Petrochemicals account for 7% of global emissions and drive over a third of oil demand—yet they remain one of the most overlooked contributors to climate change.Meanwhile, more than four billion tons of plant biomass waste are generated globally each year—containing enough carbon to entirely replace petroleum-derived chemicals.Hyfé tackles this challenge with a novel biorefining platform that converts low-value plant waste into high-value chemical intermediates. This enables the production of the same essential materials—without relying on petroleum. Our technology can double the output of critical chemicals, preserve strategic oil reserves, redirect billions into strengthening the food processing sector, and power domestic manufacturing that revitalizes rural communities.Led by a team with decades of experience in oil refining and industrial scale-up, Hyfé is uniquely positioned to commercialize the refining infrastructure of the future.  __________Equal Employment Opportunity: Hyfé is an equal opportunity employer, and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity or expression, pregnancy, age, national origin, disability status, genetic information, protected veteran status, or any other characteristic protected by law.

Petrochemicals account for 7% of global emissions and are projected to drive over a third of the growth in oil demand by 2030, surpassing sectors like aviation and shipping. By 2050, an additional 7 million barrels of oil per day will be required to meet the rising demand for plastics, fertilizers, and other essential products. Despite its massive environmental footprint, the petrochemical industry remains an overlooked contributor to climate change.At the same time, over four billion tons of plant biomass waste are generated globally each year—containing more than enough carbon to replace petroleum-derived chemicals entirely. Biorefineries convert this biomass into platform chemicals, such as glucose, ethanol, and organic acids, which serve as building blocks for producing plastics, solvents, and fertilizers. In harnessing the carbon potential within biomass, this technology enables a direct pathway to displacing petrochemicals and represents a significant opportunity to reduce emissions and build a sustainable, circular economy. Unlike traditional biorefineries, Hyfé leverages food processing waste, such as grape pomace and carrot peels, which are rich in high-value specialty chemicals. By extracting these components, Hyfé achieves 5X revenue than traditional outputs, enabling platform chemicals to be competitively priced and biorefineries profitable at any scale.
