumption at a Belgian snack facility by 10%; now PepsiCo is rolling out Wint’s tech to five European sites.
For using AI to reduce restaurant food waste
Food-waste startup Orbisk and data annotation company Sama built an AI tool that lets restaurants scan a plate of leftover food and detect what’s going in the trash. Chefs and restaurant managers can use this information to adjust their menus, shrinking food waste by as much as 70%.
For redesigning motors to run more cleanly
Electric motors—like the one running your refrigerator or air conditioner—account for more than 50% of global electricity consumption. Turntide’s smart motors reduce both energy use and the need for repairs, which could help drastically cut emissions from those devices.
For making cell-grown meat a reality
A pioneer in the field of “cellular agriculture,” Upside Foods (formerly Memphis Meats) is developing meat and seafood grown from animal cells without the need for high-emissions livestock and at a cost that can eventually compete with conventional meat. The company’s pilot production facility is set to begin operating by the end of the year.
For rethinking agriculture with massive indoor AI-powered farms
For using data to help the world understand the future of water
For sustainably recycling all plastic types at scale
For customizing LED lighting to help greenhouse farms prosper
For building underground caverns for long-term energy storage
For creating a healthy new protein source through advanced fermentation
