CO2 FROM THE ECODIGESTER
CO2 FROM THE ECODIGESTER
Chemically, CO₂ (carbon dioxide) is always the same molecule, no matter where it comes from. It always consists of one carbon atom and two oxygen atoms: CO₂. But there is, however, an important difference in origin.
But there is, however, an important difference in origin.
1. CO₂ from fossil fuel combustion
Comes from oil, gas or coal formed millions of years ago.
Burning these fuels releases "old" carbon that was not in the carbon cycle for a long time.
This adds extra CO₂ to the atmosphere and contributes to the enhanced greenhouse effect.
2. CO₂ from biological processes (as in an Ecodigester)
Comes from the decomposition of organic material, such as food waste.
Those plants and residues recently absorbed CO₂ from the air during photosynthesis.
The CO₂ released in the process is part of the natural carbon cycle. As long as the organic waste would otherwise also have decomposed, this CO₂ is usually climate-neutral.
Summary
Chemically identical: Yes, CO₂ = CO₂.
Climatically different: Yes, because CO₂ from fossil fuels contributes to climate change, CO₂ from an Ecodigester does not.
