Chrome leather production creates significant waste. Implementing clean tanning technologies and complementary wastewater treatment, including anaerobic treatment for sulfide and energy recovery, is crucial for cleaner production.

Area of Science:

  • Environmental Science
  • Chemical Engineering
  • Industrial Ecology

Background:

  • Tanning, especially chrome leather production, exhibits inefficient raw material utilization and generates substantial polluted wastewater and solid waste.
  • Current tanning processes contribute significantly to environmental pollution, necessitating improved waste management strategies.

Purpose of the Study:

  • To highlight the importance of integrating clean production technologies with effective waste treatment in chrome leather manufacturing.
  • To emphasize the role of anaerobic wastewater treatment in mitigating pollution and recovering valuable resources.

Main Methods:

  • Review of existing clean tanning technologies and waste treatment processes.
  • Analysis of anaerobic wastewater treatment for sulfide and sulfur recovery.

  • Assessment of biogas production as an energy source from wastewater treatment.

    • Main Results:

    • Clean tanning technologies can prevent a portion of emissions.
    • Anaerobic wastewater treatment offers a viable method for recovering sulfides, sulfur, and energy (biogas).
    • Designed complementarity between clean production and waste treatment is essential for integral clean chrome leather technology.

    Conclusions:

    • Integral clean chrome leather technology requires a synergistic approach combining cleaner production methods with advanced waste treatment.
    • Anaerobic wastewater treatment is a key component for resource recovery and pollution reduction in the leather industry.
    • Implementing these integrated strategies can lead to more sustainable and environmentally responsible chrome leather production.
