In relation to our biogas launch, there has been spent some time visualizing where the biogas comes from and how it is produced, which has led to the following result:
- In the biogas plant, manure, waste, and sludge are mixed in the receiving tank. Then is the mixed material heated to between 38 and 52 degrees and is pumped into the reactor, where the biogas itself is produced. The biomass is stored in the reactor for up to two or three weeks.
- The degassed manure, which is a residual product from the biogas production, can, after the time in the plant, be sorted out and used as nutrients for the soil in agriculture. This type of degassed fertilizer is better than artificial fertilizer, as there are fewer odor nuisances, and fewer greenhouse gases bound to the fertilizer when it is spread out on the field.
- After the nutrients have been spread out in the field, it will turn into various crops that can either become animal feed, food for the shops or the straw on which the animals stand.
- These crops are harvested at some point and can in this particular case be compressed into animal feed for the cows.
- The barn is where both the animals are fed, but also where much of the waste for the biogas plant is produced in the form of residual straw and manure.
- The manure and the remaining waste are then collected and transported into the plant, where this process starts all over again.
After the two to three weeks in the biogas plant, the biogas is pumped directly into the gas network. Here, the biogas is used as a fuel for boats, planes, trains, and heavy transport.
