Shandong Dongying Biogas Project

Operation since: 10/2012

Input material: 90 t/d high solid cow manure

Output: 1.022.000m3/a biogas

This is the first biogas project in China were the digested manure is used as bedding for the cattle at a modern, large milk production of 5000+ cows. This is a mile stone project in environmentally friendly and harmonious waste circulation system at an intensive milk farm. The cost saving by changing to residue bedding is obvious, but in addition, we separate residue solids to organic fertilizer. Thus, we recycle valuable minerals back on the surrounding crop fields for the cattle feedstock production. The cattle are fed with maize crop and we collect back the manure.

This first-stage biogas plants treats cow manure from 1800 cows with a digester volume of 2920m3 in order to replace the sand bedding into dried digestate. At first, 2800m3 of biogas will be produced for a heating utility in the dairy farm.

For the second step, three additional digesters are planned, to treat all manure, ecologically, from 10,000 cows farm.
