Biosynthetic ethylene & bio-ethylene oxide
Producing the world's most ubiquitous petrochemical building block from renewable biomass and captured carbon.
1 · What it gives
Ethylene is the fundamental building block of the global petrochemical industry, traditionally produced via highly energy-intensive steam cracking of fossil naphtha or ethane. Biosynthetic ethylene and its critical derivative, bio-ethylene oxide (bio-EO), are instead produced primarily through the catalytic dehydration of renewable bioethanol. By providing an exact, chemically identical “drop-in” molecule, bio-ethylene allows the plastics, packaging, and surfactant industries to aggressively decarbonize their supply chains without re-engineering downstream manufacturing infrastructure. Global capacity is surging as FMCG brands mandate sustainable packaging.
The key directions of biosynthetic ethylene are:
- Bio-Polyethylene (Bio-PE): polymerizing bio-ethylene to create green plastics for packaging, saving up to 3 tons of CO2 per ton of plastic.
- Bio-Ethylene Oxide (Bio-EO): oxidizing bio-ethylene to produce green surfactants, glycols, and PET resins for the textile industry.
- Ethanol-to-Ethylene (EtE): optimizing the catalytic dehydration process to reach 99%+ conversion efficiency from 1G and 2G bioethanol.
- Gas Fermentation (Gas Fermentation): utilizing engineered microbes to convert industrial off-gases directly into ethanol or ethylene precursors.

7 · Tech stack & innovations
Producing bio-ethylene requires massive chemical engineering scale and highly stable catalytic processes.
- Catalytic Dehydration (EtE):
- The endothermic dehydration of ethanol (C2H5OH → C2H4 + H2O) occurs in fluidized or fixed-bed reactors at 300–500°C.
- Advanced zeolite and synergistic alumina catalysts ensure >99% ethylene selectivity, preventing the formation of diethyl ether byproducts.
- Direct Microbial Synthesis:
- Emerging synthetic biology approaches utilize engineered cyanobacteria or E. coli containing an ethylene-forming enzyme (EFE).
- Allows microbes to convert CO2 and sunlight directly into ethylene gas, which bubbles out of the bioreactor for continuous collection.
- Ethylene Oxide (EO) Synthesis:
- Bio-ethylene is subjected to direct oxidation over a silver-based catalyst at 250°C.
- Bio-EO is highly reactive and explosive, requiring complex, tightly controlled micro-channel reactors before being converted to stable glycols.
