Product classes of chemical industry
• Products from petrochemistry
• Products from industrial biotechnology
Industrial chemicals
Polymers
Agrochemicals
Elastomers
Oleochemicals
Solvents
Pharmaceuticals
Paint
Alcohols
Amino acids
Organic acids
Vitamins
Common feature of petro- and biochemicals:
Carbon as backbone

Biorefinery – looking into (far) futureEnergy vs. “use as matter” (chemicals, materials, food, feed)
Renewable resourcesBiorefineries

Fossil resourcesPetrochemistry(Energy and chemicals)
We need “CARBON” to produce materials and chemicals.We don’t necessarily need “CARBON” for energy production.

Products from White Biotechnology
• Organic acids– lactic acid: building block chemical, polymers– succinic acid: building block chemical– citric acid: food, detergents, industry
• Amino acids– Lysin: food, feed– Amino acid precursers: building block chemicals, polymers
• Alcohols– Ethanol: biofuels– Butanol: biofuels, solvents– Propanediol: building block chemical, polymers
Produced from sugarMetabolic engineering = essential technology to direct the process from substrate to product
