Bio Business of GS Caltex
Commercial production of biodiesel and investigation of a new bio-project by various
R&D activities
Bio Business and Projects
Energy
 Biofuel for Diesel
- Mandatory use of biodiesel from 2012 in South Korea
- GS Bio, our subsidiary company currently producing biodiesel (Capa. : 100,000 ton/yr) at
Yeosu refinery complex in South Korea
 Biofuel for Gasoline
- Biobutanol process development in accordance with future governmental policy
Chemicals
 Biopolymers
- Development of renewable or biodegradable polymers using bio-based intermediates
production (Nylon 4, PTT, etc)
 Value added chemicals
- 2,3-Butanediol production from biomass and development of its derivatives (e.g.
butadiene)
- Finding new application of crude glycerin, a by-product from biodiesel production

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

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

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
