Bio Strategy and Activities
Bio-Strategy
Support and Supplement for existing oil and petrochemical industry with bio-based energy and
products
Transformation of low-value by-products(or wastes) into high value added products
Pre-emptive response to government policy
Open Innovation
Strategy for strong buildup of technical value chain and timely, effective development
Global network utilization including university, research institute, company, etc
Collaboration with feedstock suppliers, plant owners for renovation needs, and people who are
interested in commercial co-production and joint marketing
Main Activities
Core technologies development such as strain, fermentation, separation, and pretreatment
Integrated process optimization of core technologies
Process design and engineering for commercial scale up

What is Biobutanol?
Biobutanol is a valuable product as chemical and fuel
Substitute for petroleum based butanol
An advanced biofuel that has many benefits over ethanol
As transport fuel
High Energy Density
Low Water Solubility
Low Corrosive
Biobutanol
Low Vapor Pressure
Issue of biobutanol commercialization
Low final butanol concentration ( < 20 g/L)
Low butanol productivity ( < 0.5 g/L/hr) due to low cell density
Low yield of butanol due to hetero-fermentation (0.28~0.33 g/g)
High cost of butanol recovery from low-concentration yields
GS Caltex develops proprietary bacteria and process for biobutanol production!!

Biobutanol Development-Microbe
Strain Development
Key success factor to increase production performance such as yield, titer, productivity, and selectivity
Eliminating co-production pathway of acetone and ethanol (approx. 40% of final products)
Various types of genetically modified strains with breakthrough performance secured
Ready for the commercial production of biobutanol

Biobutanol Development-Process
Process Development
Continuous fermentation process using in-situ butanol recovery with high yield and productivity
Our technologies are at a world-leading level : high performance microbe, high productive bioreactor
and separation process with low energy consumption
For energy saving, dehydration process is ideally combined with membrane and distillation
Integrated process and optimization could be developed by simulation techniques and engineering
know-how
Basic design for commercial biobutanol plant is almost completed
Patent
More than a dozen of patents and patent applications for the innovative biobutanol process

Lignocellulosic Biomass Utilization
Development progress for utilizing 2nd generation biomass
Overcome the ethical concerns of food (1st generation biomass) as fuel
Reducing the production cost of biofuel and biochemical in the near future
Conducting a research on applications of various types of biomass to produce biomaterials and coworking with SUDOKWON Landfill Site (capital region of Korea) Management Corp (waste wood)
Pretreatment issues for cellulosic biomass
Considering a variety of pretreatment technologies such as acid,
base, and enzyme
Reviewing process for low operating costs and capital expenses,
as well as high yield of hydrolysis
Pretreatment
Dilute acid, Base,
Enzyme, etc

2,3-Butanediol Development
What is 2,3-Butanediol?
• One of the constitutional isomers of butanediol, catalyzing to Butadiene and MEK (methyl ethyl ketone)
• Produced by microbial fermentation from various biomass, including molasses, starch, lignocellulosic
materials, and crude glycerol
Our status for 2,3-Butanediol
• New robust genetically engineered strains, producing 2,3-Butanediol as similar levels of ethanol with
respect to titer, yield and productivity
• A novel and effective 2,3-Butanediol recovery process using solvent extraction
• A novel dehydrating process from 2,3-Butanediol to Butadiene and MEK using self-developed catalyst
