As the energy system expands, more and more stakeholders are involved. The decentralization of the energy system is no longer a surprising factor, but synergies with agricultural activities are becoming more and more apparent. Farmers face the huge challenge of climate change. Livestock farming is increasingly recognized as environmentally damaging, but there is still a lack of technology to decarbonize this sector. Manure-to-energy conversion is already advanced and cost-effective, but daily emissions from livestock are still a problem. In addition, unsustainable tillage also leads to higher emissions instead of fixing carbon in the ground. Food waste is another major problem, both from the processing of the produce grown and from the non-consumption of the finished product. Manure treatment plants can also help solve this problem.
