Verdene Technology

Verdene™ technology is a suite of industrially proven process technologies from Lummus Technology for sustainable polymer producers using bio-ethanol feedstock to produce fully bio-based polymers such as polyethylene, polypropylene, super absorbent polymer. The suite offers reduced to net-negative carbon dioxide emission because of the sequestration of CO₂-based carbon in the polymer itself. The polymer is functionally the same as polymers produced from traditional hydrocarbon sources and are a sustainable drop-in solution to combat climate change.
 

Examples:

• Verdene™ PP: Bio-ethanol is converted to bio-propylene using the EtE EverGreen™ technology plus Lummus Dimer and OCT (metathesis) technology, and the bio-propylene (and bio-ethylene as comonomer) is subsequently used to produce bio-based polypropylene (bio-PP) in the Novolen® PP process.
• Verdene™ HDPE: Bio-ethanol is converted to bio-ethylene using the EtE EverGreen™ technology, and the bio-ethylene is subsequently used to produce bio-based high-density polyethylene (bio-HDPE) in the EXCENE™ HDPE process. Bio-based comonomer (1-butene) can be made by dimerization of bio-ethylene to n-butenes, which can be isomerized to 1-butene.
• Verdene™ SAP: Bio-ethanol is converted to bio-propylene using the EtE EverGreen™ technology plus Lummus Dimer and OCT (metathesis) technology, and the bio-propylene is subsequently converted into bio-based Super Absorbent Polymer (bio-SAP) using Lummus’ Acrylic Acid and Saplene™ SAP process technologies.
