VERONA, Italy -- Ethanol
to ethylene oxide (EO) and
ethylene glycol (EG) technologies could become more popular
in coming years to address a niche but growing market for
Goyal explained that recent interest in green mono ethylene
glycol (MEG) was driven by strong market interest in areas
such as green PET bottles (Coca-Cola), green PET film for
packaging (Nestle, P&G), green anti-freeze (Toyota) and
green plastics for high-end automobiles (Toyota).
"By 2018, green MEG production could be more than 30% of
total MEG used in PET [polyethylene terephthalate]," Goyal
By number, that would be almost 3,000 KT of green MEG
production -- up from about 400 in the current year of 2014.
Goyal explained that his company's integrated ethanol
to EO/EG process offers
several competitive advantages, including the flexibility to
design for excess bio-ethylene production with a quality
suitable for other downstream products such as vinyl chloride
monomer (VCM) and high-density polyethlyne (HDPE).
Scientific Design, which has 25 years of operating experience
with bio-EO/EG, notes that its process producers fiber-grade
MEG quality -- the same as with petro-ethylene. Moreover, the
company says it has strong research and development (R&)
support for continuous improvements in process efficiency and
the handling of ethanol
from traditional and
second-generation raw materials.
"This process addresses a niche but growing market for green
glycol," he said. "It's a viable option fo rregions where
petro-ethylene is either too expensive or not accessible. It
also provides flexibility to switch between petro- and
bio-ethylene based on factors such as current raw material
costs and market demands."
The Scientific Design technology
can also be a major
process link for other ethylene- or EO/EG-based bio-products,
