Area of Science:

  • Environmental Science
  • Waste Management
  • Air Pollution Control

Background:

  • Odorous emissions from composting facilities pose environmental and community challenges.
  • Effective odor reduction strategies are crucial for sustainable waste management operations.
  • Biological waste gas treatment systems are commonly employed for odor control.

Purpose of the Study:

  • To evaluate the odor reduction efficiencies of various biological waste gas treatment systems.
  • To identify effective biofilter materials for composting facilities.
  • To compare the performance of open and enclosed composting systems regarding odor control.

Main Methods:

  • Investigated biofilter/bioscrubber combinations at various scales.
  • Tested different biofilter materials, including screened compost and a coke-compost mixture.

  • Identified key odorous substances and measured their reduction rates in different treatment systems.

    • Main Results:

    • Biofilters were primarily responsible for efficient odor degradation.
    • Screened compost demonstrated high odor degradation rates, proving to be a cost-effective biofilter material.
    • Screened compost outperformed a novel coke-compost mixture in degradation efficiency.
    • Enclosed composting systems exhibited advantages over conventional open single-bed biofilters for odor management.

    Conclusions:

    • Screened compost is a highly effective and economical material for biofilter applications in odor control.
    • The choice of biofilter material significantly impacts odor reduction efficiency.
    • Enclosed composting systems offer superior odor management capabilities compared to open systems.
