Biogas production and processing from various organic wastes in anaerobic digesters and landfills

Generating biogas from the problematic quantities of organic wastes and waste byproducts produced from many manufacturing processes offers eco-friendly processing of environmentally-damaging feedstocks. Substantial biomass is generated as waste products from agriculture and forestry, industrial and urban effluents. The waste biomass typically contains large quantities of fats, proteins, starches and/or sugars making them readily digestible by anaerobic-digestion. Landfill materials are diverse and tend to be dominated by municipal solid wastes and are converted slowly and progressively to methane under prevailing anaerobic conditions in the near-sub-surface. The utilization of domestic-waste materials as raw feedstock for biogas-production plants offers sustainable solutions because it does not compete for land usage or generate toxic byproducts. Biogas production from landfills is an alternate approach to burning, composting or anaerobically digesting in purpose-built equipment.
