The presentation of current German best case plant concepts concerning stable, manure management and biogas plant is planned for the second half 2019. The plants should set an example for high energy efficiency and low emissions through excellent management of liquid manure and fermentation residues. A call for proposals for best-case plant operators will be published in the course of 2019.
Deqingyuan Biogas Plant, located in Yanqing District, Beijing, is one of the best-case plants in China, which is very successful in not only environment protection, but also in business. Beijing Deqingyuan Agriculture Technology Co. Ltd (Deqingyuan Agriculture) is an ecological agribusiness. The most distinctive feature of this model is the maximization of resource use, realizing the maximum conversion of livestock manure to energy while simultaneously reducing manure pollution into the environment and creating a prototypical model of contract agriculture.
New technical concepts
In this work package, conceptual proposals for a better design and coordinated operation of stables and biogas plants will be developed. The publication of the results is planned for 2019/2020.
The ChinaRes project will identify barriers to the use of various agricultural residues from animal husbandry and plant production. Data from various surveys, (online) questionnaires for farmers and authorities will be collected and analysed to provide a basis for the provision of technical, economic and non-technical approaches to optimisation. The publication of the results is scheduled for 2019/2020.
With regard to the recording of identification to the energetic use of liquid manure and residual materials, biogas plant operators were questioned as part of the annual operator survey. More information and the results of the survey >>>
Which substrate potentials are available and which are yet unused? The barriers to the enegetic use manure in German biogas plants have been identified in the Survey of lifestock farmers (without biogas plants) >>>
Emissions (manure storage)
DBFZ and ATB have developed a method to investigate the effects of slurry storage. The experimental set-up will determine the methane formation potential and the emission potential of slurry at selected times during the storage phase. A corresponding test bench was built at the project partner DBFZ. The publication of the experimental results is planned for 2019/2020.
