Livestock Manure Management and Biogas Production for Emission Reduction

Detailed overview of innovation with sample startups and prominent university research


What it is

Manure management and biogas production involve the collection, treatment, and utilization of livestock manure to reduce greenhouse gas emissions and create valuable bioenergy. Biogas, a mixture of methane and carbon dioxide, is produced through anaerobic digestion, a biological process that breaks down organic matter in the absence of oxygen. This biogas can then be used as a renewable energy source for electricity generation, heating, or transportation fuel.

Impact on climate action

Manure Management and Biogas Production revolutionize emission reduction in livestock farming. By capturing methane from manure and converting it into biogas, it mitigates greenhouse gas emissions. This innovation curtails methane release, a potent contributor to climate change, fostering sustainable agricultural practices and advancing global efforts in combating climate change.

Underlying
Technology

This approach integrates several key technologies and concepts:

  • Anaerobic Digestion: Manure is placed in airtight digesters where microorganisms break down the organic matter, producing biogas and a nutrient-rich digestate.
  • Biogas Upgrading: Biogas can be upgraded to biomethane, a high-purity methane gas, which can be injected into natural gas grids or used as a transportation fuel.
  • Manure Separation and Treatment: Separating solid and liquid fractions of manure can facilitate more efficient handling and treatment, reducing odors and nutrient runoff.
  • Nutrient Recovery: Technologies are being developed to recover nutrients, such as nitrogen and phosphorus, from manure, creating valuable fertilizers and reducing nutrient pollution.
  • Composting: Composting manure can transform it into a stable, odor-free soil amendment, providing valuable organic matter and nutrients to agricultural soils.
