High-solids countercurrent fermentation efficiently converts waste into carboxylic acids. Cattle manure offers rapid fermentation, while mixed waste provides higher acid yields.

Area of Science:

  • Biotechnology
  • Environmental Science
  • Chemical Engineering

Background:

  • Lignocellulosic biomass presents a sustainable feedstock for chemical production.
  • Efficient conversion of waste streams into valuable products is crucial for a circular economy.

Purpose of the Study:

  • To develop and evaluate equipment and procedures for high-solids countercurrent fermentation of lignocellulosic biomass.
  • To investigate the production of carboxylic acids from different waste feedstocks.

Main Methods:

  • Development of specialized equipment for high-solids countercurrent fermentation.
  • Fermentation of cattle manure and a mixture of municipal solid waste/sewage sludge.
  • Analysis of fermentation rate, acid concentration, and acid yield.

Main Results:

  • Cattle manure fermentation: rapid rate (2.98 g/L/d), high concentration (32.5 g/L), but low yield (0.24 g/g VS).
  • Mixed waste (80% MSW/20% SS) fermentation: slower rate (1.98 g/L/d), lower concentration (26.5 g/L), but higher yield (0.34 g/g VS).

Conclusions:

  • High-solids countercurrent fermentation is a viable method for carboxylic acid production from waste.
  • Feedstock selection impacts fermentation performance, with mixed waste showing potential for higher acid yields.
