Upcycling Food Waste into Delicious Superfoods — Claire Schlemme, CEO of Renewal Mill
Led by Claire Schlemme Renewal Mill reduces food waste by upcycling the byproduct of plant-based milk to create high-quality Okara flour and baking mixes. The company's Okara flour is used in products made by other plant-based food makers while its baking mixes are sold directly through its website.
Claire summarized Renewal Mill's business saying, "Renewal Mill is an upcycle food company. We upcycle byproducts from food manufacturing into superfood ingredients and premium pantry staples. We are currently working with the pulp residue from plant-based milk. This pulp material is nutritious and has a lot of fiber and protein. This leftover pulp is often wasted and certainly not processed and upcycled at scale as we are attempting to do. For soy milk residue, we dry out the pulp and produce it as “okara,” which has an East Asian heritage. For oat milk, we perform a similar process and brand the material as upcycled oat protein flour. Our goal is to ultimately move beyond the plant-based milk space and continue to capture otherwise wasted sources of fiber and protein. There are numerous opportunities to do this in the tomato and potato spaces in particular."
Claire spoke to the importance of mission alignment in seeking outside capital saying, "For the first two years, the company was funded through grants from both Yale and the Closed Loop Foundation. We recently received funding from Kroger as part of their Zero Hunger Initiative. We have also employed more traditional forms of capital raises with convertible and SAFE notes. Our funding sources have been mostly in the impact space. When we first incorporated the company, we did so as a public-benefit corporation, which I believe has been powerful in filtering our potential investor list to the most mission-aligned subset. We have received funding from traditional waste-to-value investors as well as an investor that focuses on plant-based food systems."

Sensor-Based Innovation: Save Money and Reduce Food Waste in the $1 Trillion Cold Chain— Manik Suri, CEO of Therma
Led by CEO Manik Suri, Therma is deploying next-generation IoT devices to reduce product waste and decrease energy waste throughout the global cold chain.
To learn more about Therma visit their website.
Manik noted the company's product offering saying, "Therma stands for Temperature Humidity Equipment Remote Monitoring Application. Our technology is an Internet of Things device that reduces the waste of energy, product, and refrigerants across the refrigeration supply chain."
Manik highlighted the scale of the refrigeration industry saying, "The refrigeration industry is interesting but probably not something that the layman has given much thought to, and frankly, I hadn’t given it much thought either until a few years ago. The industry has been around for about 150 years and hasn’t seen as much innovation as you might think. The “refrigeration cold chain” is used to describe all of the refrigeration assets that help keep perishable products cold across the life cycle. There are a couple hundred million units of refrigeration assets in the commercial and industrial sectors alone. There is more than $1 trillion worth of inventory moved through these refrigeration assets each year from fruits and vegetables to pharmaceuticals and blood plasma. The scale of the cold chain is growing at approximately 11% a year with growth fueled by the developing world. There are estimates that China’s current cold chain is only 20% of its full potential while the estimate is closer to 10% in Africa."

SaaS Solution for Corporate Climate Intelligence and Risk Management — Laura Zizzo and Jeremy Greven, Manifest Climate
Led by co-founders Jeremy Greven and Laura Zizzo, Manifest Climate is a building a climate intelligence platform to help companies better understand, manage, and communicate climate risk. To learn more about the TCFD standards that Manifest Climate looks to broadly implement visit their website.
Below are two excerpts from the podcast.
Laura highlighted the company's mission and product offerings saying, "Manifest Climate is a climate intelligence platform for business. We help customers translate climate so that they can better understand it, manage it, and disclose it to investors. We help clients communicate climate risk to investors and internally within their companies so they can make decisions that enhance business resiliency. We want to take climate out of the sustainability silo and put it into the organizational framework."
Jeremy spoke to the company's evolution saying, "The company and its product offering have evolved with market demands. The company was born out of Mantle 314, a management consultancy company working with big financial institutions globally. It eventually became clear that boardrooms across the world were demonstrating a common need for better information concerning the management of climate. However, the combination of commonality and impact at scale makes this problem uniquely suited for a software solution. Ultimately we are bringing a “SaaS plus” model to the market where we can leverage technology to build upon the experiences and insights of subject matter experts on our team that have over five years of experience working with corporate clients in the climate space. In addition to the technology layer, we can offer a higher-touch service with custom reporting broken down by business lines as well as workshops where management teams can engage with Q&A and get one-on-one time with subject matter experts on our team."

Below are two excerpts from the podcast.

"I believe the majority of the unelectrified homes in the United States are on Navajo Nation property. There are somewhere between 15,000-18,000 homes on Navajo Nation property that lack access to electricity or reliable electricity. I think many of us do not realize that some of these homes that you drive by each day do not have running water although large transmission lines run overhead."

Nature-Based Carbon Removal with the World's Fastest Growing Tree — Doug Willmore, CEO of World Tree
Led by CEO Doug Willmore, World Tree acts as a platform to facilitate the planting of Empress Splendor trees to sequester carbon while generating returns for both farmers and investors through both carbon offset and lumber sales.
Below are two excerpts from the podcast.
Doug described World Tree's business saying, "We grow sustainable forests and farms in North America and Central America. With plans to expand into South America next year. We primarily focus on the growth of the Empress Splendor tree, which is the fastest-growing tree in the world. This species of tree grows to about 80 feet tall and 20 inches in diameter in about 10 years. (Most trees take 20 to 50+ years to reach maturity.) After this period of growth, we can harvest the trees to produce high-value lumber products for end-use as guitars, flooring, and other finished wood products."
Dough highlighted the company's scale saying, "We work with approximately 240 small farmers with about 5,000 acres planted. We plan to plant another 10,000 acres of trees over the next 12 months. Beyond this year, we truly believe the sky's the limit. We are in discussions with larger institutions to plant anywhere from 2,000 to 100,000 acres for single projects."
Here is the transcript summary of the podcast.
