Techno-economic and life cycle assessment of tannin production from spruce bark for leather industry applications

INIlmari NiiranenSFSusanna ForssellPOPekka Oinas

Key Points

  • The aim is to assess the economic viability and environmental impact of producing tannin from spruce bark for the leather industry.
  • Conducted a life cycle assessment (LCA) to evaluate environmental impacts.
  • Performed a techno-economic analysis to determine production feasibility.
  • Analysed the chemical composition of spruce bark for tannin extraction.
  • Identified significant economic benefits in using spruce bark for tannin production.
  • Demonstrated lower environmental impacts compared to conventional tannin sources.
  • Highlighted the potential of bark as a sustainable raw material for the leather industry.

Abstract

Bark, which is currently far from being utilised to the maximum, has the potential to be a sustainable source of chemicals in the future. For instance, bark contains a significant...
