This study assesses the economics of producing butanol from corn using a novel Clostridium strain. Optimized yields and feedstock prices significantly impact butanol production costs, influencing its market viability.

Area of Science:

  • Biotechnology
  • Chemical Engineering
  • Biofuels

Background:

  • Acetone, butanol, and ethanol (ABE) production is a key area in biofuel research.
  • Developing efficient microbial strains for butanol production is crucial for economic feasibility.
  • Corn is a widely available feedstock for fermentation processes.

Purpose of the Study:

  • To conduct an economic assessment of butanol production from corn.
  • To evaluate the impact of a new hyper-butanol-producing strain (Clostridium beijerinckii BA101) on production costs.
  • To determine the projected price of butanol under various economic scenarios.

Main Methods:

  • Economic assessment of a 153,000 metric ton/year ABE production plant.
  • Batch reactor production of butanol followed by distillation recovery.

Related Experiment Videos

  • Analysis of production costs based on varying corn prices and fermentation yields.

    • Main Results:

    • With a corn price of $79.23/ton and ABE yield of 0.42 g/g, butanol price is projected at $0.34/kg.
    • An improved yield of 0.50 reduces the butanol price to $0.29/kg.
    • Increased corn price to $197.10/ton raises butanol price to $0.47/kg, with higher costs for grass-rooted plants.

    Conclusions:

    • The economic viability of corn-based butanol production is highly sensitive to corn prices and fermentation efficiency.
    • The novel Clostridium strain offers potential for cost reduction through improved yields.
    • Further optimization and consideration of by-product credits are essential for competitive butanol pricing.
