Commercial production of biodiesel and investigation of a new bio-project by various
R&D activities
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
Biopolymers
- Development of renewable or biodegradable polymers using bio-based intermediates pro-duction (Nylon 4, PTT, etc)
Value added chemicals
- 2,3-Butanediol production from biomass and development of its derivatives (e.g. butadi-ene)
- Finding new application of crude glycerin, a by-product from biodiesel production
Bio Strategy and ActivitiesBio Strategy and Activities
- 5 -
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
GS Caltex develops proprietary bacteria and process for biobutanol production!!
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
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

What is 2,3-Butanediol? • One of the constitutional isomers of butanediol, catalyzing to Butadiene and MEK (methyl ethyl ke-
tone)
• 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
