Development and Implementation of the Danish Centralised Biogas Concept — Financial Aspects

9. Conclusions

Considerable efforts in developing the centralised biogas concept in Denmark have been carried out over the last 15 years. As a result, today 20 plants are in operation. Its has been demonstrated how centralised biogas plants, as integrated energy production, waste treatment and nutrient redistribution facilities, make a valuable contribution to the solution of a range of problems in the fields of environment, agriculture and energy.

Gradually improved economic results lead to a situation where most of the plants today find themselves in an acceptable economic situation, as operation stability has been improved significantly over the years, and satisfactory levels of biogas production is achieved by most plants.

Treatment of organic waste in centralised biogas plants has proven to be an economically favourable and environmentally advantageous option, in waste treatment and recycling.

Farmers involved in centralised biogas plants do not withdraw a profit from the biogas companies. Instead they gain derived economic benefits in the form of cost savings in manure storage and transportation, and in fertiliser purchase.
