Valorization of pectin fibrous residues into high value functional materials
Innotech Materials, LLC proposes a catalytic process that converts pectin production side streams into compostable, PFAS-free cellulose composites with tunable hydrophobicity, mechanical strength, and barrier properties. These reinforced materials offer a sustainable alternative to fluorinated and styrenic plastics in building and construction applications, while valorizing an underutilized agricultural waste stream.
Overview
Innotech Materials, LLC is developing a technology platform that transforms pectin fibrous residues—an underutilized agricultural side stream—into high-performance, compostable cellulose composites. The proposed process uses catalytic oxidation and controlled crosslinking to upgrade this clean, food-grade waste stream into functional materials with tunable hydrophobicity, mechanical strength, and barrier properties. These PFAS-free composites are designed to replace toxic plastics such as fluorinated and styrenic materials in building and construction applications, offering a renewable, non-toxic alternative that supports circular economy goals.
Technical specifications
Core technology features:
- Catalytic oxidation produces hydrophobic nanocellulose and enables controlled crosslinking, creating a composite platform with tunable structure and performance.
- Fatty-acid modification further increases hydrophobicity, yielding higher water-contact angles and improved moisture-barrier properties.
- Crosslinked cellulose fibers, when blended with hydrophobic nanocellulose, form composites with enhanced mechanical strength and moisture-barrier performance.
- The process is simple, quantitative, and compatible with pectin fibrous residues.
Planned validation activities:
- Preparation of crosslinked cellulose via catalytic oxidation of pectin residues, followed by controlled crosslinking to generate mechanically enhanced composites.
- Characterization of hydrophobicity through water contact angle measurements and assessment of mechanical strength to confirm structural integrity and application suitability.
- Manufacturing of nonwoven hydrophobic crosslinked cellulose composites by formulating blends of hydrophobic nanocellulose with cellulose at controlled ratios (e.g., 5%, 10%, 20%) to modulate hydrophobicity.
- Production of nonwoven sheets using a wet laid process.
Technology readiness level
The project is at an early stage, aiming to establish proof of concept for hydrophobic, cellulose-based composites derived from pectin production residues. The catalytic oxidation and crosslinking chemistry has been developed, and future validation will focus on characterizing hydrophobicity, mechanical strength, and moisture-barrier performance, as well as demonstrating nonwoven sheet manufacturing. The technology is positioned for collaborative development and pilot-scale validation with industry partners.
