Renewal Mill: Making a profit while committing to sustainability

Renewal Mill Renewal Mill: Making a profit while committing to sustainability
Incorporating upcycled products and ingredients can make a difference for many brands as they seek to make sustainability part of their production processes.

Consumer expectations are growing. Many want brands to make commitments toward sustainability, carbon reductions and other targets related to food waste and packaging. That mindset influences purchasing behavior.

According to the Natural Resources Defense Council, up to 40% of food produced in the U.S. is never eaten. That has a major environmental impact on greenhouse gas emissions throughout the cycle of growing, processing, transporting and disposing of wasted food.

"People know food waste is a problem and they want to know what they can do to help," says Caroline Cotto, co-founder and chief operating officer of Renewal Mill, a company that upcycles byproducts from food manufacturing into ingredients and natural products.

Brands need to move towards making sure 100% of the food produced is being returned to the food system instead of "arbitrarily labeled as waste products," Cotto says.

Creating a circular food economy in which upcycled ingredients are diverted from a landfill and become profitable revenue streams takes practice and ingenuity.

Educating consumers, starting with food waste

Caroline Cotto, co-founder, chief operating officer, Renewal MillWhen Cotto and Claire Schlemme co-founded Renewal Mill in 2016, they needed to educate retailers and consumers about upcycling. Their long-term goal: reducing supply chain inefficiencies by reducing food waste.

"We had to start the conversation, with, 'Do you know food waste is a problem, let me tell you about that,' and eventually got to talking about upcycling," Cotto says. "Now, that conversation has really evolved."

The Upcycled Food Association—Cotto sits on the board of directors—has helped standardize the industry. "Before that, the language and messaging around upcycling was the Wild West because everyone was talking about it in a different way," Cotto says about UFA, which now has more than 200 members. "The new certification can help consumers immediately recognize upcycled food, which has been a game changer."

Cotto and Schlemme entered the business of upcycling after Schlemme started Boston's first organic juice company, Mother Juice, and hated seeing all the food waste from the pulp byproduct. "And then we had a fortuitous conversation with the owner of Hodo Foods, one of the largest tofu companies in the U.S. which was having similar pulp waste problem, but on a much larger scale," Cotto says.

The two brands formed a partnership and, after a lot of research and development, realized the pulp leftover from soy milk production was a "really valuable ingredient" called okara. Traditionally, the ingredient has been used for animal feed.

Renewal Mill began dehydrating and milling the soy pulp—sourced from Hodo Foods—into gluten-free organic okara flour, and started investigating uses for other pulp byproducts.

"We realized if it was happening in one plant-based milk, it was probably happening in other plant-based milk productions," Cotto says.

Renewal Mill, which won a 2022 "Best New Planet-Forward Product" NEXTY Award for its upcycled Matcha Chip Cookie Mix, expanded its offerings into upcycled ingredients and products, including oat flour made from the pulp leftover from oat milk processing, individually packaged goods such as vegan okara chocolate chip cookies and baking mixes like its vegan, gluten-free sugar cookie mix.

To grow, find a product developer

To expand its lineup, Renewal Mill knew it needed to find someone who could make unusual ingredients feel familiar to customers.

An introduction by Sam Butarbutar, the co-founder and culinary director of Third Culture Bakery, helped Renewal Mill partner with Alice Medrich, a five-time James Beard award-winning cookbook author and pastry chef who specializes in gluten-free and alternative flours, on product development.

At the time, okara was pretty unfamiliar to most people in the U.S. and many consumters didn't know how to use it, Cotto says.

"We were struggling with how to make it approachable," Cotto says.

Medrich became a product developer for Renewal Mill, creating recipes and formulating offerings, including the brand's Dark Chocolate Brownie Mix, Snickerdoodle Cookie Mix and a variety of recipes, including an extra virgin olive oil cake recipe, as the company expanded into the baking space.

Medrich found different ways to use upcycled ingredients to make products look recognizable. The brand began sharing simple-to-use food swaps, such using a cup of oat milk flour in a chocolate chip cookie recipe, to show customers easy ways to substitute and bake with upcycled ingredients

"Sustainability might be enough to get customers in the door, but you have to show how an ingredient performs on functionality, on cost and on a taste perspective," Cotto says. "Alice was instrumental in that process."

Research FDA, USDA-recognized ingredients

The upcycling movement is growing quickly. According to a spokeswoman, the Upcycled Food Association has more than 200 members across 20 countries, up from 100 members in 2020. Last year, Whole Foods Market named upcycled foods a "Top 10 Food Trend."

Plenty of other natural product companies now upcycle, including Take Two, which makes plant-based barleymilk, and Abokichi, which makes miso soup and condiments containing sake lees (also called sake kasu) the paste-like byproduct from making sake.

Before a company decides to use an upcycled ingredient, Cotto recommends doing some research. Find out if it's an FDA and USDA recognized ingredient that's been peer-reviewed for its health benefits.

If it's not, the journey to getting an ingredient to be recognized by the USDA and FDA can be quite challenging, Cotto says.

Share the story with retailers

Retailers can help natural product brands by educating consumers about upcycled products and ingredients. Share details about the Upcycled Food Associations' Upcycled Certification Program, the world's first third-party certification program for upcycled products and ingredients, Cotto says.

"Retailers play such an important role in driving the conversation around different trends," Cotto says. "Especially with upcycling."

Tell a story and show the "circular economy" by grouping and selling similar products like okara flour, which comes from the tofu byproduct that is sold in other products like Pulp Pantry chips, says Cotto. In September, MOM's Organic Market became the first grocery store in the U.S., to create an in-store set solely dedicated to upcycled products.

Renewal Mill has diverted 350,000 pounds of food waste from landfills since 2016, according to Cotto.

"It resonates with consumers when you say, 'We had a singular soybean and it created all of these products and nothing went to waste,'" Cotto says. "Or say, 'This is upcycling and you're helping fight food waste, which is a key drive of greenhouse gas emission.'"
