Methane emission reduction by adding sulfate to liquid dairy manure.

Dairy manure treatments like solid-liquid separation (SLS) and anaerobic digestion (AD) significantly reduce methane (CH4) emissions. SLS accelerated methane production speed, while both treatments lowered the overall methane potential (B0).

Area of Science:

  • Environmental Science
  • Agricultural Engineering
  • Biogeochemistry

Background:

  • Dairy manure management is crucial for reducing greenhouse gas emissions.
  • Methane (CH4) production from manure contributes to environmental pollution.
  • Solid-liquid separation (SLS) and anaerobic digestion (AD) are potential manure treatment strategies.

Purpose of the Study:

  • To evaluate the impact of SLS and AD on methane potential (B0) and production rate.
  • To compare the effectiveness of SLS and AD in reducing CH4 emissions from dairy manure.

Main Methods:

  • Laboratory assays were conducted to measure CH4 production over 202 days.
  • Dairy manure samples were analyzed before and after SLS and AD treatments.
  • Methane potential (B0) and CH4 production rates were quantified per kg of volatile solids (VS).

Main Results:

  • SLS reduced CH4 emissions by 81% and AD by 59% on a per-liter basis compared to raw manure.
  • The ultimate CH4 emission potential (B0) was reduced by 11% with SLS and up to 35% with AD.
  • SLS treatment accelerated CH4 production, with separated liquid manure reaching 90% of ultimate CH4 production fastest.

Conclusions:

  • Both SLS and AD are effective in reducing CH4 emissions from dairy manure.
  • SLS increases the speed of CH4 degradation, while AD significantly reduces the overall CH4 potential.
  • Assessing manure treatment strategies requires consideration of both degradation speed and emission potential for effective farm-scale application.
