  • Farmers use manure or composted manure as fertilizer for crops which reduces or eliminates the need for commercial fertilizers and chemicals industrial livestock production concentrates large numbers of animals in one area.
  • Livestock, manure, and fertilizers contain large amounts of methane and nitrous oxide, making them primary emitters of these gases (foley et al) the harmful impact agriculture has on the environment will only increase with time, especially since the world population is continuing to rise, and with it rises the danger of food scarcity.
  • However, roughly half the technical potential of renewable methane, from livestock manure, cannot be economically delivered to the gas grid for use in transport or heat even with very high policy incentives equivalent to €4 per m3 or roughly €4 per liter transport fuel (diesel equivalent.
