Hemicellulose, a heterogeneous polysaccharide composed of glucans, xylans, and mannans, is a critical structural component of plant cell walls. Abundant in agricultural residues (e.g., straw, husks), food processing byproducts, and pulp/paper waste, its extraction aligns with circular economy principles by transforming low-value biomass into renewable materials. The recovery process holds dual environmental and industrial significance, reducing agro-industrial waste while providing feedstocks for bio-based polymers and chemicals.

Hemicellulose recovery employs physical methods like mechanical fractionation and centrifugal separation, alongside chemical approaches such as acid/alkali-assisted solubilization or enzymatic hydrolysis.  Keysino enhances these conventional techniques with proprietary membrane filtration and selective precipitation systems, achieving over 85% recovery efficiency with minimal lignin interference.  This scalable solution enables high-purity hemicellulose production for applications ranging from biodegradable films to green adhesives, while significantly lowering the ecological footprint of waste streams.
