How does Biffa contribute to climate change?
There are many gases that are referred to as greenhouse gases (GHG) that contribute to climate change, though the most significant greenhouse gases are generally accepted as;
- Carbon Dioxide (CO2)
- Methane (CH4)
- Nitrous Oxide (N2O)
- Hydrofluorocarbons (HFCs)
- Perfluorocarbons (PFCs)
- Sulphur hexafluoride (SF6)
With regards to Biffa’s activities the most significant emissions of greenhouse gases resulting from our activities are carbon dioxide (CO2) and methane (CH4).
Carbon dioxide is produced when any form of carbon is combusted or broken down. Biffa’s main sources of CO2 are:
- Process emissions (those from the biodegradation of landfill i.e. methane)
- Transport fuel emissions
- Travel associated emissions
These emissions are related to collection, transportation and processing of waste.
Our landfill gas emissions are a direct result of managing society's waste. Methane is produced by the decomposition of organic material taking place in an absence of oxygen (anaerobic decomposition). Where the organic based material breaks down and biodegrades, this result in the generation of a methane rich gas commonly known as landfill gas.
