what is a byproduct of most landfills
Three processesâbacterial decomposition, volatilization, and chemical reactionsâform landfill gas. Bacterial decomposition. Most landfill gas is produced by bacterial decomposition, which occurs when organic waste is broken down by bacteria naturally present in the waste and in the soil used to cover the landfill. Organic wastes include food, garden waste, street sweepings, textiles, and wood and paper products.
