There’s a moment in every young company when you stop talking about what you’re going to build and start hiring the people who can actually build it. For our biorefinery, that moment is now.
I’m pleased to introduce Dr. Rajdeep Deka, who has joined FiberX as our Director of Biorefinery Technology and Processes. A biorefinery is the plant-based cousin of an oil refinery: instead of cracking crude oil into fuels and chemicals, it takes the woody, fibrous parts of plants and separates them into the building blocks for materials we use every day. Rajdeep will lead development of the processes that turn agricultural and forestry residues — corn stalks left after harvest, wheat straw, sugarcane bagasse, wood chips, sawmill trimmings, and more — into resins, foams, adhesives, and other bio-based chemical feedstocks that American manufacturers can put to work.
Why This Hire Matters
Almost every plant on Earth — from a cornstalk in an Indiana field to a pine tree in a Georgia forest to the switchgrass on a roadside — is built from the same three things: cellulose, hemicellulose, and lignin. Together they’re called lignocellulosic biomass, which is a mouthful for a simple idea: the woody, fibrous parts of plants that don’t end up as food. It’s the most abundant renewable carbon on the planet, and most of it today is burned, returned to the soil, or left unused.
For decades, the industry that did try to use it treated lignin as an afterthought — the part you burn for heat once you’ve pulled out the sugars. That throws away a very useful molecule. Lignin is nature’s own hardener, the stuff that lets a cornstalk stand up in an Indiana wind and a Douglas fir hold up a hundred feet of trunk. Handled correctly, it becomes the backbone for epoxy resins, polyurethane foams, and the adhesives and coatings that today are made almost entirely from petroleum.
Rajdeep has spent the better part of a decade figuring out how to handle it correctly. His doctoral work at Purdue University built an integrated “lignin-first” biorefinery for crop residues: get the lignin out intact before you do anything else, break it into clean chemical building blocks, and turn those into finished materials that perform. The same approach applies whether the feedstock is corn stover in the Midwest, wheat straw on the Plains, or wood residues from a Southern pine mill. He’s a co-inventor on three patent applications from that work and served as principal investigator on multiple grants focused specifically on scale-up. That last part is the one I care about most.
A Scientist Who Has Worked on the Plant Floor
Here’s what sets Rajdeep apart from a lot of very smart people in this field. Before his Ph.D., he spent years as a process engineer at Honeywell and Indian Oil Corporation, supporting refinery design, commissioning, and performance monitoring for real operations. He knows what it takes to get a process from a flask to a plant that runs every day and makes money.
That matters because the hard part of what we do isn’t the chemistry. Plenty of good chemistry dies in the lab. The hard part is building the process, the equipment, and the economics that let a good idea become a commercial product made here in the Midwest, not licensed to someone overseas. Rajdeep has lived on both sides of that gap, and that’s exactly the kind of person we want closing it.
The Purdue Connection
Rajdeep’s arrival also deepens our relationship with Purdue University, where our biorefinery work is already underway in partnership with the Davidson School of Chemical Engineering. He holds both his Ph.D. in Agricultural and Biological Engineering and his M.S. in Chemical Engineering from Purdue, and he has presented his research at AIChE, the American Chemical Society, and the Lignin Gordon Research Conference. His B.S. in Chemical and Polymer Engineering is from BIT Mesra.
What’s Next
Rajdeep’s job is straightforward to describe and hard to do: take what works at the bench and prove it works at scale, with numbers a customer and an investor can both stand behind. We’ve got the feedstock, the partners, and the market. Now we’ve got the engineer.
