Breakthrough in Sustainable Lactic Acid Production from Lignocellulosic Biomass

Strategic Insights -

Scientists at Beijing Forestry University have made significant progress in the production of lactic acid from lignocellulosic biomass using heterogeneous catalysts. This innovative approach offers a sustainable alternative to conventional methods. The research, supported by the National Key Research & Development Program of China, has demonstrated the potential of La(OTf)3/SBA-15 catalysts in converting C5 sugars to lactic acid with high efficiency and recyclability.

Key Takeaways:

  • The study employed a two-step process to prepare La(OTf)3/SBA-15 heterogeneous catalysts, which were then used in the one-pot conversion of C5 sugars to lactic acid.
  • The catalyst achieved high xylose conversion rates of 98% and yielded 49.73% lactic acid, while maintaining its ordered two-dimensional hexagonal mesoporous structure.
  • The synergistic combination of La(OTf)3 with SBA-15 facilitated efficient conversion of bioresources, underscoring the potential of heterogeneous catalysts in biomass valorization processes.
  • The catalyst demonstrated commendable recyclability, maintaining an lactic acid yield of 40.03% after five cycles.
  • Research concluded that this approach offers a sustainable alternative to conventional methods of lactic acid production.
  • Mingfei Li, Jianli Qin, Chenxi Li, Liujun Liu, and Jing Bian were among the authors of this research.
  • The study was peer-reviewed and published in Acs Sustainable Chemistry & Engineering in 2025.
  • The synergistic combination of La(OTf)3 with SBA-15 facilitated the efficient conversion of bioresources, highlighting the potential of heterogeneous catalysts in biomass valorization processes.
