Description

Debkumar Chakraborty leads a seven-author team studying in 2026 how to ferment mixed kitchen waste into hydrogen and useful acids without chemical crutches. Their two-stage system pairs a leached bed reactor with an airlift reactor, feeding it either food waste alone or a blend weighted toward fibrous vegetable waste, whose tough plant fibers slow digestion. Enzyme activity and the broth's natural buffering were tracked through the acid-making stage.

Both feeds buffered themselves impressively, peaking within the first five days with no additives needed. The fibrous blend tamed hydrolysis speed, steadied acidity, and nearly doubled acetate yield, though plain food waste won on hydrogen output and climate footprint in the life cycle check. Recirculating the second reactor's effluent replaces chemicals, pointing to cheaper waste-to-resource plants.
