Every other Saturday, I volunteer at a nonprofit that is very dear to my heart. Emeryville Citizenship Assistance Program (ECAP) is a food bank that distributes food waste from large food branches like Trader’s Joe to those in need. 

I love volunteering at ECAP because it has more than one impact. It both feeds the community and prevents edible food from being wasted. Most of the food that we receive is only slightly imperfect: a dented can of beans, a spoiled orange in a bag with twenty good ones, or a delicious-looking cake that’s about to expire. Stores cannot sell these flawed foods. If it were not for ECAP, they’d probably end up in the trash.

This is a huge problem. Every year, 31% of the American food supply — worth $161 billion dollars — goes to waste. All the water, energy, and nutrients used to make this food were spent for nothing. This increases the pressure on water and land resources, and the waste ends up contributing to pollution and carbon dioxide emissions — exacerbating global warming.

But the problem can become an opportunity. Just as ECAP gives a new purpose to discarded food, some startups understand that it can be a good source of revenue. 

The startup Too Good To Go, valued at $1 billion, sells food stores don’t want at reduced prices to consumers. Stores make money, customers get food at discounted prices, and the startup takes its cut. Between 2015 and 2020, Too Good to Go saved 86,747 tons of carbon dioxide

Perfekto has the same ambition in Latin America. It is a grocery subscription company selling food that is unwanted due to cosmetic imperfections, short shelf lives, or labeling and inventory errors.

When food isn’t edible anymore, composting can redirect the nutrients toward the ground. Blue Earth Compost makes composting easy and accessible to buildings and businesses.

Reducing waste — or giving it a second life — is one of the best things we can do both for the planet and for food security across the world. It’s also a growing market, and startups are not wasting the opportunity. Will you?

At the height of COVID-19, most of the United States population wore single-use masks. What was a sanitary necessity also created a tremendous amount of waste. The world produced 52 billion single-use face masks in 2020, all becoming garbage after a day or so of use. Worse, an estimated 1.6 billion masks entered the ocean that same year. Canopy produces a sustainable alternative to single-use masks. Its award-winning product is form-fitting, safe, comfortable, and suitable for both frontline workers and consumers. 


Blue Earth Compost 

Composting is a great way to give a second life to inedible peels, seeds, or spoiled food. But it is easier to do when you have your own garden.

Blue Earth Compost is making composting accessible to homes, businesses, and municipalities. It provides waste collection services, guidance, and containers to help clients separate food waste from their trash stream.
