Low heat. Low pressure.
Operating at 70–90°C, our depolymerization process uses much lower temperatures than traditional heat-and-mold recycling and extrusion, reducing energy consumption.
Molecular unzipping of polymers
Denovia’s technology breaks down the polymer chains in PET plastics in as fast as minutes, yielding their constituent monomers TPA. This “unzipping” technology works on different forms of plastics - including polyester textiles and contaminated or mixed waste. TPA is then extracted from the resulting chemical mixture, purified, and optionally repolymerized into PET pellets for manufacturing new plastic products.

The Denovia advantage
Extremely fast
Denovia’s core depolymerization process breaks down PET plastics within minutes. Under certain conditions, flash depolymerization is observed.
Circular process
Many chemical outputs are reused in the next processing cycle, creating a circular and sustainable process with minimal waste.
High-quality output
Our tests with real-life plastic waste feedstocks achieved TPA purity above 99.5%* (depending on conditions), enabling high-quality downstream applications.
Form-agnostic
Our depolymerization technology works with textiles as well as mixed and contaminated waste that traditional recycling struggles to handle.
Favorable unit economics
Denovia’s technology transforms plastic waste into saleable plastic raw materials and industrial chemicals, rewriting the economics of recycling.
Typical waste types
Some of the many types of PET waste our technology can depolymerize.
Polyester textiles
Polyester clothing and mixed or contaminated fabrics.
Mixed and unsorted waste
PET-containing waste that is difficult to sort or process through traditional recycling, such as hospital garments.
Marine waste
Such as mooring ropes, fishing nets, floats and buoys.
Food and beverage containers
PET clamshell containers, trays, and beverage bottles.Denovia’s process offers two routes, each yielding different products.The two routes also produce other industrial chemicals that can be resold and used in other industrial manufacturing processes.(Different output in each)

Denovia’s technology
Relatively low heat and pressure
Handles mixed and contaminated PET waste
Advanced chemical process
High-quality output for making new plastics
Can be continuously recycled
Traditional mechanical recycling
