PET from Coca-Cola’s PlantBottle Relies on Green MEG Produced via Scientific
Intratec’s Technology Economics service offers an economic evaluation of Scientific Design’s MEG process
The first ever recyclable plastic bottle made partially from plants, Coca-Cola’s PlantBottle relies on polyethylene
terephthalate (PET) produced from terephthalic acid and green monoethylene glycol (MEG) derived from bioethanol.
Scrubber EO Stripper
The use of green MEG in the production of PET was enabled by Scientific Design (SD), which developed an integrated
process comprising the ethanol dehydration and the MEG production steps. This integration requires minimum
ethylene purification and takes advantage of heat integration opportunities. According to SD, ethanol is dehydrated
to ethylene and the reactor effluent is cooled, washed with an alkaline water solution, compressed and purified.
Then, ethylene reacts with oxygen to form ethylene oxide (EO). EO is purified and sent to the glycols reactor, where it
is reacted with water, generating ethylene glycol (EG), which is further separated into MEG, DEG and TEG.
Intratec’s Technology Economics advisory service makes a critical analysis of the process. Based on publicly available
information, the complete study evaluates the economics surrounding the technology, providing:
Estimation of Key Performance Indicators and list of equipment
Plant capital cost estimates developed using Aspen Process Economic Analyzer
Evaluation of the costs related to plant operation (raw materials, utilities, labor and other fixed costs, etc)
