How can I calculate the carbon credits of waste reduction projects?
The input material would be naturally transformed in carbon dioxide and methane, plus H2S in percentages linked to different ambient conditions. If you know the organic matter of the waste, you can calculate the theoretical methane production, considering that : 1 kg of organic matter is 1.23 kg COD and 1 kg COD produces 350 NL of methane. FAQ: Do I need to heat the process? Methnogenesis in a biogas plant is an exenergonic reaction. So heat is generated but so slowly that it is a very minor factor in most digesters. The dominant factors in the heat balance tend to be: • heat losses to the air and ground (except in very warm climates or with very good insulation or at very large scale) • heat losses in the digestate (maybe offset by using it to preheat cold feedstock) • heat losses to the feedstock (it is often well below the digester temp and if it isn’t very strong you’ll be adding a large volume every day) • heat gains from the feedstock (if it’s hot – but that’s much rarer) • any c
