When biodegradable waste decomposes, landfill gas is produced. There are two main components of landfill gas, methane (which accounts for approx 50%) and carbon dioxide (which makes up the remaining 50%).
Methane (CH4), is a potent greenhouse gas which has around 25 times the global warming effect of carbon dioxide (CO2). Methane is odourless and highly flammable.
Carbon dioxide, is the more popular, or ‘well-known’ greenhouse gas, it is also odourless but non-flammable and is present in our atmosphere.
Australian Dynamic Technologies supply a complete range of portable monitors for analysing gases which exist from landfill and/or contaminated land areas.
