Comet Bio, a manufacturer of sustainable ingredients, has been selected by Anheuser-Busch InBev (AB InBev), the world’s largest brewer, to join its 100+ Accelerator to pilot technology on brewers’ grain. The 100+ Accelerator builds off of AB InBev’s 2025 Sustainability Goals, with six challenges around smart agriculture, water stewardship, circular economy and climate action.

Through the 100+ Accelerator, AB InBev partners with companies who can deliver breakthrough advancements in sustainability and will aim to solve over 100 challenges by 2025. The accelerator will support promising ideas and high potential technologies, reflecting a vision of building a company to last for the next 100 years and beyond. Powered by ZX Ventures, the 100+ Sustainability Accelerator will run annual boot camps in nine markets followed by a 10-week program for select entrepreneurs to test and scale solutions.

“We received over 1,200 submissions from around the globe across all six challenges. After a rigorous review, 17 start-ups have been selected to join the second 100+ Accelerator cohort,” says Maisie Devine, Global Director, Sustainability Investments & Accelerator. 

Comet Bio has developed a novel process to extract nutrition from food system waste. It produces healthy ingredients such as Arrabina prebiotic dietary fiber from upcycled crop leftovers. Its technology is touted as integrating seamlessly with traditional food production systems, making it a sustainable process. 

Last November, Comet Bio achieved self-affirmed Generally Recognized as Safe (GRAS) status for its Arrabina dietary fiber ingredient. At the time, Richard Troyer, CEO of Comet Bio said, “Obtaining GRAS status is a significant milestone for the commercialization of our ingredient and is an indication of our strong commitment to the efficacy and safety of our ingredients. This status allows us to better serve our customers in the food, beverage and supplement categories with confidence.”

“We are excited to partner with AB InBev to pilot their saved grains in our process. AB InBev’s Waste to Wellbeing Challenge aligns perfectly with Comet’s core capability of extracting nutrition from food system waste,” explains Troyer.

The selected 17 applicants will receive support, mentors and funds so AB InBev can incubate, experiment and amplify their solutions at scale.
