Applications
Targeting industrial polymer waste streams where conventional mechanical and chemical routes prove ineffective or economically unviable.
Focus areas
Where Envalyx creates value
Each pathway is co-designed with partners to respect existing collection and processing infrastructure while producing specification-ready intermediates.
PA-6/PA-66
Feedstock: Automotive components, e-mobility housings, industrial textiles.
Today: Often landfilled or downcycled due to glass fiber reinforcement, high crystallinity, and thermal sensitivity.
Envalyx pathway: Engineered enzymes selectively cleave amide bonds under mild aqueous conditions to recover monomers suitable for repolymerization (target).
Target products
- Adipic acid for PA-6/PA-66 synthesis
- Hexamethylenediamine (HMDA)
- Repolymerization feedstock (target)
What we need from partners
- Feedstock format (flakes, foam, film, crumb)
- Known additives & contaminants
- Estimated annual tonnage range
- Geography + timeline

Polyurethane foams
Feedstock: Post-consumer mattresses, appliance insulation, flexible manufacturing scrap.
Today: Often landfilled or incinerated. Thermal processing degrades polyol quality.
Envalyx pathway: Engineered enzymes cleave urethane linkages (–O–CO–NH–) to release polyols, amines, and CO₂ under mild aqueous conditions.
Target products
- Polyols suitable for polyurethane manufacturing (target)
- Recovered amines for chemical use
Quality outcome: Targets molecular-weight retention for reuse
What we need from partners
- Feedstock format (flakes, foam, film, crumb)
- Known additives & contaminants
- Estimated annual tonnage range
- Geography + timeline

Multilayer films & complex packaging
Feedstock: Barrier films, pouches, and laminates with PA, EVOH, PET, and PE layers.
Today: Multiple incompatible layers with different melting points. Adhesives contaminate mechanical processing streams.
Envalyx pathway: Sequential enzyme targeting enables layer-by-layer depolymerization, producing clean streams per polymer type.
Target products
- PA monomers (adipic acid + HMDA)
- PET monomers (TPA + EG)
- EVOH fraction (recovered feedstock)
- Separated PE for mechanical recovery
What we need from partners
- Feedstock format (flakes, foam, film, crumb)
- Known additives & contaminants
- Estimated annual tonnage range
- Geography + timeline

Tire rubber & elastomers
Feedstock: End-of-life tire crumb, NR/SBR/BR-rich rubber fractions, and elastomeric industrial scrap.
Today: Sulfur-crosslinked rubber networks, carbon black, fillers, oils, steel/textile residues, and additive packages make direct reuse difficult.
Envalyx pathway: Substrate-aware enzyme systems are evaluated for surface opening, oxidative polyisoprene attack, and fragment/additive cleanup.
Target products
- Oxidized isoprene oligomers and carbonylated rubber fragments (target)
- Additive/filler-associated fractions for partner evaluation
- Process data for integration with partner tire-recovery workflows
Quality outcome: Prioritizes realistic feedstock handling, additive awareness, and compatibility with existing tire-processing infrastructure
