With nearly a third of the world's food going to waste, here are some small companies working to make food waste edible.

Every year 1.3 billion tons of food is wasted, costing over $1 trillion around the world. Even though food waste breaks down faster than other types of waste such as plastics, the decomposition produces a significant amount of carbon dioxide, which exacerbates climate change. There are ongoing efforts to confront this issue, such as the Biden-Harris Administration’s National Strategy for Reducing Food Loss and Waste and Recycling Organics announced on June 12, 2024. Many small companies and organizations are working to address this issue as well. Here are six businesses that have found innovative ways to transform food waste.

1. Back to the Roots’ Mushroom Growing Kits

Every year about six million tons of coffee grounds end up in landfills around the world. Back to the Roots is a company that sells mushroom growing kits that use recycled coffee grounds. Back to the Roots aims to make food growing accessible while keeping used coffee grounds out of the landfill.

After connecting with each other during college through a shared interest in growing mushrooms from recycled coffee grounds, Back to the Roots’ co-founders Alejandro Velez and Nikhil Arora began growing mushrooms in Velez’s fraternity. 

Back to the Roots has found many ways to give back to communities. Through their #GrowOneGiveOne campaign, customers can post a picture with their growing kits and Back to the Roots will send a growing kit and curriculum to an elementary school classroom. People can also access free kids gardening curriculums and gardening resources, including a garden glossary, grow calendar and grow guide. You can explore Back to the Roots’ mushroom growing kits and resources here.

2. Cascara Foods’ Supplements

Cascara Foods is a Chilean company that transforms food waste into health supplements. Nutrients from fruit pulp and peels are used in supplements for digestion, joints and more. Cascara was started in 2017 in order to combat climate change, and the company strives to upcycle as much fruit waste as possible. 

Currently, recycled apple, blueberry and strawberry fibers can be found in Cascara's supplements. The apple fiber is leftover from local producers in the apple juice industry and contains more than 90% of the total fiber of the whole fruit. Blueberry fiber salvaged from the juicing industry and strawberry fiber sourced from the puree industry are both sources of antioxidants and can also serve as natural food colorings.

3. EatKinda’s Cauliflower Ice Cream

EatKinda is a New Zealand-based company that sells ice cream made from cosmetically imperfect cauliflower. As with many other countries, New Zealand’s supermarket standards often reject produce based on aesthetic issues such as size or color, creating unnecessary food waste. EatKinda collects cauliflower from local farmers and supermarkets that would otherwise end up in the landfill and transforms it into a delectable treat.

EatKinda’s co-founder Jenni Matheson stumbled across her cauliflower ice cream recipe after a failed attempt at making a vegan cheesecake. Then, when Matheson met food technologist Mrinali Kumar, they got to work and EatKinda was born.

EatKinda currently offers three vegan flavors, including Strawberry Swirl, Double Chocolate and Mint Choc Bikkie, and its products can be found in 90 stores throughout New Zealand. The cauliflower ice cream has recently gone viral on TikTok, and EatKinda is in the process of seeking investors to expand into Australia and beyond. Here is where you can learn more about EatKinda.

4. Imperfect Food’s Grocery Delivery Service

Imperfect Foods is an American company that combines sustainability with convenience. By delivering retailer-rejected food products to customers’ doors in 100% recycled boxes, Imperfect Foods has saved over 160 million lbs of food waste from the landfills. All of these food items had been rejected for various reasons including aesthetic issues, surpluses or being near their best-buy dates.

Sustainability is kept in mind through every step of the grocery delivery process. By delivering all the groceries for each neighborhood in one trip and using 100% recycled boxes collected from previous orders, Imperfect reduces waste and carbon emissions. By signing up online, customers can limit food waste and get everything from farm-fresh produce to pantry staples delivered to their door. You can discover more about Imperfect Foods here.

5. Sweet Benin’s Cashew Apple Juice

The cashew industry is prominent in Benin, but every year ten million tons of cashew apples are left to rot in fields across Africa. Sweet Benin limits food waste and supports local communities by working with producers to transform these leftover cashew apples into juice. 

The cashew apple is the fruit attached to the cashew nut. Despite the many uses for cashew apples, many consider the fruit trash because of a misconception that it is poisonous. Sweet Benin started countering this misconception after partnering with the non-profit TechnoServe in 2017. Since then, the company has strived to support economic growth while prioritizing women in the hiring process. TechnoServe offers further information here.

6. Toast Brewing’s Beer

With about 44% of bread going to waste, Toast Brewing has set out to transform this surplus into beer. The over three million slices of bread saved by Toast Brewing since 2016 could be stacked nearly as high as five Mount Everests. So much bread can be saved because Toasted uses it to replace 25% of the malted barley it uses to brew beer.

Toast Brewing supports sustainability through charity as well. 100% of the profits go to environmental charities. The company has also partnered with the social enterprise Change Please and created a cafe taproom that helps fight houselessness and food waste.
