Biogas Done Right - Introduction (2019)

Jorge Hilbert explains and introduces the importance of biogas in the agricultural sector, while additionally explaining biogas’s potential for increasing future energy efficiency and technological sustainability.

Using Animal Manure as a Resource (2019)

Anaerobic digestion, or AD, is the biological process that breaks down biological materials like compost or manure into biogas. Livestock manure accounts for 3 percent of man-made methane emissions globally. Methane, when captured and stored, can be used to generate electricity and heat, or it can be processed into natural gas fuel. By capturing the biogas, we are also preventing the release of methane, one of the most potent greenhouse gases, to the atmosphere.

Methane Mitigation Matters: Climate Change (2015)

Methane is a prevalent manmade greenhouse gas that traps 28 times more heat than carbon dioxide (CO2). Reducing methane emissions by recovering and using methane as a clean energy source offers many benefits for the environment and local communities. This video highlights the many ways that reducing methane can benefit the environment and local communities.
